[Q] Overclock GPU? [ i know sounds crazy ]

Same devices like HTC HD2 with Snapdragon, when you overclock the CPU, the same happens with GPU...
But in our case ( defy ) is not the same...
By default ( where i know ) PowerVR SGX530 it's runing AT 200Mhz, but can run higher, than 200mhz ( 400mhz i think ).
We can overclock the GPU to get more 3D performance, witouth sacrificate the battery?

Why do you think the GPU can run at twice the default clock speed?
If there is an article you have read that states or suggests this - please provide a link.

by default it's runing at 110Mhz ( i think )
http://en.wikipedia.org/wiki/PowerVR
the default clock is 200Mhz, and i thing can go furher.

I have seen traces of 125mhz looking in the system files, but thats more of a guess

according to ti, it is [email protected] (all 3630 is)
well it's either CORE_CLK/6 (0x1) or "full speed" (0x0) (CONTROL_FEATURE_OMAP_STATUS)

Ok, but is there any way to overclock the GPU? at 250 or 300mhz maybe?

This program on the market says it can overclock GPU:
Overclocking (GPU / CPU) https://market.android.com/details?id=com.cpufree
but doesn't seem worth trying since it has a very very bad rating and comments.
Last app update was 5 months ago.
Can someone find an app worth trying?

Would be cool if the gpu ups with CPU, but like mentioned above...I think the omap3630 is locked at 200mhz
If anyone knows how to do a gpu OC...please share

dunno about you guys, but as far as i know, the gpu is integrated in the cpu chip (its like an extra core so to say), so it should be overclocked with the cpu. and whenever i ocd the cpu, i experienced graphics improvements, so i think, thats the answer, they oc together.

No they do not OC together i am afraid. Most of Android UI is being drawn by CPU and not by GPU as many thinks :/

Well, I've experienced minor changes when OCing my Defy from 1ghz to 1.3ghz, when using Neocore... it went from 39fps to 39.3 fps, but such small changes are expected, even without OC...

Overclocking the Mali GPU

So guys,waiting for my GS2 to arrive tomorrow and it's time for the hundred bucks question:
Will we be able to overclock the Mali GPU in the GS2 like the SGX540 in the original GS was?Imagine the performance of this thing with an overclocked GPU!
And before you ask,no,its stock power isn't enough for me.As long as I can get more out of it that is.I will probably have it running at 1.5GHz everyday,so I'm not the kind of guy who will "proceed with caution"!
Thanks!All feedback welcome!

I've got my CPU underclocked to 500 MHz and honestly can't tell the difference between 1.2 GHz and 500 MHz...
I even gave my phone to a colleague who has one too, and he was using it without a thought. He indeed asked me why mine was faster than his... xD
So not a clue if you can OC the GPU, but I've yet to see a single reason to OC this phone.

Well,power corrupts my friend!And with a phone so powerful I can't help it!
Seriously though,it is nice if something like this is possible.See the original GS.The overclock of its GPU puts it against most dual core phones easily and it even bests some of them.Not likely something everyone will need in their everyday lives but you never know what the future holds!Maybe we will rival the Kal-El(Not likely I think but let's hope)!
Happy to see you here by the way pulser.It's really an honour!

I have almost the same experience here, except I could see a difference between 500 and 800 Mhz, but anything above 800Mhz almost didn't change anything. Which proves that the CPU is not the bottleneck, so we should try to overclock the GPU

ALMOST in my mind.Almost.My CPU for one will be a 1.5GHz one!Or even more!
Well,since pulser gave attention to the thread I am a little confident it might even be followed by some devs at some time(or that someone works on it at least),so I want to ask these two regarding the lack of texture compression formats issue:
1)Does anyone know whether Chainfire intends to make any plugins for Chainfire3D himself?While the available plugins do the job for some games,they don't for some others.So,I think Chainfire is our guy on this!
2)Is the issue hardware or software related?If it is software,what are the odds that Samsung or ARM provide a driver with support for all texture compression formats?I don't think that's likely to happen but,oh well,we can always hope for it!

It's definitely hardware related. Mali doesn't support Nvidia's, PowerVR's or Adreno's proprietary texture compression formats.

I think the gpu get overclocked with the cpu or at least that's how it was on the s1.

I think it was seperately overclocked with a special kernel on the GS...I could be wrong but I doubt this as it had made me feel very jealous that it wasn't possible with my Desire.

no, CF3D is a work around this VERY hardware "issue"
there can be other hardware things that aren't compatible however.

wait isn't the Mail 400 GPU a quad-core? I've been hearing that it is but Samsung have disabled 2 cores to a dual core GPU.

I think with dual-core they are referring to the CPU only.The GPU must have remained quad-core.Else how would it pit against the octa-core GeForce of the Tegra?

omg i got 5000 (4951) score in quadrant overclock 1.6 ghz 1400 mv

With tegrak kernel and tegrak OC utility you can OC GPU, normally it idles at 160MHz and under load clocks to 267 MHz, max OC is 400MHz but phone gets really hot.

mine is stock. when the i play f&f 5 the battery would reach 10% in 2 hours!! so my guess is that oc the GPU would cause a huge drain for the battery

does the kernel offer good alround support?

It's stable and provides great performance. Although I'm using Ninphetamine right now. Can't use Tegrak oc with nin though. Only setcpu. Nin is oc to1.6 ghz. Tegrak is oc to 1.45GHZ.
EDIT: Just switched back to Tegrak kernel. Manual oc to 2.0 GHZ..Using Tegrak Oc. Stable.

Adreno 200 GPU Overclock

Hi, I have a question!
I'm absolutely happy with my HD2 but I'd like something that the performance increases.
Is there a possibility to overclock the GPU? Cpu is yes to either 1.2 GHz or 1.5 GHz but the power play in is not very noticeable so I would appreciate if you could overclock the gpu order to get more performance out there.!
know her as a possibility?
would answer me happy!

there is an app on the market that allows for GPU overclocking , i didnt use it personally just search overclock in the market and look at the different results . I have no problem with the performance of CPU overclocking , i always thought the CPU was the one in charge of graphics rendering .

Isn't it SOC? As you overclock cpu gpu is overclocked also?

Good point . But couldn't that lead to more problems ? Too high of gpu could cause failure in stability but the CPU can handle the high oc ?

yea i really wouldnt recommend touching that, as far i remember we are already running diff os's that stretch are gpu and cpu with hacks and kernels etc....

is there any kernel that supports it?

Why would you want to overclock it, mate? Is 450 Mhz not speedy enough for you?

to see how it would perform against 550 and 578 clocked 330s.

CM 12.1/13 Kernel that supports GPU overclock

is there a cm 12.1/13 kernel that would let me overclock the GPU and RAM bus as well and not just the CPU ? been skimming through the forum to no avail, currently on teamsek cm 13, it's great but i can't overclock the GPU and bus using it's supplied kernel, i'm even willing to downgrade to cm 12.1 if such a kernel exists for cm 12.1

how about the gpu ?

You can try to oc gpu using synapse or similar apps but people say there won't be any difference by oc'ing gpu.

but then the kernel has to support gpu oc, other wise synapse won't work, i would just like to push the frequencies on the gpu to snap dragon 801 level

no more inputs ?

Maan, you are still trying to OC the GPU?? I answered you 2 times already. IT IS OF NO USE! GPU OC will even slow things down due to heating up like hell! RAM connection is the bottleneck in our case, so it won't help at all, except your goal is the kill the phone to buy a new one very quickly...
