Just wondering if anyone has done this with success. I have heard of speeds as high as 2GHz and was skeptical of this being safe. I figured it would cause some overheating issues. Also what is the best app for this? If this is done is there any noticeable differences in performance(most likely as this doubles the CPU power)? How much battery life lost? Is it worth it?
Thanks
Seriously, use the search or take a peek in the dev section. 1.6 GHz is no problem at the moment. Oh, and for me, it is worth it.
Check out vipercontrol mod in dev. Section. Allows overclock to either 1.5 or 1.6ghz. PRIME CAN EASILY HANDLE this as it was tested by Asus themselves on those speeds. It was seen in the source at first but we couldn't use it. NOW Viperboy made it possible to use those higher speeds. Its more of a mild to normal overclock. Its very easy to do. You will need to install vipercontrol mod to your prime and also terminal emulator. INSTRUCTIONS are in that thread.
WE have even found another method to run parallel to vipercontrol mod to allow overclocking of all 4 cores to 1.6Ghz. Vipercontrol, St the moment, doesn't do that by itself. JUST ALLOWS normal overclocking as Asus had it.
Seems kind of odd that ASUS backed off on the performance by 30% don't you think? Maybe they just wanted to do more testing, or maybe it was a last minute change based on their first prototypes.
Mine seems OK at 1.6, but I don't feel the need to overclock it in general use - unlike my phone which I think will have a shorter life as a device anyway.

I think it was more about more money down the road. AS I'm sure you've heard of Lenovo tablet coming out months down the road. Its gonna use exact same tegra3 chip except with the 1.6ghz enabled on it.
THINK of it this way, why would Asus/Nvidia release its first quad core device already at 1.6ghz? Its already the most powerful tablet at its current state. They did this so down the line when newer tablets come out, it'll be more incentive to like the device or think it's more powerful if its clocked higher. If prime came out with 1.6ghz enabled already, then how would that look to consumers who buy tablets months later that have exact same speeds. PRIME would be the better value and those newer tablets wouldn't be all that appealing, As far as power goes. SO the newer manufacturers can have something to boast about. Like hey look at our device its clocked higher therefore more powerful. Another reason also they didn't enable it on the Prime was for battery life. At its current state, stock, prime gets excellent battery life no matter what mode you in really. HAVING 1.6ghz enabled, as I do now, drains the battery at least at the same rate as performance mode or more. PLusbif you add the extra boost to vipercontrol overclock using system tuner, then battery really drains alot faster. Because then I have all 4 cores running Max 1.6ghz at the same time. Viper control doesn't go that extreme, yet.
YOU ALSO have to remember Asus and Nvidia designed the Prime together. SO prime n tegra3 speeds are really a testing ground for future setups in future tablets. That's how we were already able to see the higher speeds a couple updates back but couldn't use them till vioerboy made it possible or you figured out how to do it with root and going into /system/etc and executing the cpu5.sh script.
I LOVE the overclock but find myself now going to stock speeds to see how they compare. STOCK speeds are really good, especially with ICS. EVERYthing is smooth n superfast.. Overclocking does make it even faster but the tradeoff is slightly faster battery drain. PLUS there's nothing out now that stock prime really can't handle. SO no real use for needing to overclock, yet. UNLESS you just want your device to be the fastest it can be. I keep switching now. Lol. Ill have it on stock speeds n as soon as I see a mention of overclock. It compels me to do it. N vs. Versa. ACTUALLY. Even with vioerboy overclock, battery life is still good. Just not as good as it would be on stock configuration. Now once bootloader unlocked, we will see overclocking paired with undervolting. So we can get Max speed and Max battery life. Or at least get the overclock to get same battery life or better as stock configuration. DONT be surprised if you see us hitting 2Ghz overclock soon. Its coming. Then if paired with system tuner, we could have all 4 cores running @ 2Ghz a piece all at the same time. unbelievable!
This morning I restarted my prime and im looking at system tuner pro...
All 4 cores are active and stuck on either 475mhz or 1.2mhz!
I didn't change anything...governer is interactive 102-1.6mhz limit....the cores wont turn off or scale down. It would usually scale down to 102mhz and turn off 2 cores...but they're all online...
FAST is good but it's killing my battery =P
Anyone know whats going on?
Pretty sire this is across the board for the most part. This happened after update to ICS or last update. Ive noticed it also but it scales to other frequencies also. Doesn't seem to effect battery too much. Your best bet if you worried about battery is to throw it in power savings mode in Asus quick settings. But no matter what mode its in, it seems to like to stay near maxed out. Maybe Asus adjusted the frequency timing to speed up things in ICS.
apologies
I'm sorry, I didn't see any other posts about this issue.
Thanks for your input
Yeah, I've had the same problem since the ICS update, but still can't find a solution, so I'm waitng for recovery and back to HC.. And, btw, it's killing my battery - it barely holds a whole day since then..
This seems like a plausible explanation for all the reboots people are seeing. With ICS the processor is kept in a more active state which uncovers wafer defects and heats up the SoC until it goes into protection mode.
Some processors handle the load better than others and it seems the spread is veeeery wide. nVidia is probably supplying Asus with parts from all bins, if they even bother to quality check and rate their parts after coming off the production lines.
I would argue that nVidia's thresholds for what is considered a passable Tegra 3 chip are way too low for real world applications.

Maybe. I can run overclocked to 1.6Ghz n still be fine no reboots. Like you said, not all chips exactly the same though. Small variances between all chips.
I'm hoping/assuming ASUS is aware of this, but just in case they're not, has anyone brought this to Gary's attention?

I'm sure they do know already. Probably amped the frequency timing up so ICS can stay as smooth as it is. It may get adjusted in new update we supposed to get any day now. New update "supposedly" fixes alot of issues.

Just took a look on system tuner, mine still scales down to 102Mhz. Not all 4 cores on all the time. It does like to stay in the higher range though alot. It all depends on what you doing and what you have running in background also.
mine used to scale down to 102mhz as well...and usually with the 3rd and 4th core offline
Odd that it has changed....
Thanks for all the input...im gonna try and see if manually updating to ICS will make any difference
*edit: I put the update file into the system root but TFP won't prompt/recognize the update...guess it won't make a difference....I'll try backing up then doing a factory reset
I'm seeing something a little different. Mine scales all over the place, except it barely ever hits 1300MHz or 1400MHz, even when set on Performance and gaming/benchmarking. For example, right now, mine only show 3 seconds on 1400MHz and 5 seconds on 1300MHz, out of 13 hours uptime.
I think ASUS and Nvidia have some work left to do in getting the Tegra 3 optimized. I'd really rather mine actually use its fastest stock speeds when in Performance mode.
Overclocking?

How did you get to overclock? I rooted mine, but had to return it because of problems. However, I couldn't overclock it either.
What's yur secret?
Update: Did a factory reset and all 4 cores are still online 425mhz-1.2 =(
Seems like my i/o speed just got worse and now there's severe lag...
*sigh* - will just wait for unlocked bootloader

Where you been? Lol we've overclocked for a good while now. Head over into Android developement section of prime. Then check out the "Vipercontrol" thread. Very easy to install n setup.

That's how its supposed to be. It doesn't run at top speed full time..lol your battery wouldn't lastlong at all if it did that. It only hit tops speeds when needed. Then it scales back when not needed anymore.
As far as your timing showing only a few seconds at top speed, all that means is you didn't do anything the prime needed top speeds for.
If you want to run at full speeds all the time I have your solution. If you rooted get System tuner app. Then open app up. Go to CPU tweaks. There it shows you what all 4 cores are running a piece in real time. The governor should be on default interactive mode. All you do it put governor on performance mode. Then raise your minimum speed up to the Max. Now your prime will be running at top speeds all the time. Now beware though, expect battery to drain alot faster.
I did that trick with my overclock n can have all 4 cores maxed out to 1.6Ghz at once. Battery drains faster than Asus performance mode though. As far as speeds go though, I can put my prime in stock powersavings mode, lowest power settings, n everything still moves fast n fluid. Same with heavy duty games also. There's nothing out on Android yet to really need overclocking power yet. PRIME handles anything you throw at it in stock settings. OVERCLOCKING is just for kicks really andbto make things that much faster. Not really needed. Overclocking will be better once bootloader unlocked and we get undervolting paired with overclocking. That way we can get great battery life and more power. Nothing wrong with overclocking though. I'd say if you not worried about battery life or gonna eventually be near a powersource, go for it. Android developement section of Prime. Its called VioerControl Mod. Very easy to install n setup. Works great. Everyone rooted should give it a whirl if you looking for more power or want to push the envelope.

My mistake. I'd forgotten that I'd rebooted since running the benchmarks and gaming, so my CPU Spy values didn't reflect them. I just ran some benchmarks and 1400MHz now shows 18 seconds while 1300MHz now shows 2:08 minutes.
I would still like to see that as running at 1400MHz throughout the benchmarks, so I stand by my statement that some additional tuning is required.

what Firmware specifically are you guys on????
I just downloaded system tuner... I'm running ICS, and my tablet has been rock solid (not a single reboot).
CPU0 is running around 200-400MHz, and the other 3 cores are offline (although core 1 comes online for a bit now and then.) And, my battery life is excellent.... same or better than it was with HC.
To clarify, those of you who are having reboots, are you all seeing all cores on and maxed out all the time?

9.4.2.11
Its the latest one available on ICS.
On the contrary...ever since my tfp decided to keep all cores online and minimum 425mhz speed, I haven't had any lockups or reboots.
But my battery life sucks and my benchmark scores are Still horrible.
The disk I/0 speed is horrendous (as stated in the bonnie++ benchmark thread)
Hope for an update soon

Has this been confirmed to actually work or be better? Were you the one that made that thread with bonnie benchmarks on disk read speeds or something? How much of a difference are the scores after installing the kernel modules in that thread?
First, I KNEW the thread title would get your attention. Second, i hear 95% of you calling BS, and I would too. In fact, I am still not sure what to make of it, and it makes ME think the number I am getting is BS.
Here's the deal. Got my replacement Prime back from repair, and like more than a few (read the RMA thread) I was lucky enough to get a replacement instead of a repair. I had sent in my Prime, originally received on 1/3 (shipped on 12/23... GROUND, from Best Buy, though I had paid for overnight. Serial was: BCOKAS**5153
Sent if for repair mostly for a cosmetic issue, scratches on screen border, but I had among the worst GPS compared to others I have seen, no sats indoors, maybe 3-4 outside, never a lock. After the 1/19 update (the one that we still haven't seen a change-log for) I started getting reasonably crappy GPS, LOL as in 4-6 sats inside, and 9-12 Outside, occasional locks, but nothing usable. My Wifi was decent, actually quite good I would say. Bluetooth did not dropout when streaming to BT headset watching Netflix.
The support folks offered to open the replacement and test it before sending, and I said: **** yeah: Test everything: GPS, Wifi/BT check for stuck pixels, make sure the serial shows, also check for light bleed. I was promised they would do all these things. Then it was overnighted to me.... All in all I felt it was a reasonably GOOD RMA/support/repair experience, especially in light of the horror stories, and stories of general incompetence we have seen.
New unit arrived, looked cosmetically perfect. One spot on back, it was glue or tape adhesive from assembly no doubt. Screen appears perfect, with just the tiniest bit of light bleed. Wifi is decent, not outstanding, but close to what I had. No stuck pixels, have yet to test BT streaming. GPS? I got another dead one. I have yet to see a SINGLE FREAKING SATELLITE, Outdoors or in, though it's cloudy here today, LOL (If it's so bad that clouds kill it, it's pretty ****ed up)
So that was a bummer. Yes, it's true I will probably not use it in the car (though I did use my OG that way once in a while, but I refuse to accept something that does not work. It is not in me to say: I can do without that.... even if I CAN, LOL. They are gonna get me another one, cause I am NOT RMA'ing this and going without it a week again... not for GPS anyway. If the WiFi was borked, it would be a different story.
One additional improvement. The power button on this one works correctly. I never knew how bad mine was, but compared to the 3 TF101's I had, it sucked. You never felt it bottom ot, or any detectable motion al all. It was just stiff and stuck, and I had to just press on it super hard to get any effect from it. The new one is perfect, the spring is stronger than the TF101 switches were, but at least it has a positive motion, with a solid detent, and you can tell when it hits bottom. Man, I can't believe how bad what I had was, and I had fully planned to live with it, LOL!
Okay so now for the weirdness. I am putting the new one through tests today, and among the, I ran Antutu. The numbers I got were nothing all that amazing, but the Processor speed threw me for a loop: 1600 Hz. WTF?????
Serial is C1OKAS**1793 I thought I was hallucinating. This thins is NOT ROOTED. I have NO performance tweaks, and nothing changed other than my 126 installed apps... How weird is this???
The numbers that I got were 10222, and a couple more in that range. This was running in Balanced mode. I switched it to Performance Mode (what used to be "normal" back in the Honeycomb days" ) rebooted, and ran Antutu again. Best number to date is 11089. Like I said, not up to par with folks that have REALLY overclocked, but somewhat better than my original... Anyone want to take a stab at explaining this to me? Maybe I am missing something super obvious?
Attached the Antutu result, and one other thing: The box sticker from a "C" serial number, for those who are curious: Check it: NO GPS LISTED!!!!I forgot to take a picture of my original box before RMA, screwed up there. Took dozens of the tablet to protect myself against claims of "CID" Customer Induced Damage, and forgot the box... grrrr.
GOOD NEWS: At least for the present the BOX LABEL still shows GPS. As many of us have discussed, as long as it SAYS GPS, we can still break chops to get them to fix it (or try to, I suppose) but what is with the question mark? Does anyone know the significance of that? That is kind of weird. I am pleased they left GPS spec on the box, expecially since I now have a completely dead GPS setup. I guess it's time to practice my Vulcan Nerve Pinch, but the few squeezes I gave it so far near the GPS Pogo Pins have been completely useless. Not a SINGLE SATELLITE HAS APPEARED YET.
An the Asus Support guy went on about how the Jan 19th patch was on this one. I said: as long as you see a few sats. send it along, He said (laughably) that it would get GPS performance as good as my TF101 did. Hmm. Well, to do that, it would need to start by getting ANY performance, LOL. Then it would need to work, in the car, with CoPilot live, all the way up the East Coast... Somehow, I don't see it happening. Sorry for the long post, but I was up late last night reading the huge tear down thread, and I had no energy for posting to a dozen separate threads today, on my latest "interesting" mix of features and performance with my new Prime. These feel like hand built devices.. every one is unique, LOL!
Hmm i have a C serial too and my GPS is fine. Little worse than my dhd but fine.
Get something like CPU Spy & see what it shows in the "unused cpu states" list at the bottom.
It's not overclocked at all, since ICS the Prime has 1.5 and 1.6 ghz in the kernel, however, they are both disabled. This is the only reason we currently have over clock scripts, with root we can enable these settings.

Exactly. If you all use cpu spy like lock says you will see it never enters the 1.6 state. The processor has those steps built in but aren't enabled in the firmware
People in here are funny..lmao. we already went thru this when ICS first dropped. All primes were showing 1.6ghz in the stats n benchmarks. But this isn't the case. WE KNOW THIS FOR A FACT. If you take CPU spy app n look it'll show the 1.5 n 1.6Ghz speeds disbled. MEANING YOU ARE NOT OVERCLOCKED. Only real overclock you can have is if your rooted and Running ViperControl mod or using SaturnDe ATP tweaks app or running script manually from directory /system/etc..
I was the first one to assume what all of you are saying also when ICS first came out. Then we dug in n researched further n found out this wasn't the case. It did lead us to a true overclock though since we knew it was in the kernel but just disabled. Me, I'm running a "TRUE" 1.6Ghz overclock using ATP tweaks app. Mines is confirmed through CPU spy. Plus my Antutu scores are well over 13,000. So 10,000 would be bad for an overclock like that if you really had one.
SORRY TO RAIN ON YALL PARADE BUT YOURE NOT OVERCLOCKED. Only through Root n methods I listed would you "Truely" be overclocked. CPU Spy will confirm your false claim. Don't feel bad, we thought so to at first when ICS first came out but quickly realized the real truth.
No Biggie

Uhm... No rain on MY parade. I think you misread my meaning I don't Have any great desire to overclock my ATP. Maybe later, for now I AM interested in the Kernel Module for Background I/O. Cranking up the processor does diddly when the Prime lags, and freezes every so often, especially under any type of background disk activity. 1.4 single. 1.3 ghz Multicore speeds are more than sufficient. People that overclock do so often for the wrong reasons. Why should I be cranking along at 1.6 ghz to browse a news article? If I had ultimate control I would like to control WHEN the additional core kick in, not how fast they tick along, doing a lot of nothing. I did miss your discovery that with ICS, it shows these rates. Right now I would give my right arm to know how, if you do all your posting with the prime, you deal with the cursor misbehavior in text boxes, like when it jumps to the first character position in the box, or insists on jumping to a spot and only the arrow keys will override that. And why is it "mines" do you have multiple Primes?
Edit: Also, I wasn't stating that "11, 089" was a enormous score, if you read I was stating that it was a BETTER score than my returned Prime, but not what I would expect if overclocked. I'm glad your numbers are so impressive. Maybe someday MY Prime will have a Antutu score of over 13,000! That's really fast! And that helps exactly how?
Also, since the processor has those steps built in it technically isn't overclocking to enable the 1.6GHz step. You are only overclocking when you go above that.

You are correct. Stock speeds are more than sufficient for everyday usage. Overclock just makes everything even more faster n snappier. Web pages load up faster, apps open up faster, etc.. Its not for everyone. But for me its so easy to do and has no ill effects on my tablet. I'm like why not harness the extra power. Its in the kernel anyways and newer tegra3 tablets down the line will have exact same chip but the 1.6Ghz speeds enabled Stock. I do find myself going back to stock speeds alot because I truly appreciate how fast this device already is stock and ill get better battery life on stock. I do get pretty good battery life also on 1.6Ghz overclock.
Also, yes, I DO ALL MY POSTINGs, from the prime. I don't experience the major slowdowns or lags some seem to experience. Mostly only occurred sporadically in stock browser. I used ATP settings to change scheduler from noop(stock) to cfq. It seemed to help for a while but then came across an issue before, where I never had before, where the whole stock browser seemed to just freeze up or stop loading. Before it might freeze n then prompt come up saying to wait or close. After the switch it didn't do any of this. So i switched back to noop I/o scheduler n everything has been running great for me. I mainly just use the ATP tweaks app now for quick access to overclocking. Less steps needed vs. Having to go into terminal emulator and pulling up vipercontrol. With ATP all I do is open up the app n press Turbo2 n I'm overclocked. I did try out the deadline I/o scheduler also but didn't seem to make much of a difference. Actually acted kinda funny at times so i switched back to Noop. As Noop is the best out of all of them. Its just some people switch to other schedulers based on their needs for prime to PC file transfers n such. So its really a preference thing and what you experience with your personal usage and benefit the change makes for you.
AS far as bench scores go, I just said that cuz you mentioned yours n wanted to show another form of proof you weren't overclocked. Now for the cursor jumping around, I know what you mean..lol. but I use thumb keyboard, split mode, n very use to using the arrow keys to correct anything. Yeah the cursor does jump around at times but it still goes where you want most of the time through touching where u want it. Plus copying n pasting is very easy for me now that o got the technique down packed. So all of this is working pretty well for me and not a hassle at all as majority of my post count had been made with my prime alone. Before I got the prime, I was posting from my Ipad n Atrix4g. I can type very fast using thumb keyboard. Love it. Also, I only have one prime. The "mines" must've been a typo.

Yeah yeah..lmfao but we can't enable it stock. So its still "Technically" considered overclocked since it is higher than allowed out the box. Only if you running a "true" overclock using vipercontrol mod or ATP tweaks.

I mainly just use the ATP tweaks app now for quick access to overclocking. Less steps needed vs. Having to go into terminal emulator and pulling up vipercontrol. With ATP all I do is open up the app n press Turbo2 n I'm overclocked. I did try out the deadline I/o scheduler also but didn't seem to make much of a difference. Actually acted kinda funny at times so i switched back to Noop. As Noop is the best out of all of them. Its just some people switch to other schedulers based on their needs for prime to PC file transfers n such. So its really a preference thing and what you experience with your personal usage and benefit the change makes for you.
AS far as bench scores go, I just said that cuz you mentioned yours n wanted to show another form of proof you weren't overclocked. Now for the cursor jumping around, I know what you mean..lol. but I use thumb keyboard, split mode, n very use to using the arrow keys to correct anything. Yeah the cursor does jump around at times but it still goes where you want most of the time through touching where u want it. Plus copying n pasting is very easy for me now that o got the technique down packed. So all of this is working pretty well for me and not a hassle at all as majority of my post count had been made with my prime alone. Before I got the prime, I was posting from my Ipad n Atrix4g. I can type very fast using thumb keyboard. Love it. Also, I only have one prime. The "mines" must've been a typo.

Yeah yeah..lmfao but we can't enable it stock. So its still "Technically" considered overclocked since it is higher than allowed out the box. Only if you running a "true" overclock using vipercontrol mod or ATP tweaks.

I am glad that I am not alone with the cursor thing. A bit distracting, but for the most part I use the Hardware Keyboard in the dock when doing any serious typing. Like with my TF101 I like that the dock acts as a "stand" and a cover/case. and at home I tend to do a lot of wen/newsreader browsing, and posting, as you know.
I know you mentioned that battery life seems decent when running at full clock speed (okay, we know it's technically not "overclocked") so I say "full speed to avoid being corrected, LOL! I am curious about battery performance with it running at a true 1.6, and before you answer that it is not bad, can you say for certain, as in have you tested the discharge times with the Turbo2 enabled full time? Or, if you can at least say that it's not too bad, what would you peg the loss to be? 10% or more? I agree that if I had an app to easily toggle it on/off like the build in app that prioritizes processors, I would like to use it at times.. The built in one I think does the following:
Power Saving: Runs all Cores at reduced speed, I think its 600 MHz, 700 MHz when three are active, and 1 GHz when one or two are active
in "Balanced mode" - the cores are capped at 1.2 GHz
and in Performance Mode (used to be normal mod, just to keep it sounding exciting, they changed it to "Performance with ICS, LOL!) a single core runs at 1.4, or all 4 cores can run at full clip of 1.3
Not sure where they came up with these choices, but I will bet it was only after Nvidia ran them every which way, and came to these numbers as the best compromise of power and battery life. I think the Tegra 3 SOC also controls the video brightness and depth on the fly as well. All told a nice implementation. I still see lags occasionally, and games like Riptide GP freeze in a "Stutter Frame" kind of lock, till I exit to home screen, and resume the game, and it's good again.
Anyone else get that?

See I don't even have a dock n typed all that with no problem. Thumb keyboard makes typing so easy n fast on the prime. All I use is 2 thumbs to type n can do it very fast with the split keyboard mode.
AS for battery life if you ever ran the built in performance mode full time, then you will know it drains the fastest out of all modes because its running the higher speeds. Now with 1.6Ghz it drains about the same or a lil faster than performance mode. I've noticed lately I've been getting battery life even better than performance mode on my overclock. For the quick implementation of it that's easy. It can't get no easier then this. Check this out..lol. if you rooted, all you have to do is go into prime developement section. Go to ATP tweaks thread. Download and install ATP app into prime. Then open it. Allow superuser permissions. Then just press the Turbo2 tab n bam! Now you St 1.6Ghz overclock. The real one. You can use CPU spy to confirm that 1.6ghz speed is enabled.
hen if you want to disable it, just reboot tablet. Then whenever u want. All u have to do is open up that app n press turbo2 tab. There's a turbo1 also n that's for 1.5Ghz.. There is a step to do a more hardcore overclock to where you can run ALL 4 CORES @1.6GHZ at the same time all the time. Of course this burns up the battery the fastest. I doubt u ready for that yet though... lmfao just take it slow..lol use the regular overclocks. Get ATP tweaks app in developement section.
For the games, I don't have no stutters or freezes even on stock speeds.
Ok so im rooted and overclocked and was using setcpu then decided i wanna try something different so i tried system tuner! When i checked the cpu it said that one of the processors are off line! Then i pressed the info button and sure enough it says only reading one! So i went through the settings and found force both cores online!
Since then i have no lag and virtually no checkerboarding on the web! Anyway i was just wondering if im the only one who noticed this and maybe it could help those who say that they are still getting lag on they're roms using dag's kernel!
Also i hope devs will notice this thread since i can't post there yet and take advantage of this how ever they can!
Now don't quote me on this but most likely the second core only turns on for processor intensive activities such as high graphics games or multiple programs running at once. I do find it hard to believe that it would be totally disabled. Most likely this is done to conserve battery.

Okay if this really is the case I could also see at&t disabling the second core totally to save battery because of lte but i guess it will take a dev that has more experience with how qualcomm's multicore cpus work in android. report back with differences in battery life like how much faster does it drain now that both cores are forced on.
if you want both cores on click on boot settings and enable force all cpus online. that heats up your phone and eats more battery though+I do not see any benefits doing that.

Same, but having a better processor helps. Like exynos. I bet once we update to ics if it ever happens, the differences will be only minor between processors, as it runs so nice.
Got system tuner pro, and it shows speed bars on both cpus running? I didn't change a thing?

Not entirely true.. the Galaxy Nexus has a kernel governor that turns one core off when the SCREEN IS OFF, but not when the phone is being used. Multiple kernel creators have since implemented this into their kernels. It is called "hot plugging" and it just turns CPU 1 offline when the screen is off and turns it back on when the screen is on

Just checked mine, rooted and OC with DaG's 0.1 version (first version). When I looked, it said the second CPU was offline. Changed it to online, we'll see how that impacts battery life.
How much of an advantage is smartassv2 anyway?
I just tried this with system tuner and both cpus were working but wone was of and on and zero was always on.
I am running stock rooted. If you just sit yhere and watch it you will see tje sevond core fires and shuts down alot.

Same for me (CPU 0 on, CPU1 off, most times) and I'll say I have noticed no real changes in functionality (speed, rendering, etc) or battery life...
I guess jury is still out or is this a YMMV kind of thing?
I installed system runner and watched the cpus. One was on and the other kicked in periodically
Mine said it was offline as well. Forced it on and am not noticing any difference in speed or temp.
Ill leave it like this to test it further.

As far as I know yes you must have super user permission to alter such system activities
I don't know why everyone is in such a rush to force the second core online, it turns on and off when it needs to.

I've read on several ROM forums that only certain apps utilize or dual cores. go to sys/devices/system/cpu/cpu1 there is a file there. When using one of the above said apps it populated cpu1 with freq folders etc, changes that one file from 0 to 1 enabling it. without one if these apps there is no freq tables for cpu1.
****my question: using Linux and cpu i ran speed tests. Over 70 tests in total. There is zero performance difference in using one app versus another versus cm performance cpu menu. I understand how it looks like two cores are only utilized from certain apps looking at the folders. However it does not change performance at all. Tests show same speed any way to control cpu. Also feels the same. Is there really a difference our is it monkey say????
Also in my tests i found using "VR" versus sio or noob or cfq to be the fastest. I didn't feel a difference however changing i/o setting.

Their are claims that Intel’s internal handset testing has shown multi-core implementations running slower than single core, however they did not cite any particular chip. If you take a look a lot of handsets on the market, when you turn on the second core or having the second core there [on die], the [current] leakage is high enough and their power threshold is low enough because of the size of the case that it isn’t entirely clear you get much of a benefit to turning the second core on. In some of the use cases they cited, having a second core is actually a detriment, because of the way some of the software engineers have not implemented their thread scheduling properly.......
That being said, one could argue the concept that a single core chip, running a slight overclock, would produce a far better result, than a dual core application. But again, thread scheduling detracts from any governor efforts anyway...IMHO....g
Hum. I would have to agree then that in our case and in my tests dual core doesn't help nor hinder performance results but does appear to reduce battery life. Now these are my tests using two different programs to test performance and using combo of setcpu/system pro/Cm10 performance built in/Tasker to control cpu. I have done enough testing to know that on cm10 roms dual core, or so the sys files indicate, is of zero performance upgrade and appears to drain battery faster.

Yes ...I agree with your findings.
I suppose it's safe too say then, when using the AOSP rom source, within it's normal configuration, that unless development is done beyond the current schedules, the stated performance is well ....overstated ??
Of course , CM is in a constant state of change, and I suppose that after they are finished with the functional repairs, they may focus more on the kernel.
I'd be very interested to see your same tests against another kernel, say flappjaxxx latest JB build.
I do know that he, and several other developers have made some great improvements to the source kernels, and although there will likely always be bugs present, after running my own evaluation of them, the governors are functional and do make at least a perceived difference.
But as you stated, albeit at the cost of battery life.
I choose not to overclock, as I feel that the marginal reward , as proven by your testing , and by testing from several reputable sources, is simply not worth the risk ...g
I agree Greg, i will test other kernels... Samsung ROM is probably the only one i won't test... I also don't overclock, i do under clock at work and screen off using Tasker for battery life. That does help greatly. I'll post back after testing different kernels tonight.

Excellent....
And I suppose, since this is the Premier development site, that it would be of great value to the community if you could perhaps publish your results here ?
These aspects of the android OS have been of great interest to me for some time.
Without doubt, many other users would enjoy this information as well in forming their decision regarding roms, kernels etcetera.
Thanks to you, for your inspiring thread. I look forward to the forthcoming information ....g
Ok with out posting tons of pics i tested all available kernels (new). Results were the same. No real difference in single core versus dual core...
The following pics show how to know whether the second core is online or not and my results and how i tested this time around... I was more through the first time but results the same.

I am posting pictures for first time hope this turns out.
What do you use to disable the second core? Read this with some interest. Would like to try this with ics Rom. With oc'ing fRom 1.56 to 1.72 i see a consistent jump of 300-400 in my antutu scores. Currently on flapjaxx ics b4.
I know it is just a score, but is your score indicative of the cm builds? It just seems really low.
Here is my 'stock 1.56 speed' with ondemand governor. Want to a get a single core sample.to compare with it.
How interesting ....
I can say that both of your posted results lead toward our initial assumptions, that indeed we are seeing a consistent draw against the systems cores with little or no improvement upon activation of the second core.
Some Time ago, shortly after my note arrived, I began some simple tests with low speed dual core activation. My thought process was simply this.
Slow speed dual core operation (both cores running in the 650mhz range ) would ideally produce a faster process response.
My initial results were favorable, as I had a noticeably quicker device during screen transitions, and even in several multitasking functions.
I even went so far as to create a small script to handle this function for me. I'm no developer, and ultimately I didn't possess the programming skills I needed to complete and implement my script into an actual, flash worthy modification. And based on what we are seeing here , the results provided would indicate that my attempt is flawed due to chip current leakage, if the cores are allowed to ramp to high, and perhaps even the use of improper source schedule interference.
I'm so busy these days, I simply haven't time to explore the low speed theory further at this point.
But perhaps with your test bench already set, a simple test using my concept could be carried out??
As we know, CPU [current] thresholds are plagued by voltage bleeding at maximum CPU frequencies, but the thought has just occurred to me that [current ] bleeding is highly controllable when the CPU is driven at lower voltage inputs. And too combine a reduced frequency with reduced voltage over a multiple core platform, could, or should balance the loss and equal the output levels.
Are you up for another test ??
If so ....I suggest the following parameters.
Core "0" at 600/700 MHz
Core "1" at 600/700 MHz
Governor at "interactive "
Voltage at "-24Mv"
Then we'll see if the theory holds water.
P.S. thanks gents, I'm enjoying the heck out of this thread ......g
Mad383max, look at your folders from my pics to tell if two cores are running. Typically on after market roms one core is running until you enable the second from other software like from my pics.
Will test at lunch. I like this lower voltage idea. If i were a betting man i would guess with speeds you proposed and two cores i would guess similar to higher results. Let's see....

I have to reflash ROM so pics might be a little awhile. I messed up some things and somehow lost my Google account. reflashing gapps and ROM didn't fix it.
Anyway results were 2600 something at 700 both cores underclocked 25... Slightly more than half of normal speed at slightly less than half clock speed... For kicks i tried 1.5 clock speed undervolted 75 (most my phone will go without lockups) and got 5k results. Best yet.
You are on to something. Less voltage = more speed. I now need to try single core undervolted. Give me couple hours for pics etc.. Got to get phone working with Google again and spend time with wife. She hates me on the phone.

No worries Troy. ...
Take all the time you need.....
I do appreciate the excellent testing you have undertaken. I know that the results are going to benefit the community.
And i am highly intrigued by your first run under the parameter set you've chosen...
It's leading down the exact path that i suspected. ..
I'll talk with you soon. ...g
A few additional items that I have failed to consider during my testing, could weigh heavily on our testing results and should be considered during testing.
They are, battery power levels, charger connection and type....(wall/PC), and rom power save levels.
I do know that the android OS will adjust itself during varying power levels, much like our setting the CPU to UC/UV settings, only on a much smaller scale.
I feel its important that we are able to control the input levels in the following way...
Battery to full charge, with no charger connection, and if the cable is needed we use a non powered port. Next would be controlling the rom power settings if the rom contains them, as found in most GB and ICS builds.
If these baselines are met, we should be able to greater rely on the mark scores we are seeing. These variables could explain why we continue to see so many peaks and valleys in scores when two users share the same builds, on like devices.....(speculation)..
Additionally, are we able to control the background processes to the extent, they will remain constant for testing?
Sorry for the rant.....Im just concerned about the ability to quantify our findings once testing is complete.
Ive started some tests on my end as well, and certainly do not want to give you the impression that I expect you to do all of the work.
After all, you did ask first....lol and I feel like Im dumping this effort into your lap.
And please forgive my pathetic punctuation in this post, as my keyboard of choice decided to fail tonight....g
Battery does effect performance greatly.... Also noticed none of the apps to test are very repeatable. Fluctuation seemed to be about 100.
Having issues up loading pics from phone, I'm away from laptop for a few days.
In the end i found -12 v single core to provide the best battery and performance that was equal to dual core. I tried over under voting many differences.... over voting did nothing, under voting a little made small preformance improvements. I believe some of fluctuations are related to app, battery, etc.... In the end it's too say dual core has no speed improvement. I would be cool to test an app that it's specifically for dual core. I am better off without the second core speed is same anyway, and battery is much better. There is definitely voltage leakage..
Let me know what y'all find in your tests....
Sent from my SAMSUNG-SGH-I717 using xda premium
Outstanding !!
I appreciate the hard work !!
So it seems we are better off using the note running a single core and about 12mv under volt.
And I'm of the belief that our second core is rather pointless...unless it can be proven that the second core is absolutely needed to perform a function.
And so far, I haven't found anything I use that requires activation of the second core.
I'll continue my tests, but the way it looks now, Intel is right, and Samsung pushed a dual core chip to this device for nothing more than a market share increase. As it is quite clear that the device does "not " need it to function well, and at a Very respectable speed.
Now we have a quad core version, and I highly question the motivation behind that move, beyond marketing as well.
These statements may offend some, and folks will certainly disagree, but if you want a great running device and great battery life, you need a single core chip ...IMHO ....g
Agreed Greg. Someone will get upset when they do thirty own tests and realize what we see, and what you said, good marketing by Samsung. Numbers don't lie and i did tests as controlled as possible. Even my battery shows in the picks... A true second useful core would have easily bested the single core results. Plus undervolting tella the bigger story...
I must say though. It had been very useful.. My battery life is so much better now!!!
For me the only true performance gain had been from v6 supercharger.

Fyi: same exact results using cm9 versus cm10. Neither ROM benchmarks faster than the other as of 9/16 cm9 and 9/15 cm10 builds. Dual core zero performance upgrade.
Tried quadrant again and result very up to 20% back to back so that app is useless to me.
Can someone try a Samsung based ROM. I'm curious add to a difference in roms. just use antutu benchmark and set cpu however you wish to whatever you wish just report cpu clock speed, type of test, and results
