Hey, new member on here but I have been lurking a while. Just rooted my Mega 6.3 and have also installed SetCPU for Root Users. What speed is safest? I have maxed it out on both sliders but not really sure if its OK!
Thanks in advance

Ya man that's no problem...i run my mega the same way, as I find its much faster and smoother at max clock on performance governor. Just so you know, this is not over clocking, since your on stock kernel you cannot actually over clock a stock kernel..i am putting together a custom kernel that you can over clock, I'm just finding the sweet spot, and will be releasing it soon. Prolly clocked around 1.9 or 1.85 ish. So far in my testing it had the mega running extremely fast.

Wouldn't having your CPU running full steam be a problem ...heat issues and instability .. The min shouldn't be the same as maximum... And performance gov does what exactly.

No...not at all...In fact the note 3 comes stock with its cpu at max clock and min clock with an on demand governor, so anytime your doing anything really your running max clock. The mega runs much much cooler than the note 3 so there is no issue, not to mention these are only the max recommended clock speed by manufacturer, which are typically under estimated between 25 and 50%.
The only real factor that could cause any problem at all is heat. If your device were to overheat to some extreme then you could have a problem but other than heat it's perfectly safe, and very effective for performance increase. Not to mention there are typically 3 protocols built in to safe your device from any harm from overheating, a screen dim, reboot, and shut down. And I'm only talking about setcpu on stock setting it at max clock for stock kernel...then we get into over clocking which if you under clock will know, the only downside to over clock is diminished battery life but it's a trade off for performance. But to be honest I only lose about 45 mins on my note 3 at max clock of 2.3 ghz and about 30 mins screen on time with my mega at max 1.7 ghz. But I have several devices the i either carry or develop for and each of them I run performance gov and max clock speed, and have never once had a problem doing this on stock kernel and always see major improvement in speed. For instance my i9205 megas probably saw the biggest speed and smoothness boost from this setup of all my other phones and note tablets. Your mega will run nearly identical to a note 3 fir transition animations and browser loading by sticking at max clock. And I still get 4.5 to 5 hours on screen time a day minimum.
Lastly, governors...In a very basic definition (I suggest you google is schedulers and kernel cpu govs) are basically the controller commands for the cpu and gpu. On all of my devices I run max clock speed for both min and max set to the highest, with performance governor. The performance gov literally just keeps the cpu at max throttle vs varying the clock speed. The scheduler (like cf, deadline ect) controls the flash memory aand the optimal io setting varies by device...of my devices each have different in schedulers that they run best on, just test your device with each.
Now it gets tricky as stock usually has 3 io schedulers and about 6 to 10 governors. Custom kernels on the other hand will add all kinds of customized govs and io controllers. Just google this if interested, will make a world of difference for the performance on your device.
Mega
Oh I know been over and underclocking and io scheduling and governing for a long time I just never used performance because I've seen problems with it in the past for others. I was just curious of what you knew about performance gov. And to see if I could get a different perspective from you which I did so thanx for that. With my under clocking it seems I still get great performance and battery life, probably isn't even really that much better but I will consider trying out some overclocking on the mega.Overclocking was always good to me with my other devices.Just started under clocking for some reason lol cheerz:beer:

Shayne...what issues have you heard of running performance gov? There's actually a bit of evidence and school of thought that running at optimal performance is better for the hardware as it more efficiently performs tasks in a shorter period of time. Plus the fact that my devices all run cooler once the initial burst happens...typically around 8 degrees lower than when using a fluctuating gov. If you research on xda performance gov you'll see plenty of info. But the difference in performance is actually quite a lot to be honest. This is the same effect that intel use when implementing turbo over clocking...it performs said function faster allowing for regulation of temp and other parameters quicker than varying the clock to try and run the same task which means more strain on the cpu and higher temps. While it may sound and bit backwards at first once you run it at see what I'm talking about it makes much more sense. But on stock kernel unless you have and faulty device there is absolutely no issue or danger whatsoever...your our more than likely referring to running max over clock on a custom kernel that exceeds the threshold for a given hardware and causes overheating and in turn some other issues.

Tbh you really don't even need to do this, as without a baseline for what is standard or what is nominal for the mega and the krait 400 architecture you'll see a number with zero context. A better number to follow is your battery temp which is displayed in set cpu under info amd batter stats...that will run while at max clock around 87 degrees which is extremely cool. Highest I've ever seem mine is 91...whereas my note 3 without max clock is 95 lol. Max clock on the mega is extremely safe especially on stock kernel. Even my custom kernel I'm test running at 1.9 ghz only hits 94 degrees. Just fyi

I am new to all of this so I am just starting out. All I have done is root the phone with Odin and started messing with the cpu speeds.
How can I take the processor beyond the 1.7ghz? What level is safe etc?

You can't take it past 1.7 ghz...at least not until I release my custom kernel. As of yet there are no custom kernels for the mega. But to be honest if you set it up how I told you...Max clock and performance Gov with cfq setting for the io the mega will be extremely fast and smooth. As for safe over clock levels...I'm currently testing my kernel on my mega as we speak and it's running 1.92 ghz but I have to do more testing before the alpha release.

Some of you may recall my similar thread for SetCPU...
http://forum.xda-developers.com/showthread.php?t=1321136&page=8
Well I recently switched over from SetCPU to VC and am quite happy with it... figured I'd make a thread for users to share their experiences with the app...
First a few ground rules...
You must share the following info...
Kernel, Rom, Paid of Free version of the app, Screen on time, and all your settings in the fields in the app. Also include your average battery life on a full charge and if you're on the stock battery/charger or not. *Pics are encourages and appreciated.*
my config is in my sig...
I'm also using the paid version of VC which is awesome and I have undervolted quite a bit.
*The following voltages are being tested for stability*
Noop + Ondemand
100mhz-1200mhz
1200mhz: 1200 mV
1000mhz: 1050 mV
800mhz: 950 mV
500mhz: 850 mV
200mhz: 850 mV
100mhz: 825 mV
GPU 114-267mhz
114 @ 800
267 @ 950
I average about 24hrs - 26hrs of battery pending my use with about 3hrs of screen on time.
Purpose of this thread is to exchange information on how to get a better performing and more battery efficient phone using some tweaks.
P.S. Remember all phones are different and you should NEVER expect someone else's config to work for you. The purpose in this is to get a base line for tweaking and help out users with little or no knowledge about getting good battery life and also how to make their phone faster/more efficient.
Thanks
Nice to see a similar thread for the i777 model running Entropy's kernel as well. As I always say, caring is sharing lol
Crack on mate. This kind of info makes it so much easier for new users to get started with undervolting without having too many trial and error headaches.

anyway here they are! i cant wait to see what others have!
A question: Do you use both VC and SetCPU? Won't the governor setting in VC clash with the governor settings/advance settings and profiles set in SetCPU?

You'll find that you can run lower voltage on a forced single stepping than you can when the CPU has several steppings to choose from. For some reason the CPUs don't play well if you go to low or if it has to make to big of a jump between certain steppings.

I no longer use setcpu and I do run quadranrt or antutu usually. pro version has no such stress test, but if you ask me... one should be implemented in a future update.
What amazes me is the difference a rom can make. Running Siyah 2.6.11 with the exact same VC settings (the ones in the OP of this thread) on CM7 nightly and ShoStock 1.9.1 and running Quadrant the results are about 1000-1500 points higher on cm7 nightly. From a user feel perspective they are both smooth as butter but I wonder what makes CM7 so much faster on the synthetic benchmark. Has to be a storage I/O thing or something. Battery life seems to be better for me on ShoStock though.

I used to test steps individually but again what's stable individually might not be stable with all the other steps included. I usually will quickly run through apps like mms, email, video, web, and also run a few BMs like antutu
A useful app with all the bells and whistles, with the capabilities of almost every utility app available is ROM Toolbox. I use it to edit voltage, CPU frequency, build.props, etc. Look into it if you're tired of trying hundreds of different programs for different features.

Why my phone does not support OC ?
Non OC kernels and roms work just fine but with OC always bootloop.
Is this hardware based or software based restriction? Anyway to bypass this?

There is a maximum your phone can overclock to before it begins drawing too much power for it to handle. Maybe you are trying to push it too far?

Or maybe you should try using a kernel that can actually be overclocked...
Sent from my Desire HD using XDA
Well, I take it for granted that you have the right kernel with OC support.
Once you have the right kernel -generally speaking- and one application that manages the OC (or the terminal itself) you've gone half way long, since not any Cpu is the same, even if it should be, according to the manifacturer.
The naked truth is that Cpus are built in order to match the standard clock to which they are set, while some of them can bear a huge overclock. But the matter is that you have got to play with undervolt and overvolt, to get the right tuning.
Most patched kernel support a uv-ov fine tuning and each of us must look for the right tuning for his own device.
Always generally speaking, you can look for "smartreflex technology" to get what it is (it something by Texas Instruments).
So for example, my gio stock clock speed is 787 (actaully runs at 800 though on stock roms). Some people can overclock it 940MHz stable, while some people (like me) can only stably overclock to a mere 844. One tick over to 864 for me, and the whole thing craters and reboots like crazy.
Im using Cyanogen Mod 9 and the kernel does not support Over/Under Volting, only CPU scaling. So if i got a new kernel that supported everything my one does now like init.d, scaling, and all of that good stuff, if i was to overvolt, would my CPU handle a larger overclock? Or is this simply limited by the variations between cpu's when it was built?
Well, I am neither a professional coder nor a CPU manifacturer but, according to my one year experience at Nokia n900 Italia forum, which I think could be referred to any arm cpu, even if the phone runs android, the differences between the same CPU are huge band the only way to get the best id to try a lot.
For example, my n900 CPU standard running at 600 MHz, could not bear extremely undervolted profiles but, at standard voltage, was stable at 1150 MHz...
So, just try though imho undervolting and scaling to save battery life are more appealing than oc itself.
---------- Post added at 01:18 AM ---------- Previous post was at 01:08 AM ----------
One more thing, because I had missed a part of your post.
IMHO overclocking and overvolting together are the evil itself because of the heat that such thing would cause and the phone is not a pc with its fan to refresh...
Much better oc and undervolting
I'm using the just released LATAM OTA leak (but this also holds true for the first LATAM OTA leak).
The default governor for this 2 OTA leaks is 'interactive' but I was having a very choppy gaming experience, then I decided to change governors and analyze what happened.
When I give 'hotplug' a shot I noticed a much more fluid gaming experience and as time passed I also noticed my battery life was much better.
Did anyone else notice this too?
Anyone else willing to give it a go and share what do you think?
hotplug works better for me as well. ICS LATAM
I hope it gives better battery, it shuts CPU 2 off/on when its not/is needed.
hotplug is the same as ondemand governor except with the ability to turn off the second core when not in use.
How do I change it
Sent from my .211 leak razr do you wanna get cut?
get setcpu or any other cpu management app and then change the governor from in there.
This is great thanks for this thread, i was just thinking of posting this answer in question form.
I notice interactive is not a good as hotplug
Sent from my XT910 using XDA
You can google up SetCPU governors and there are detailed explanations into how each governor performs and their advantages/disadvantages. For most stock kernels, hotplug is the way to go for dual core phones as most of the better ones are usually in custom kernels.
Will hotplug save more battery than conservative?
I guess you must be rooted for that ?

Yes, of-course. Really works for me too, noticed greater performance and battery life.
unfortunately, not for me. i use CPU Tuner to change from ondemand to hotplug, and the performance was a little more laggy.... dont know about battery life though.
question: whats the high/low threshold you guys use? by default, setting hotplug in CPUTuner sets it to 60/40. i know something like 90/98 probably saves a LOT of battery, but performance is crap. and i dont have time to do full trial n error.... lol

no but seriously how much do you guys think we can turn this thing up (overclock) and it be stable? (like its really needed..i cant get it to lag now as it is) once we get a kernel that is

1800 is a VERY good starting point.... I ran a kernel when I had the International variant and it was FAST!! I think it was called "Bullet" kernel...?

I was looking stuff up on that today. The highest I could find documented was 1900 on the cpu and 800 on the gpu.
For everyday usage, overclocking is useless, even for gaming. Undervolting can be beneficial, but from what I've seen, the latest processors get approximately the same battery life on stock voltage as they do undervolted.

hey thats good to know...like i stated though. if there ever was a phone that needed over clock this one IS NOT it. i cant bog it down right now and believe me ive tried. someone out there might can but i cant.

I just like to play around with different kernels but the kernel I was using def made the device snappier and I had some killer benchmarks! But you are right though! Custom kernels on this device is not really necessary...
I plan on building a custom kernel then, hopefully tomorrow night or possibly Saturday. I do have some plans to improve it, but nothing related to the CPU or GPU going faster, just having other stuff operate better and getting rid of anything not needed.

I hope I don't get another lemon CPU... my TBolt's would only overclock to 1.4G, anything above and it locked up.

That's better than me. I could run 1200 for weeks but at 1400 about every other day it would restart randomly.

HA. My TBolt stayed stable at 1200, but ANYTHING higher than that and it would crap out on me.
I could run my bolt stable at 1700 all day. Kept it at 14 for a month no issues. Stayed at 13 the rest of the time. Course at 17 it was like it was running on a watch battery with the amount of time it would last. Lol
Eh I ran 1.6Ghz on my Thunderbolt 24/7 and with the 2750mah battery it lasted me days.
On a phone like that there was a significant improvement to the end user that justified the overclock. Now on the Note 2 I'd expect there to be very few who would want an overclock at all. I am part of the very few however. I play a lot of emulators on my phone and for N64 and Playstation I need all the raw CPU power I can get. Yep, even on this beast of a phone I still get some lag and stuttering on those emulators. The reason being is the same as PC gaming. AMD thinks that by adding more and more cores to their processors they can win the performance arena. Unfortunately they are wrong. Intel has the right idea, 4 cores is plenty now let's improve the efficiency and performance of those specific cores.
Same goes for our phones. Quad core is the most I'd ever want in my computers, anymore is just a waste. Now let's get better architecture for the processor to maximize clock-for-clock performance. And overclocking those cores helps it in apps that don't support more than one or two cores, because the baseline performance for each core is boosted.
So yeah, can't wait for a 1.8Ghz kernel
These settings have been tested by me all night and all day checking the timesnin each clock state and if it failed it would be a simple fix . This is as stable as can be lowering your temps and increasing batterylife!! No more screen dimming. I stopped the undervolting process at 1728mhz because at 2265mhz regardless the phone would overheat
So here are the specs below
300mhz----750mv
422mhz----750mv
652mhz----750mv
729mhz----750mv these are as low as I could go
883mhz----760mv
960mhz----770mv
1036mhz---780mv
1190mhz---790mv
1267mhz---800mv
1497mhz---810mv
1574mhz---820mv
1728mhz---830mv
These settings are to be inputted directly into setcpu via voltage table proven to work
These settings are also tested daily and improved where flawwed
I figured i would post this since there isnt a single post with manual voltage specs
Good info thanks!
You got it!!
Have any voltages setting for OC?
Are these settings good for gaming?
As posted these voltages are strictly for batterylife however does just fine on gaming. I will work on oc voltages once the cpu limiter is removed from any kernel unfortunate it would be pointless to overclock this handset
Why can't I adjust voltage settings on a stock kernel? I don't get an option to do it in the fauxclock app...

you do know we already have 2 over clocked kernels for tw. so its not exactly pointless.
These settings are for people who want batterylife and to enjoy theyre phone without the screen dimming on them from the cpu overheating on them.. i dont see a point in overclocking the phone. Maybe some quadrants and horrible batterylife
There are some that want the most battery in a device. Others want the most performance. I and others are in the 2nd category. I personally have a zerolemon so battery life is a last priority for me seeing that underclocking this handset is pointless to me. But to each their own. I do aprreciate you taking the time to find out these voltages but to some OC is just as addictive as flashing roms themselves lol!
Thats fine you can enjoy your screen dimming 2.7ghz while i have the zero lemon and underclocked at 1728mhz and undervolted lasting 6 or more days and still screaming fast. Sure there isnt a point to it huh

MY NOTE 3 BETTA THAN YOURZ
does any one have the stock kernal voltage to maybe compare
i tried these settings
set up fine
300mhz----750mv
422mhz----750mv
652mhz----750mv
729mhz----750mv
883mhz----760mv
960mhz----770mv
having issues on this half
1036mhz---780mv had to set to 800 because it kept freezing blacking out
1190mhz---790mv 820
1267mhz---800mv 850
1497mhz---810mv 885
1574mhz---820mv 900
1728mhz---830mv 915
Stock Kernel Nope.
This WILL not work on a stock TW kernel as SETCPU or Voltage control do not have the ability. The only way to change voltages (unlike the title claims) is to flash a NON stock kernel first.

This is due to variation in chips, when the processors are manufactured they are tested, separated by performance, and priced accordingly (this is called 'product binning'). Those of you using OP's settings with no issues have similar or better processors, and likely could undervolt further.

yes true and i understand
my only reason for saying that is he has a note 2 in his signature plus we have a 2.3ghz processor soo y would it overheat?
plus our cores are handled bit different because we have a snapdragon and well the note 2 has a exynos processor :fingers-crossed:

The clock speed, voltage, and heat are all directly connected; changing any value will affect at least one of the others.

These theories are equally applicable to all processor types. The issue with these one-size-fits-all settings is we are using cpu's from multiple different bins, thus they can tolerate different voltages/clock speeds. It's also worth mentioning that 2 cpu's from the same bin will tolerate different settings (as they came from different wafers) and that even 2 cpu's from the same wafer will likely tolerate different settings (depending on it's location within the wafer).
In other news, I've found THIS extremely useful thread that explains how to go about revealing your bin # (Thanks @toastido for noting that KitKat changed location to /sys/devices/system/soc/soc0/soc_pvs :highfive. The thread also has multiple users end settings and benchmark results.
Last but not least, to finally answer your original question: I found in that thread that your original settings will vary depending on your bin # (There are no universal stock settings) but perhaps you can find someone who posted their original settings from the same bin that you have. Hope it helps, cheers :good:
