Hi everyone
It might be a noob question but.. everybody concentrates on CPU overclocking. I wonder if we could overclock the GPU in order to make games run smoother ^^
Thanks

Moved to Q&A as not development.
The hero doesn't have a dedicated graphics chip, AFAIK. So the CPU is used to render everything. That's why Live wallpapers cause lags on 3D ones, or just don't work.
HTC didn't see a need to put a dedicated GPU on the Hero CPU overclocking is all we can really do, other than optimising dalvik etc.
Oh.. i see, thanks for the reply.
But, it means that maybe the DROID could have a GPU Overclock ? Or the other device having a GPU but, i only see people oc their CPU. Maybe it's smooth enough so they don't need to oc it xD ..
Damn HTC ..

Is there a way to overclock the Adreno 220 GPU that I consider to be laying dormant as of now inside the HTC EVO 3D and Sensation? I read some of post the the Desire HD section that mentioned they were jealous that the sensation already got a GPU overclock but they didn't provide a link and my searches have come up with nothing. If I could, I would post a link, but I didn't find anything. If anyone could provide a hit of clarity or insight into this topic, please do.
there is already a thread requesting that:

here is the sensation kernel:

Dear god I wouldn't do that. The adreno 220 is a very good gpu. I think it's the fastest one commercially available.
Plus I've had a bad history with gpu overclocking. I tried overclocking my ATI 4820 and it just ended up not working at all

FYI, just about every single ROM available right now already has overclocked GPU, check the changelogs/feature lists.
well thank you for redirecting me, and i was hoping somebody would have made some sort of app as was done for the Samsung GSII, but thank you nonetheless

From every ROM I've ever seen they never say the GPU has been overclocked. That requires Kernel modified.
Everything I've seen states "GPU Tweaks" which I believe only means they've tweaked the amount of memory allocated or the MPAA settings. Which is just a simple prop edit.

roms cant overclock the GPU - it is overclocked in the kernel - most roms use stock kernel.
im working on a kernel now to OC the GPU to qualcomm spec. (so its not really being overclocked - but it is abt 40mhz faster than HTC spec)

sometimes I post drivel

how is this thread going ?
I would really much like to see the possibility to overclock the adreno 220 because I think we can gain a lot of preformance in games etc..
hope someone looks in to it
Actually that isn't over clocking at all. Thats the normal speed. Htc under clocked it on us.

qualcomm spec was 320MHz max (for HW001 and HW002)
i have 2 kernels - 1 @ 300 and 1 @ 320
How the andrino 220 stack up now,compare to the iphone 4S one and the mali 400,any answers will be greatly appreciated.
I am looking to buy a new phone,i don't like iphones,my current one is a Vibrant,so i am thinking about the Galaxys 2 from T mobile.
But since it use a 1.5 qualcoom cpu and andreno 220 GPU i don't know,since i don't know that GPU well,i don't know if it is weak or not,i love the Vibrant GPU it was quite ahead of anything until the Tegra 2 arrived.
Let's summarize for a second here:
The Qualcomm CPU is built for 1.5GHz, but underclocked to 1.2 GHz to save on battery and heat.
The Adreno 220 is underclocked to save on battery and heat.
The Adreno 220 is anywhere from ~5-50% faster than the Tegra 2 dependent on the benchmark/utility/application
The Adreno 220 (even underclocked) will perform so well that any mobile game out today will run without any perceived negative performance that is humanly detectible.
The Adreno 220 performs so well that the above will still be true for any mobile game that comes out between now and the time you get your next device
With the above facts true, there is effectively zero reason to currently want or need to overclock the GPU. What reason did you have to want to? Just to say you did? The way I see it the perceived benefits can't possibly outweigh the risks. I'm not sure (without doing the research) but I believe the Adreno 220 is still the best performing GPU on the market.

I have see some performance test and at least vs the Mali 400 which the other galaxy have is actually the slowest,i actually have read some reviews that say the T mobile one is the weakest performance wise thanks to the Adreno 220,but saw some text in which the Adreno was faster than the Tegra 2.
Since i am looking to buy a T mobile galaxy S i am trying to get the most research to see if i get it or not.
There is a bit of difference in my games when I OC'ed the CPU from 1GHz to 1.19GHz
But what about the GPU? If you overclock this you definitely can play games without lag. Did anyone ever try it out?
From my research, it cannot be done with a software based OC. In other words the combination of all the Streak's hardware is the limiting factor here.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Does anyone know how to overclock the GPU (NOT THE CPU)?
I don't think it can be done with snapdragons

Bringing this thread back from the dead cause I am too interested in doing this.
I have read up on other phones that have had developers make kernels where this is possible, although to little or no "concrete" evidence it actually works. But from reading up on our phone, it does have a snapdragon processor but states it also have an Adreno 220 GPU as well. Wouldnt this mean they are seperate? I dont consider myself a czar of phone hardware, so I of course could be mistaken. I also read that this GPU is really an underclocked Adreno 225 and is capable of being overclocked to 400Mhz (from its standard 200Mhz state) with no problems. I would really like to see if theres a difference in gpu performance, but I am in no position or knowlegdeable enough to firgure it out myself. If there was anyone that can figure this out I think it could be sweet if it made a difference.

Put all these thoughts on hold for now. Until we have custom kernels available, none of this is possible.
custom kermels do it automatically. I have yet to see an app that does it with stability. I remember the incredikernal and app sorta did for original inc. chad would most likely be the man to possibly pull it off at some pointw
is there any option to raise SGS3 CPU to 2000mhz or something like that?
EDIT: NEW AS 14/7
kk so i guess the highest and most stablest cpu might be till 1800mhz
1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)
2what about GPU?
not yet, i think the highest clock right now is 1.5 for the sgs3
and RAM, NO you can not get MORE ram, you can eliminate apps that eating up ram to free some up but no way to get more ram.
is there any need to overclock this beast lol its fast enough

He wasn't referring to getting more RAM though was he? It read to me that he wanted to see if was possible to increase the clock speed of the RAM along with the CPU.
yep just wondering if there is any option for that as in SGS1+2
do you guys think when there is OC for s3, it will raise CPU to 2000MHz ?

Already there OC/UV running 1500Mhz right now. Max 1800Mhz.
Look into de developers topics for the kernel..
Ive looked there.. stiil misunderstand something-
there is any OC of 2000mhz now?
Note that the Exynos 4Core CPU is still not very well understood and may well get long-time damage when ramping up the clock speed aggressively.
Is there actually ANY need for going so high except to show off?
You'll be measuring any speed improvement in loading things up in microseconds because people say Samsung still hasn't fully optimised the phone to the OS yet, so I think it's a bit pointless stressing the phone that much.
1.8GHZ is currently the max however with kmemhelper you should be able to change the last frequency to 2.0...
Hell I'll even find out the script for you if you are mad enough to try it first

I doubt you'll get it 2GHz stable anyway. From what I've heard most people have theirs crap out at 1.8GHz.

1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)

to make it clear:
i wanna know which ram overclocking is available to do on the SGS3 as long as the device still stables.
same with GPU and all those stuff.. there is a really good lvl of OC like in S1 S2?
still waiting for help
I would go for Siyah kernel and try 1.8 GHz then under volt using voltage control or extweaks app. Most phones can go 100 mv on all steps except maybe the very highest clocks.
gpu overclock is not possible yet

OC of the ram is connected to bus speed and this is very different to the fixed bus in the sgs1 so nothing like live oc is possible. Still 400 mhz bus speed is 4 times faster than the CHAt!
Sent from my GT-I9300 using xda premium
I`am running RGUI v7 rom and siyah kernel 1.3.8a. My clockspeed is 1600 Mhz and is rockstable, snappy and battery life is great.
I don`t go any higher for daily use, it doesn`t make much difference in speed and i think it cuts down your cpu-life.
ho so no LIVE OC is available now? (like in S1 and s2)?
well hoping it will be possible to add those functions(live oc, ram, cpu, and more..) in Android JB 4.1
My Captivate (SGS1) can hit 1.92GHz... So I think that a CPU with a stock clock of 1.4GHz can hit 2GHz easily. We will just have to see. I am not pushing this phone though. I don't have $700 to replace it.

That's not depended on the ROM but on whether the hardware allows to modify the values and if kernel developers figure out how to do it.
Ok i searched google and here but didnt find a decent answer..
its just noob questions but i hope you guys could give me simple answers..
1. apart from getting better battery life, what's the difference between 1.2ghz with no undervolt and 1.2ghz with, let's say, -50mv undervolt?? what's the advantage/disadvantage?
2. what's better for performance/battery, 800mhz no undervolt or 1.2ghz with -50mv undervolt?
3. what's the gpu for? is it for games only?
4. is the cpu or gpu which controls the browser, i mean for rendering web pages/images/videos? for example, if i set the gpu to the lowest possible tweaks and underclock it will it affect how fast the browser render pages?
I hope you bare with me, it's been a really long time i want to ask these and find answers..

1)If you undervolt the CPU Core(s) gets less power, which is better for battery life, but maybe will decrease performance @ this CPU step
2)Performance: for sure 1.2Ghz (800Mhz is less than the Galaxy S )
Battery: you have to find out yourself which Kernel/ROM/CPU-config fits best for you!
3)The GPU is for everything grafical in some way (especially for Games etc.)
4)Maybe...
I really don't know but I don't think only the GPU "renders" webpages
