Hello,
Just wondering if anyone has experimented with Tegrak Overclock Ultimate's GPU optimization settings. It allows you to undervolt the GPU. Has anyone tried this and is there any benefit to battery life savings with this? I am playing around with the settings right now, so I'll post my results later. So far been able to undervolt the 267 mhz step by -75mv from 1000mv down to 925mv (900mv is unstable for me). And I undervolted the 160 mhz step by -150mv from 900mv down to 750mv. There is also a 200 mhz step I haven't played with. Perhaps keeping the GPU at 200/160 can yield potential battery savings when playing games because games drain the battery so fast.
Hm. I seem to be able to undervolt the 200 mhz step to 750mv as well. I'm going to run a 200/160 gpu setup at 750mv and see if I can save any battery playing Gun Bros and will let you guys know.

Really? I only have the 267 and 160 MHz clock settings available. Any thoughts anyone?
Oh, I have underclocked my GPU settings but only by a modest 25mV each.
There's only 2 steps, but u can change the clock between 160, 200, and 267
yep ... good results
Yep I've been experimenting with GPU undervolting and had some sucess. So I was methodically working downwards and testing stability... then i saw this thread and thought what the hell, right? I shot for lowest mv of 750 and it's rock solid at 200mhz.
Can confirm 750mv stable at 100, 134, 160 and 200mhz. 267mhz can't be undervolted that much.
I've locked 200mhz 750mz for both speed steps and left it at that. Phone has yet to display any instability in a couple of days of mixed use including gaming. Battery life better? Subjectively yes, mostly I notice phone doesn't get so hot playing Dead Space.
Power consumption scales down almost linearly with clock cycles, and exponentially with voltage (right?). So by my math GPU is using about 40% of the power it does at full 267mhz. I wonder what the TDP of the exynos 4210 is and how much the Mali 400 contributes to that, would give some idea of what battery life to expect. Since GPU sits idle a lot, I doubt it's a magic fix.
Such is the power of our phones I have to underclock the CPU and GPU quite far before any 3D game gets too choppy to play. 160mhz is more than fine for most.
Usually undervolting makes the most sense for power saving because a given computing workload takes a certain number of cpu cycles. But 3D usually tries to render as many frames as it can, with the exception of S2's 60fps frame cap. So slowing down the GPU to no more than you need might improve gaming battery life?
My SGS2 is a bit sensitive to undervolting although underclocking of CPU, so I'm happy be able to so agressively undervolt the GPU.
I'd be interested to know who else can just set 200mhz & 750mv and have it rock solid? If not, 200/800 or 160/750?
I've rarely had problems when I use Tegrak. Then again, I undervolt 100mv on my cpu between 200-1000mhz, and about 50mv on my GPU at 267mhz with the noop scheduler and tweaks enabled. If I can get Tegrak to work with the Gunslinger kernel (currently causes reboot loops when I load the overclock module), I'll report back on battery life with Tegrak and experiment a little more.

I had the same problem with Gunslinger, I decided to keep my phone on Rogue Stock EL29.
I've been able to drop my GPU Level 0 Clock to 160mhz and voltage to 850mv with out any issues.
I also keep my GPU 1 Clock at 100mhz and my voltage at 750mv without a problem.
Using noop of course.
Changing GPU clocks and volts doesn't help much.
Keeping your CPU Internal Voltage and Core Voltage -50mV and keeping it scaled 200-800 MHz will give you much better battery.
I think the effect would be more significant in ICS since ICS use GPU to render UI
I think GPU drain battery very much when play games
How to under voltage GPU and how to test stable it ?
In rom control > cpu frequency?
What value have i set on min and max?
What type i have to set on governor?
What type i have to set on IO scheduler?
All setting cpu freq depend on what?
[ROM][AOKP][JB][RC]ARC S[Build 5]
[KERNEL][FUSION v3.7]
Have min and max set as the highest or 1.4 . set governor as performance, and have 'noop' as IO. Of course, the frequency entirely depends on what you want from your phone - best performance with high battery drain, laggy as hell performance with best battery life, or somwhere in the middle

the higher the frequency/value, the faster and better performance your phone will have. So depending on how slow/fast you want your phone, set the frequency/value to the appropriate/corresponding level of performance
Basicly you have to experiment with the cpu freq in order to determine the best freq for your desire (gaming,smoothines,battery drain)
As for guvernors - Performance will always keep it at max freq so it drains ur batttery like hell
- Smartass will use lower freq and less the max freq so its the best for battery life and smoothines in my experience.
If you used search you would have found -> gouvernors info
Gouvernor Infos
AS for I/o sched -Noop has the best ratio for perfo/batt life.
Performance sheeet comparison of sched and guvernors

Better set Interactive because performence eats battery
cpu
what the best cpu ferequency for arc s?
for bettey battery life?
what is governor?
what is i/o schedual?
ihave a problen in set cpu
i set the cpu for an app , and when i go to app and after close the app , don't back ferequency to values that i set in the main screen
and the ferequency set to maximum

A THANKS is appreciated

Thanks,

Performance governor will never let your frequency go lower than 832mhz so setting a min frequency is useless
Powersave will never let it go higher than 156mhz so read above
Bcm21553 will only use 312mhz and 832mhz...
Sio is slightly better than Noop

1562? or just typo?
Also like technosavie, I use lionheart. Try it :good:

I have updated it... Sorry for the 1562Mhz... 156Mhz it is Srry! And I updated it just now... PERFORMANCE replaced with LIONHEART!

Maybe some examples regarding the USAGE like Texting, Music or Data mode something like that i think

Updating
Using stock rom with hell_fusion kernel. Freq at 624-312mhz, ondemand+sio gives me at least a day and a half.
Wifi turned on, playing games once in a while, music for a bit too often, and a lot of facebook.

These settings were for Savie #1, #54 and percy #1 hell fusion #50

[Q]
What is the recommended kernel? Is hell's fusion #50 good for all needs, or kuro's kernel better?
Also is Merruk Kernel v2.0 (1.248GHz) stable to be used for everyday apps?

I used Merruk but it occurs a fex probs sometimes... For some needs you need to have stock recovery not cwm soSaviekernel or Kuro is highly recommended

Kuro's kernel is definitely a keeper! Its very light.

Yeah!
Bcm + cfq is good.
Bcm + noop is slightly smoother, but eats battery.
Well, for battery, you can't go wrong with powersave and sio.
As for me, though, i use scary+deadline. Seemed pretty balanced for me.

I dont know
Interesting. Thanks.
Can i adjust my min frequency with tasker?
Can't find option with latest dirtyV kernel.
I would like to set it higher because i have extended battery and my battery life is great, so i would like to improve smoothnes.
