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

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.

Nvidia tegra 2 GPU overclock

After some search in this propose I have found that Motorola xoom developers sucedded to overclock the GPU by 33% whick means clock speed of (442.89 ) mhz instead of stock (333mhz ) and a big boost in speed , knowing that we have same processor like the motorola Xoom can any developer here do this GPU overclock ,or should I post this thread in development thread .

this is a question about development so you put it in the right spot.

Sweet!! Let's see if we can get this for our GT's!

Maybe u could would like us to create the pershoot kernel?

I'm not a kernel developer ,I created this thread to. Get the attention of the developers to do the gpu overclock. In case they. Haven't Heard About it.

It is about the GPU, not the processor!
And no..... imo it's not necessary...BUT the important thing is that you CAN do stuff like that on android (along with tons of other tweaks as you know already).. And it is fun!!! (although there is always the risc of bricking ) Android rocks!!!

i don't think so , the problem with 1080p videos is not hardware related , it is with the drivers support for tegra 2 , the tegra 2 hardware accelerates certain format of 1080 p videos , but doesn't support others so some 1080p plays smooth and others don't , anyway i will asko on the motorola xoom forum if the gpu overclock helped them with that .

I might be wrong but the tab's screen resolution isn't capable of 1080p.

yes you are right it is a little higher than the 720p resolution but this has nothing to do with 1080p video playback the original galaxy tab 7 has (1024 x 600 ) screen and can play any 1080 p video

The tablet screen may not play 1080p, but when using HDMI out to a TV or other monitor, it would be nice to be able to output 1080p then...

Definitely would be appreciated to see task work his voodoo and incorporate this in his roms. That guy is talented!!!

I guess it's almost impossible to play ALL 1080p videos with the gpu. But it may be possible to play it with a fast software player. Did anyone try the Android VLC?
edit: just tried a vlc alpha. works, but only a few secs and veeerryyy sloooww - but it's possible (maybe other SW player?)

Riegos kernell actually doesent bring much of a gpu boost, so bump!

My both friends, Yoda and Google, told me about two links for the issue GPU overclocking:
one + two (the dev link for two)
https://market.android.com/details?id=com.tegrak.overclock.ultimate&hl=en

I didn't really see anything about overclocking the Galaxy Tab GPU. The first link provides stock comparisons, the second references the original galaxy tab, not the new one (if you look at the developer's site).

The hardware should allow us to watch 1080p movies but the software dosnt use the hole hardware. so we have to wait till the software is able to use the hole hardware. thats my opinion.
Edit says: RieGo stopt to implement GPU OC because it is to unstable. "dosnt work"

Android 4.0 ROM?

Can we dream of such a ROM?
Or did it turn out to be too much hardware dependent/too much broken features if ported etc..?
Also, will the USB accessories support will enable the use of an app that will let me use my X8 as a secondary USB monitor?

x8 can run ics!
http://forum.xda-developers.com/showthread.php?t=1362557

Correct if I am wrong, but doesn't the x8 has a single CPU with no GPU and that means it doesn't do hardware acceleration?
I think the lag issue with the UI would be a dead end.

x8 has got a gpu, it has adreno 200 if i'm not wrong

Water cooling?

Water cooled would be soo awesome !

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!

Wait, what? Lupus Kernel offers increased amount of VRAM?

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?

Can you post some benchmarks for the CPU? And also tell us more about the VRAM... Did it make any difference?

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.

I CBF screen shooting but CPU at 2.1 is around 20% faster then 1.6 and the GPU is around 25% faster with a 2600 3d score in antutu without adrenobooster

I know it's kind of not allowed to redistribute this but can u upload the kernel and send it ti me (PM) cus I will take some screens ans my play can handle 2GHz fine but bootloops when gaming after about 30-50 minutwa (depends on intensity of game!)
