[Q] How I can overclock my GPU?

Hello everyone!
I will overclock my GPU. Somebody know how I can do this?
I have:
Xperia R800i
unlocked bootloader
root

Not very sure about what I'm about to say...
As far as I know you can't, the CPU and the GPU are on the same chip, so if you OC your CPU you're also OC'ing your GPU, BUT, there's also an app I haven't tried yet, I just read about it somewhere in this forums, if I'm not wrong its name is Voltage Control, it lets you tweak a lot of things about your CPU, GPU (what I read), voltages, schedulers, etc, just... be VERY careful.
Hope I was of help

Oh yeah I was forgetting something, you need to flash an alternative kernel to be able to overclock, by just having root access you will only able to underclock.
I recommend you the DooMLoRD's DooMKernel, look for it on the Development forum of the Xperia Play

jhonyrod,
I'm already have doomkernel v10 and OC CPU. (1.6GHz)
Thank you for information.

I'm about to install that app a was talking about, if you give me some time to look around I'll give you more info.
EDIT:
Ok, I installed the app, as far as I can see it has many other options but only for supported devices (the screenshots are actually showing a GPU tab), sadly, our R800 are not, it can only change the cpu governor, the I/O scheduler and the freqs... Maybe I was right since the beginning; CPU/GPU are on the same die, and when you OC your CPU you are OCing your GPU too, even though you can't see it, but in my experience (and benchmarking) it does.

[Q] Xperia Arc CM 10 OC

Hi,
I got CM 10 FXP 137 installed on my Arc LT15i and everythings working well so I wanted to test overclocking capabilities.
In Settings>Performance>Processor I pushed the max CPU frequency up to 1.6 GHz but I am afraid of causing a damage.
Now my question is if someone knows how this frequency selection works.
Do I only change the frequency or is CPU Vcore auto-adjusted with it and if it is the case please explain me how I can manually adjust the both of them seperately.
I hope you can help me and understand my text (sorry for my english).

The frequency, that it is working on CURRENTLY, depends on the CPU governor, that you have chosen.
http://forum.xda-developers.com/showthread.php?t=1369817 - This thread has info about some governors.

post it In Q/A

Thank you for your help.
I will search the thread and if there should be a question remaining i will post it in Q/A.

[Q] Undervolt, setCPU, and DoomKernel v14

Hi guys. I'm using DoomKernel v14, so far so good.
I install setCPU and set a couple of profiles, but when I went to undervolt there was no undervolt tab on set CPU. To handle this, I install SetXperia but when I activate setCPU profiles on boot my Xperia PLAY crashed and reboot soon after boot. So, I guess I should NOT use setCPU and SetXperia at same time, problem is I need to undervolt my PLAY so I can squeeze more power from battery.
I read the documentation (well, sort of...) in SetCPU webpage and it states "The Voltages tab is only available with some custom kernels and devices. If the Voltages tab is available, it will automatically show up between the Governor and Profiles tabs. Otherwise, the Voltages tab is unavailable.".
Now my question is: Why SetCPU is not allowing me undervolt when is obvious that DoomKernel v14 allows this (SetXperia allow me to undervolt after all)?, more important, how do I fix it?, if I change to Lupus kernel will I be able to undervolt with SetCPU (will the undervolt tab be enable in SetCPU)?
Thanks.

Ok, I just install Lupus kernel and still there is no undervolt options in SetCPU.
I'm open to suggestions.

SetXperia can modify your voltages: https://play.google.com/store/apps/details?id=com.SetXperia.Inteks.org
It works with both Doomkernel and Lupus.

Yeah, problem is, with SetXperia I can't set dynamic profiles like in SetCPU...

[Q] CPU/max frequancy Nozomi Rc02

Hello,
I am really sorry, my English is very poor, so my girlfriend and google translator help me translate... I am a beginner on this site.
So I have ROM RC02, but I can`t change max procesor and CPU governor either... Whenever I press changing CPU and max, it brings me back in original position. Could you please help me?

Try setcpu app
Sent from my Jellybean Xperia S

Ok, I'm in SetCPU or Voltage Control in the changes there and I will remain so, but the phone settings in Perfomance I still have the same values​​. So now I do not know that are set ... :/

maybe u can try kernel tuner app.
https://play.google.com/store/apps/details?id=rs.pedjaapps.KernelTuner&feature=search_result
it can control both of the cpu0 and cpu1.
cpu0 work ok and value doesn't change after i set.
but for cpu1 sometime it back to 1134mhz when i set to max value. but i just ignore it as it most of the time set at max value. seem like it can automatically adjust itself.
and i suggest PerfMon app to monitor your cpu. useful app for me.:good:

[q] cm 10.1 uv

Can I under volt on cm10.1 ?
I have installed greenify but to be honest there us not much to freeze
IM+ watsapp and tapatalk and teewtcaster pro those are my most " demanding" apps
If I use any of them the battery life goes down at a rate of 1% per 2-3 minutes
The screen is close to the minimum
Also how do you change the IO scheduler mine is on cfq but regardless of what I press does not change any suggestions ?
Thanks in advance

I use an Arc S but I underclock it to 1GHz. The ROM does not lag.
Did you check the box that allows you to keep the settings at boot?
僕のLT18iから送られてきた

Hello
I have an arc S lti 18
That us the issue i cannit change it so if I press sio for example gets back to cfq so no way to set it on boot because it reverts back
As for undervolt I had a uv file that i used on lupus ICS which helped m to keep the phone runnkng with very low use of battery But not sure if will work on this i can pm you the file if you want to review it

There are plenty of apps, which can do the undervolting, look in Play Store. SetCPU, SetXperia + many others.
According to the kernel status for LegacyXperia CM10.1, then the undervolting should be possible.

Thank you
Any in particular you would recommend ?
