I'm guessing no since tegra drivers are close-sourced. But I could be wrong.
The GPU is indeed Overclock able, and the epeen version of vorkKernel for CyanogenMod Overclocks the GPU a little
Thank you.. do you know how much? btw brothers in arms 2 is lagging like hell..

The GPU is overclocked from 355Mhz to 366Mhz, on the EPEEN version of vorkKernel. But remember only to flash it if you're running CyanogenMod
Wiki says original is 300mhz for 2x or am i missing something? Btw strange thing ive noticed when running multitouch benchmark try to add more than two fingers and whatch fps drops from 120 fps to 60.. is that normal or there is touch bug like there was in optimus p500.

300Mhz might be the default. In that case we have some OC on the default one too.
Lag might occur on touch depending on ROM and stuff. One some devices a lot of log spam happens, and this slows down the device considerably
Ok thank you, same drops on cm7 fresh install as on fresh stock v10b its like 10 fps for each finger..

It's kernel doesn't support OC, you should flash an alternative kernel like swiftkernel, see thread in dev section.
And you're off topic, his thread if about gpu overclock, not CPU.

oopsy sorry
so whats the difference :O
the tegra also can be overclocked??

GPU is the graphics chip.
CPU is the chip used for everything else.
Overclocking the CPU will see performance gains in nearly every field, and the Tegra 2 can be overclocked from 1GHZ to 1.55GHZ or so.

oh thanks , but what is it that we usually overclock??
is it the cpu or the gpu??
seen o2x with 1.5ghz
so is it the cpu that is oc or the gpu??

just a quick through :
cpu can be overclocked(controlled by pimp my cpu/setcpu)
gpu based on source code can be overclocked too, but i can't find any voltage control that control gpu clock. so, overclock gpu is really minimal, from usual 335mhz to 366mhz. in benchmark, you won't see any noticeable score. so, i don't know if the gpu overclocking working fine or not, 30mhz increase seems not helping...
cheers...
Is there any way to reach 400mhz?
Sent from my Optimus 2X using xda premium
Yes it comes.. but based on my testing,it will cause black screen of death after screen turn off for several minutes. Normal clock or a little increase doesn't make those problem.

Try to set cpu min to 800mhz.

Hello!
Since there are some kernels that support GPU overclocking:
1. What GPU clock do you use?
2. Is your GPU undervolted?
3. Do you see any performance boost with overclock? (eg. benchmark or gaming)
4. Is your battery life the same as before? (or better/worse)
Another thing, does anyone know if you overclock our Nexus 7 GPU - does it stay there or it has no effect?
Have fun!
My example:
1. I OCed my GPU to 520mhz
2. mV values at 520mhz is 1175
3. My benchmarks are the same - I think I can see some performance improvement while gaming (might be placebo)
4. Can't really tell
i overclocked my gpu to 500mhz
with an undervolt of -50mv
You should also list what kernel you are using

Running M-kernel a40 with GPU at 500 no under volt, I see slight improvement in graphics benchmarks but you won't get much because of the RAM bottleneck. My battery is only worse if I do a lot of gaming

Don't use 500. Use 446, 484, 520, 600, 666, or 700. Complicated reason but trust me.

Ha thank you sir, I almost forgot about the "proper" values. I know the basics of why it needs to be those values
Sent from my Nexus 7 using xda app-developers app
600mhz, 1300mv, testing and searching for the lowes and more stable voltage for this frecuency.
Oh, and Metallice, why we need to use 600, 666. 700 or the other values? And, how much voltage the cpu and gpu on this device can handle?
Edit: 520 mhz using faux kernel ultimate, I don't know the voltage on his kernel.
is it possible that i enable only one core and disable all other cores of my cpu ? How???
I'm on CM 10.1 RC1 On v20a official - rooted - unlocked - with CWM recovery
You can do that by using an app called Tegra Overclock for example.

it doesn't have optimus 4x in the supported list
Our phone is supported, don't worry. We got Tegra 3 processor. I am using it daily to improve performance (mainly in games to overclock GPU and to REALLY force all 4 cores to work).
Here's a couple of screenshots that I just made to show you.

Hi guys, what app for tweaking do you use? I don't know wich one to use. I need an app for setting gpu clock, cpu clock, voltage and active cores.
Thank you!
Trickster mod is probably the best :thumbup:

It's good app too but it was a bit buggy for me before so I switched to TM but it may work perfectly for you

What bug have you found in it? And with wich app i can set to use only 1/2/3/4 cores??
I'm using Tegra Overclock, Pimp My Rom, System Tuner Pro and Trickster Mod.
LoKKeR, I'd highly recommend Tegra Overclock for settings number of CPUs.

I'm trying to use Tegra Overclock a lot since it sounds really useful but when I install it I CAN'T DO ANYTHING! Seriously, I touch the icons and nothing happens, the only thing that happens is that the cpu freq on top is allways updating, but the app itself doesn't let me do anything ! Any thoughts about it ?

This could be the possible reason! Either that or wrong kernel..
i have compiled a nexus 7 kernel similar to this http://forum.xda-developers.com/showthread.php?t=1903304 but for 4.3 roms the main theory for this kernel is less heat and more battery (i was able to get 7 1/2 Hours SOT With 2 Days Standbye)
These Are The Features
1.vdd_core/vdd_rail ,emc, pll_c, host1x, GPU, CPU Pre Undervolted
2. CPU LP Overclocked To 666MHz
3. Speed of GPU 2d/3d/vde etc set at 400 mhz (close to stock of 416) (Also 228MHz GPU Step Decreased To 215MHz)
4. 1300MHz Quad Core Patch
5. Min Backlight Level 5
6. host1x Underclocked From 260MHz To 255MHz
7. Some MISC. Tweaks
8. FSYNC TOGGLE
Tell Me What Your feedback Before i make a thread in development section
it has Mkernel Ramdisk So it should boot on all roms ive only tested cm10.2 though (i will not be adding voltage control as i think this kernel has a good undervolt 75-100mv undervolt on all frequencies)
Enjoy

Okay no worries, just wanted to see in detail what you did exactly Cheers mate
Nice kernel for start! Always favor battery save kernels.
Keep coding and create thread in right forum. I'm sure many will be interested.
Good luck!

Has anybody actually tried kernel or am I being questioned close-minded here ?
What is the steps for the instalation?

Not sure why you think we're being closed minded? Some people post on here claiming battery life of 11+ hours, so 7 might not be that good, alternatively you might've just increased from 7 initially to 7.5 now. Wouldn't be worth my time, given the problems I've had flashing kernels before, if the increase was hardly noticeable.
Doesn't hurt to look into stuff a bit more before we flash something completely new with little info.

Yeah but there's nothing as remote testing for a kernel. You have to try and see for yourself. All info lies in OP's post, anyway.
