Hello everybody. Just wondering if my Cpu downvolt has became in a performance improvement, especially in games. After downvolting cpu (gpu was already overvolted for overclocking to 400 mhz) I noticed an incredible improvement on games like nova 3 and asphalt 7.
Could you tell my what are the stock cpu voltages for... 200mhz, 400mhz, 600mhz, 1000 mhz and 1200 mhz clocks?
Thanks

200mhz = 950mV
400mhz = 975mV
600mhz = 1000mV
1000 mhz = 1175mV
1200 mhz = 1275mV
Undervolting cpu means less performance? I Undervolted with a option from my kernel. Seems to get same quadrant score. Shoild i do other tests? Is it ok? I Undervolted just 25mv. I want good performance and good battery. Already removed a bunch of após with alot of wake up and wavelock. It Seems its much better

Undervolting results are fairly different because it depends on the usage.. if your.phone get lags or random shut downs or random reboots, then your phone cannot handle the UV.. but as what you have described, your phone seems fine

Undervolting doesn't effect performance, underclocking does.
However as already pointed out if you undervolt too much your phone can freeze or reboot.
25mv undervolting is fine

Tested with - 50mv seems not to have problem done a bunch of stress tests. Seems Nice

Gone back to - 25 loool spoke to soon got 2 freezes

Undervolting can be hit and miss. You just have to spend time tweaking and testing and find the best values for each frequency
I use an app called voltage control it's a great tool.

I have been uv many times on different kernels. Still can't say if that really save more juice. You know, in theory it does. But there are plenty of other things that do. Starting from less brightness and being carefull what apps you install... I recommend GSam Battery Monitor to watch them.
How about gpu? Is bad to undervolt? Thanks again

Ehhh. Don't Undervolt GPU. You will get constant freezes especially when you are playing games.
However Undervolting CPU by 25-50mv is fine.
Kernel configuration was:
200 Mhz - 950mV
300 Mhz - 975mV
400 Mhz - 975mV
500 Mhz - 975mV
600 Mhz - 1000mV
700 Mhz - 1025mV
800 Mhz - 1075mV
900 Mhz - 1125mV
1000 Mhz - 1200mV
1100 Mhz - 1250mV
1200 Mhz - 1300mV
Made a Manual configuration:
200 Mhz - 875mV
300 Mhz - 900mV
400 Mhz - 925mV
500 Mhz - 925mV
600 Mhz - 950mV
700 Mhz - 975mV
800 Mhz - 1025mV
900 Mhz - 1075mV
1000 Mhz - 1175mV
1100 Mhz - 1200mV
1200 Mhz - 1250mV
Seemed to be stable this way. On 1000 Mhz i couldnt undervolt -50 for some reason, gave imediate freeze. I've made 30 secound stress test on each frequency. Seems to be working fine

Good post, very best working on 5.1.1 dity unicorns
So, I managed to undervolt my s3 to the point that I'm scared to do it further (freqs 1600-900 are final, 800MHz-200 still open). This settings are fully stable (2 days no reboots...yet). I was desperate to lower my batt temperature due to thermal throttling in order to play some heavy game on emulator, and well - didn't expect such results!
1600MHz - 1212.5mV (-137.5mV)
1500Mhz - 1150 (-137.5)
1400MHz - 1075 (-175)
1300MHz - 1037.5 (-162.5)
1200MHz - 987.5 (-150)
1100MHz - 937.5 (-162.5)
1000MHz - 912.5 (-125)
900MHz - 862.5 (-137.5)
800MHz - 775 (-187.5)
700MHz - 750 (-200)
600MHz - 737.5 (-200)
500MHz - 712.5 (-200)
400MHz - 700 (-200)
300MHz - 700 (-200)
200MHz - 675 (-212.5)
ASV Level 8
Guys, if you managed to go achieve similar results post it along with your chips' ASV level, the other threads seem dead
My Sony XZU GPU is running at 450 MHz stock, and Doomlord showed us how to overclock to 533 MHz.
I am seeing devices in 3DMark with Adreno 330 running at 578 MHz, like the Z3, Z2 etc.
Is there any difference on the chip?
Due to overheating issues I've underclocked z5c cpu ( using this method and flashing the recompiled kernel ), is it possible to do the same with gpu? Which file do I have to look for?
AFAIK Adreno 430 runs up to 650 Mhz, 450-510 Mhz should be enough for my standard usage.

I have no idea but you could take a look at the Adreno idler commits...
Here is one I did to add 27Mhz as the lowest clock (might be a good file to look at), instead of 180Mhz...
