Overclocking the Mali GPU - Galaxy S II General

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

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.

[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

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.

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...

HTC Titans CPU versus HTC Desire HD CPU (MSM8255)

Hello everyone!
I've been looking on the web for some time now about the new HTC Titans CPU,
clocked at 1.5GHz, named as Scorpion MSM8255 (same as ours (DHDs CPU)).
What do you guys think about it? Since our MSM8255 can "officialy" only hit 1GHz,
but now HTCs new MSM8255 can get it to 1.5GHz?!
I've searched the wiki also and i cannot find any differences.
Oh wait, is it that T at the end maybe? Just found it now.
HTC Titan: MSM8255T
Okay, so anyone know more about this? Feel free to comment
It's the same chipset. HTC did the same on the Flyer. They just OCed the cpu to 1.5 GHz since the cpu can handle it without problems.

How easy is it to actually oc the dhd cpu and is it really wise?
Sent from my HTC Desire HD using xda premium
A fellow Bristolian! Hi!
How easy? Very. 1.3GHz is achievable on the DHD with stock volts (1.1V). Wise? Yeah, anything up to around 1.2V is sensible, and safe is far beyond that.
To be honest, nobody will need to go past 1.3GHz, virtually all ROMs run smoothly at that clock.
Haha hey nice surprise lol
Oh sounds good. Pretty new to this only just rooted and flashed custom ROM the other day. Wasn't sure if I should OC or not tho. Guessing it's going to reduce an already poor battery life haha

I've had mine at 2GHz. I clocked it down to 1,3GHz after 10 minutes since it got REALLY hot. But it managed to run just fine at that speed.

Well, all of the kernels undervolt as well. Almost all of them run the processor at 1.2GHz at stock voltage. So overclocking shouldn't shorten battery life. Also, remember that many of the ROMs have andrev or virtuous OC daemons installed, so they will be underclocked to minimum speed most of the time. So either way, battery life and performance will be improved.
As for overclocking to 2GHz, while it is possible, I'd very strongly suggest you don't do so.
But it does prove that firstly, the MSM8255 is very overclockable, unlike the larger processed chip in the Desire (which I think will really go as far as 1.2GHz only, correct me if I'm wrong...). The Flyer's processor is exactly the same, just selected (a process called binning) because it is "capable" of running at that speed at the required, and desired voltages with the required stability that the manufacturer (Qualcomm) wants.

Thanks for the reply. I'm currently using rcmix runnymede ROM and its not oc'd. Would a OC of 1.3 be wise on stock voltages?
Sent from my HTC Desire HD using xda premium
1.3 might be pushing it. Mine needs 1.125V to be stable. I'd suggest that you probably do the same just in case, or even better 1.150.
The safest thing to do is take a look at the NCTeam kernel voltages, and use those (use IncrediControl from the Market to change voltages). They should work for virtually everybody. 1.3GHz is the speed I needed on Sense ROMs to be very smooth, you might find it is less though.
The desire hd doesnt actually overheat much @ 1.3ghz (I use that + Performance governor when playing some games), so the CPU can probably be overclocked quite alot without any problems
Other phones overheat quite a bit @ stock speeds...
Mine is set to 1,6GHz and it can handle 3d gaming for hours with the case only getting a bit warm. I wrote in a different thread that WP7 is getting an update and it will be able to run on DHD hardware. Maybe some devs will be interested in porting it to DHD then. It would be nice to dual boot Android and WP7. I can almost see all iPhone users faces.

Just to make sure I was clear, I meant that 1.3GHz could be pushing it on stock voltage, not that it could be pushing the limits of the chipset for speed. I think everyone got that, and knows that, but was just making sure.
As for heat, my phone didn't even heat up at 1.3GHz. You can push very far with no problems.

Don't forget that we need a wp7 bootloader. The android one can't handle wp7. Furthermore we probably have to repartition our internal memory (or sdcard if you want to run it from there) since wp7 uses other partitions than android (not sure about that, but i guess we have to.)

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 .

there is a theory by turgot, that increasing a faktor wont increase the outcome at a specific point anymore. therefore i would be really interested how your play handles games at that oc. not only a benchmark, something like a video where its possible to see occouring errors, if there are any
this is great work you did, and it may allows some modification to the play.yes im thinking about cooling..even if it wont be that portable anymore. thanks for your help
2.3GHz
I'm currently going where no developer would go before my customized kernel has 26 CPU frequinces all up and a max of 2.3GHz
But without the GPU overclock and a 8mb GPU memory vs Lupus and dooms 4mb
i cant go even more than 1.6ghz
Needed an extra cooler solution and an powerful battery, like Mugen 3600mAh, to maintain this level of OC for diary use. Would be amazing!

IMHO this is perfectly fine if you don't care so much about the device, otherwise you would be crazy. OC'ng so high will eventually cause in-reversable damage. I know what your doing so no need for me to ask questions But even if its stable for you it wont be for others all depends on the chip and as we know each is different. Also even if people don't use 2.x ghz frequencies tend to jump to the highest for a mili second if even on boot, causing problems with the device actually booting.
Well just my 2 cents on OC'ing...

What about 2 cents on this VRAM apparently being doubled?
At the end of the day its not GMEM which is essentially like a processors cache. Our chip has 256kb of it. But the allocated VMEM, would upping it to 8MB provide any sort of performance increase?

I believe that the Xplay has good chances of reach 2.0GHZ, running fine, provided has an good thermal solution. In my test, the games run fine for some minutes, before start overheat. Needed of somebody to build an custom cooler, then, make some tests. In my opinion, the safe clock, for sure, is not only 1.6GHZ. Only for default cooler.
