Undervolting and profiles.
I have tried a crap ton of different undervolting setting, but none work
Also the profiles in set cpu don't seem to work for me. I have a few of them set and it always sits on the top one I need some guidence with both please!
Another thing my xda premium app isn't pushing my notafications yes its set

Undervolting is a delicate process. It takes time to find the max undervolt that is stable. With that being said, try undervolting everything by the lowest amount which is -25mv. Check to see if that is stable. If so proceed to go further. Remember lower freq will typically undervolt farther than higher frequencies.
As far as profiles go your probably not using the priority values right. The higher priority is what determines which profile setcpu uses. So for instance if you want a safeguard against overheating, you could set the profile for when the cpu goes above 55C to throttle the processor way down. If you set this profile to 100(max) it will overide all other profiles at 98, 99, 75, 50...etc. Also this may be obvious to some but be sure to tick(enable) the profiles button. If thats not ticked then it doesnt matter how many profiles you have set up. It simply wont use them.

When I was on alien rom, I tried 25 on all and it restarted after like a minute. What worked for me was 25 25,50,50,75,75,100 fromm bottom to top. I tried it with cm7 and total no go lol
Lemme tryi 25 on all and see what I get and I didn't know that. They all werent working, so I set them all to 100 lmao, I understand that now

Glad your getting some results. If it restarts even once it means at least one of your undervolted freq isn't stable. With your settings I would wager its in the uper freq considering your undervolt in the lower freq isn't too extreme. You might try decreasing the undervolt for your upper freq to -50 -50 -50 starting at the top. Might help to stabilize bc higher freq just require more voltage. If that proves to be stable continue trying to reduce the lower freq as much as possible. Mainly bc if you set your profiles right(screen off is the most important really) your phone will spend the majority of its time on the 200mhz freq. Thus the more undervolt on that freq should theoretically give the most benefit from undervolting. This is just all from personal experience. I'm no guru. Just spent way too much time adjusting voltages on phones . And of course having the upper freq undervolted as much as possible cant hurt either.

First off, regarding SetCpu and over / undercloking, dev has said it'll only underclock/overclock ONE core at a time. It's a bug and he's working on it from what I understand. If both cores are needed to be in use at the same time, no over / underclocking will be applied. Secondly, profiles work as they should in SetCpu, so that's a problem on your end. Third, the undervolting can't be more than 100mv differnce between jumps. See screen shot.

Yea Im skeptical about not setcpu not having support for dual cores... Did some searching on the net and couldnt find anything to support that. As far as not the tegra 2 not being able to do over 100mv jumps. That's not true. My lowest frequency is 600mv (-150) and my next frequency is at 750mv. That's a 150mv difference right there... And I'm completely stable. Its entirely dependent on your processor. They are all different and respond differently to undervolting. You just have to find what works for you. Generally though the lesser the jumps in voltage will give you more stability.
a good kernal helps too im useing faux123 v2.0 0C1.3 its undervolts quite well

I had my S2 set to 1.6GHZ and noticed very little battery drop compared to 1.2ghz (stock) so now I am just wondering if it would help me save battery if I set it to 800mhz?
Anyone know if this will help?
And for some reason SETcpu only detects the S2 as 1 core. So hopefully thats just an error and I hope I really have a dual core phone.
Which kernel are you using?

Changing CPU speeds will not help you save battery. Undervoltaging (UV) will, however. UV only works on certain kernels, and you MUST know what you're doing before attempting to overclock and undervoltage simultaneously. Read up OC/UV guides around the forum to know more and the recommended speed/voltage pairings.

I'll be staying far away from that then. Thanks!
of course underclocking will give you a bit more battery life. even if you don't undervolt.
underclocking it to 800 simply forbids the processor to go up to 1 or 1.2ghz and it doesn't need as much power as in the higher states.
a normal desktop cpu also gets hotter if its overclocked with its stock voltage. But if you crank up the voltage too, to keep it stable it will get even hotter.

That may be true, but higher frequencies have a higher power draw, the phone at lower speeds should be able to manage with whatever the task is, assuming it's not a extensive app. If you're not a power user you don't need the phone to be clocked at the max freq, you can lower it and you see minor changes in battery life. With dual cores task are handled must better so 1.2ghz+ shouldn't really be needed, TouchWiz can't be as bad as Sense, where you actually need it to be clocked higher.
Oh man, Undervolting is OK but why would you Underclock a CPU? Now don't tell me it's too fast, don't need that speed in real world, you won't notice any difference and etc..If you are gonna Underclock it why did you purchase it on the first place?
Besides, that article said it all.
Regards.
For me I think underclocking + undervolting does indeed save battery life.
What I mean is that in my sig '1.6Ghz - 1325 mV' an at '800Mhz -950 mV' you see a difference of 375mV which I think can save your battery life for a couple of good minutes + 800Mhz is enough for my needs along with playing games (Only a tad slower at loading).
That's not necessary true. Yes at a higher frequency the task would complete faster but at the same time the processor with use more current and or increased voltage at the same time. That's why cpu's level up and down. Otherwise why not have the CPU set at 200Mhz-1200Mhz instead of 200-400-800-1000-1200Mhz.

Please set your computer on fire and never return to the internet ever again so it doesn't have to be filled with your stupid statements.
Also yes underclocking saves battery, anyone who says it doesn't is dumb, you wanna see for yourself? set your phone to 1.6 GHz all the time, according to you people this wouldn't significantly drain the battery any more right?
Undervolting saves slightly more battery than underclocking.
Also why would you underclock + undervolt the phone? Because it saves battery and you won't find any noticeable performance gains between 800 MHz and 1.6 GHz.

Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)
So I'm interested in undervolting using the stock CPU freq's, and I'm going to be using setCPU (obvi).
So, first question: Even if I want to use the stock frequencies, do I have to be using the OC kernel (0.2.1/1.45ghz at the time)? And then adjust the max to 1000mhz?
Second, I started up SetCPU and whenever I go to the voltage tab it forcecloses. This happens with both the stock enhanced & OC kernel, and I've tried fixing permissions to no avail.
All I really understand so far is that the end result is a table of CPU frequencies and linked voltages. I've OCed the hell out of desktops, but I'm lost here.
I'd just like to know how to get from starting up setcpu to ultimately popping out that new voltage/freq table.
I do apologize if this seems kinda stupid, I'm just trying to exercise caution lest I demolish my phone's innards. I've done it with many an intel.
If you just want stock frequencies, then there's no need for a custom kernel. I guess in that case, you could just use SetCPU for undervolting & profiles.
However, if you want overclock, you'll need a custom kernel.
If you're going to be using a overclocked kernel (i.e. the new Faux 1.45 GHz), then you will need to set the max to 1.45 GHz, and make sure SetCPU is set to start on boot; other wise it will stay at the stock clock speed of 1 GHz... So i guess if you only wanted the OC at certain times, you could set the max speed manually, only when you want to, and not select to start on boot.
I haven't really had any success with undervolting yet... always crashes on me & reboots. The best thing to do is make sure "set to boot" is not selected, when testing your undervolting, other wise you could get stuck in a loop, with the phone crashing every time it boots and tries to apply you undervolting values. I'd start at -25 for each and work from there... stress testing each choice with a benchmark app to make sure you wont reboot... if it reboots, then you know your undervolt was to much. Also remember that you can not undervolt more than -100 between each frequency, otherwise the undervolting will not make any difference.
I really like the profile options in SetCPU... you can set the screen off frequencies to the lowest two, that way for whatever reason your phone isn't running at full strength while your not using it. Also, you can set frequency speeds at custom defined battery levels.
Hope this helps somewhat.
It's unclear to me why it force closes. This may be a rom incompatibility or a SuperUser issue? I assume you've tried uninstalling it and reinstalling it? Updating your SU app? Try flashing to the latest Aura rom?
A few quick words about SetCPU:
1. When you first get started, do not set to "Set on Boot" in case you've undervolted too much and it crashes when applied. You can always check it later once you know the voltages are stable.
2. Between each frequency step there is a maximum of 100mV step off. Anything greater than that it defaults to native voltage. I think this is a Tegra2 issue.
With that said, undervolting is simple: simply slide the little slider on SetCPU to negative values. How much you can under-volt largely depends on your particular hardware and it is inconsistent across all Atrix's. My voltage table is as belows:
1000mhz: -50
912: -50
750: -50
608: -75
456: -75
312: -100
216: -100
I, however, did not test the limits of my phone. Many people will slowly increment the voltage lower until they start to get resets, and then they'll move it back to find the lowest stable point.
It has, however, been well established that minor undervolting improves battery life and diminishes heat generation. Excessive undervolting may actually hurt battery life. You can look around on this forum regarding the data. However, reasonable undervolting will improve battery life.
Thanks fellas, this helps A LOT.
I was so afraid I'd get 17 responses of "You're such a noob. Stop cluttering the forums" etc etc
At this point, I think that the problem is, for whatever reason, the FC when I tap the voltages tab.
I'm on the newest Aura (1.2.2.1) newest enhanced stock kernel from Faux123 (0.2.1) and the newest SetCPU (2.4). I'll try updating my SU (though I believe I did that right after I flashed.
I'll reintall SetCPU and report back.
Until then, THANKS BUCKETS fellas. I really appreciate the info and advice.
UPDATE: May have found the problem. When it first boots up it prompts to autodetect freq's or choose them manually (or something like that). I was afraid this would actually alter my CPU clocks right then and there and so I hit manual detect, saw something that said Tegra2 etc and clicked it. I just now hit 'menu' and set it to autodetect, tried the voltages tab, and no FC, so I think that's solved.
Thanks again for all the info guys! I'll start experimenting and let you know HOW LOW I CAN GO (ha).
You guys get force closes due to kernel problems. You have to ask your developments. There might be something wrong with some of your cpu voltage drivers. So yeah that's why just a tip. Only overclock when you're playing some high end game. If not stick to normal. If not your phone might get overheated and damaged

It's cool bro the problem was totally a user goof by me. I kind of agree with your OC philosophy though, primarily because 1ghz with this proc an RAM seems ample and I don't do much gaming.
Real quick:
When undervolting, should I do it one freq step at a time? Or can I do ALL of them at say -25, stress test, then adjust? Also, what's a good stress test that'll force the proc to hit all the different freqs instead of just the max clock and then the minimum when it's idling/the screen is off?

Id start at -25 for all. Setcpu has a built in stress test under info, I think. Could also try a benchmark to test it. As general rule if thumb, then lower frequencies can be undervolted more, while the higher ones take some tweaking... I can't even do -25 on my 1000, b/c ill eventually get a reboot, maybe not right away, but eventually. Every device is unique when it comes to undervolting.... just remember to not set the undervolt part to auto on boot, until you get it somewhat stable.

Got it. I figure that 'set on boot' checkbox is basically a wedding ring ha. Thanks for the advice and insight my friend.
Also (as I run my first stress test with -25 across the board) if I get reboots early on, should I assume it's the higher voltages and that I should back off on the fast end of the clocks?

When testing each frequency just set your min/max mHz to the level your testing i.e. min/max=1000. UV and stress test at that frequency and if it's stable, move to min/max=912 and so on.
FYI, my MHz might be different than yours, I'm on the stock enhanced.

That makes perfect sense- limiting the max during the stress test. Thanks for the tip bro I really appreciate it.
Are there any benefits for doing so and if so, what are the best sets for it???

yes battery life can be improved significant also with the overclocked kernal you need higher voltages to remain stable.
Just to make sure you know you need to have a custom kernel flashed such as faux's kernel to do either of these things.
As for values it really is a by phone thing some people will be able to drop voltages quite a buy while other can't drop at all typically though at lower clock speed voltage can be drop much more on my phone at 1000mhz it has a 50mV drop but at 216 its a 275mV drop

Okay, I understand you. At this moment I have the 1.3 kernel from faux. I know some people said that certain voltages can crash your phone, so I wanted to make sure I had help before I messed something up.
*EDIT*
I have it set to 1.1 mhz
Sent from my MB860 using xda premium
Use SetCPU. A good way to undervolt is to decrease all clock speeds by 25mV to start. Play around with your phone and games to see if anything freezes up. Then keep lowering 25mV at a time until you start seeing instability, then put it back up 25mV to where it is stable and you should be pretty good.

Quick tip: Before you start messing with voltage settings go to SetCPU's main screen and press Menu>Safe Mode Instructions>Extract Zip.
I hardly ever see this mentioned, but if for any reason you select "Set at Boot" when testing out settings and get stuck in a bootloop, flashing the zip that is extracted will put you in "Safe Mode" and none of your settings will be applied, allowing you to correct the unstable ones.
Thank you all for your help. I have the voltage clocked at 1125mv from 1200mv (1200mhz) mv and 500mv from 750mv (216mhz). Everything seems to be running smoothly, but haven't been able to run an appropriate test for battery life yet.

Hey guys I know this was already asked but still i didn't found an answer . Is there anyway to incrase your CPU limit . Mine it's at 729 . If i set it to 747+ it will block and reboot . So is there a way to incrase it ?
I'm using Kernel roq XIII+ .
The cpu in this phone is what I believe to be an Arm v6 Adreno GPU. The max overclock we can get on the phone (whilst stable 100% of the time) is around 748mHz. I've seen people with 806mHz at certain times using Rom and kernal mixups, like once when I used PerfectPeso and Francos Kernal. Weird occasions...
I'd say max for speed and so on, go 100mHz or around that for lowest, and 728mHz for highest clocks.

Dont underclock below 448MHz. All frequencies below that have the same voltage so its pointless as power consumption will be same. If you clock too low, it'll take more time to come out of sleep. And don't overclock above 748Mhz. If you consistently clock above 748, there is a high chance for kernel panics. I know a guy who did so and now even 748 isn't very stable for him.
That is not totally correct. 122 MHz uses a lower voltage than 245-480.

However it's slow and there is a reason why LG chose not to you it by default

You mean in the same manner LG chose to use crappy default kernels with defective touchscreen driver, or a crappy GB firmware, yes? Sorry but what LG does or not does is simply irrelevant.
And I did not tell anyone to use 122 MHz, but it is possible and at least with screen off can't hurt. If you don't like it don't use it! But don't act like you knew better.

I use 480-748 with no problems on my current rom (Lupo's CM9 test), if your phone is unstable or simply reboots then you may wanna try another rom/kernel
With popdog's Oxygen rom (version 2.5 at least) I also had no problems with the same range.
See what CPU we have it's one 600 very stable. if you are clocking it more it will heat up that's why it reboots and some time it freezes. I would suggest you you to use it at 600 or you can go little upper side. But if you really want to over clock it high then it has some issues. There are extreme heat. battery drain. reboots. hang. it can break you sound and VGA chip...so do it wisely. in 600 LG P500 is very good.
Every combination will be different. Some CPU will handle higher clock speeds than others. The manufacturer only lets it pass inspection if it exceeds their minimum specs. That means there will be some that can handle more.
You will find out with use.
Your kernel and governor will also make a difference. So will the rom depending on the tweaks used.
Do you really need to clock it faster than that? The faster you go, the hotter you go, which shortens the life of the chip. Heat is the enemy.
