GPU overclocking

Vogue GPU overclock
Changes that were made can be found here
That's a MSM7k device, we have a MSM7kA device which has a slightly higher stock GPU clock at 256mhz(actually the driver lists it at 128mhz, lol wtf) compared to the non A devices 128mhz(downclocked to 100mhz).
Chances of a few small edits gettings this to work? likely.

The GPU in the 7x00A is very similar to the one in the 7x00 so it should be possible but you will need to talk to your kernel devs to add this functionality.

I'll tinker around but I would love multiple people on this
EDIT: Whoops, wrong forum. Can a MOD move this to Development?

Holy...
Why even buy an EVO? This, plus AOSP, plus overclock CPU.... Then we'll undervolt it (which I'm surprised hasn't happened yet given that the EVO already has undervolted ROMS).... I love my Hero and I love this community

where do we get this and how do we apply it. Good work on this find decadence

Im looking into this right now.. But im so tired its not even funny. This will give me something to do with my time off tomorrow.
Ill compile a kernel with it undervolted as well and see how well it works when booted. I think i actually have one somewhere on my linux boot up.

anything further on this?

If anything, can you try and get the undervolt first? It would be nice to have more battery life before killing it all on an OC GPU xD But I'm glad to know that it shouldn't be too hard

YES!!!! I'm going to try this ASAP. Is it a flashable zip or no? And does the cpu still scale (can OC)? Sorry Im tired haha.
Edit
nvm that. I just flashed it, and according to uname -a, it is #15 like you said. So far, the boot's fine. Any way I can check the undervolt is working?
Aaaaaaaand she booted xD Nice work Darch!

I'm very excited by this prospect. Like had been said, why buy an evo, especially when it's capped at 30 fps. I bet we get close to 40 with this!

This would be something I would be willing to donate for if it has any chance of working successfully

I am getting 21.7 FPS with this kernel. But I am not sure that he has done a whole lot to it to make it go Zoom Zoom.

so i flashed this over buufed 2.0b, hopefully it works i'll let you know results
well i flashed and booted up fine,

while running this for 10 minutes my battery took a **** on itself, dropping 6% in under 10 minutes of extremely light use. gahhhhhhhh

Im guessing everyone is talking about what Darch posted??

yupp, my battery somewhat stablized but i havent noticed much of an increase, :/ meh

Yeah, how about back on topic here. Lol although I love the under volt. Lol. But any of you brilliant kernel guys try the gpu part yet?

Ok well I figured where our driver identifies the clock settings:
But i'm not sure where the settings come from?
http://github.com/darchstar/CdMa-HeRoC-2.6.29/blob/master/drivers/video/msm/gpu/kgsl/kgsl.c
Line 130:
Code:
static void kgsl_clk_enable(void)
{
clk_set_rate(kgsl_driver.ebi1_clk, 128000000);
clk_enable(kgsl_driver.imem_clk);
clk_enable(kgsl_driver.grp_clk);
#ifdef CONFIG_ARCH_MSM7227
clk_enable(kgsl_driver.grp_pclk);
#endif
}
Then kgsl.h would contain the struct for this: http://github.com/darchstar/CdMa-HeRoC-2.6.29/blob/master/drivers/video/msm/gpu/kgsl/kgsl.h
If I'm not mistaken.

So who do i need to beg to make this happen?!

I think at this point Darch is the only one left who can do something of this magnitude.

I dont think darch could do it.. He is smart and can figure a lot out. But we would either have to do a lot of trial and error or get toasts to look into it. He still does small work on the hero and im sure what he learns from the hero he could implement it to the Evo.

Anyone else feel like overclocking is just a gimmick

Maybe its just me but I feel like overclocking our phones is unnecessary. It seems like its just for boostin benchmark scores and it doesn't really affect real world performance. For me I used setcpu and it makes the phone slower and laggy when on conservative. Is that just setcpu not playing nice with my phone?
Tapatalkin it from my Epic 4G

Overclocking, for most part, is all about getting the most you can out of what you have. For some its a numbers game, for others it's just because you can. Personally, I like at least having the option open. However, my Epic doesn't like 1.2ghz.
Stock speeds are enough most of the time. I don't usually run the programs that use 100% of the cpu, so I really don't need to worry about it. Though, if I had the capability to OC.. I would.
As for setcpu, I've never experienced any overly excessive lag or anything brought about by its use. Though, by its nature it will be slightly slower to respond.

Coming from a hero, i can tell you overclocking is certainly not a gimmick! It may not be as necessary on these epic cause its crazy-awesome fast from the box, but it still helps. I keep mine at 1.6ghz on conservative, and performance when i play certain games. For me its about the multi-tasking improvment. Also i like to see my icons fade in smooth no matter what i have going on in the phone
But for me at least, its far more than just a benchmark score. However it is pretty sweet telling my iphone rocking coworkers to eat my ghz

Well first it depends completely on your phone, all are different in terms of what they can handle, so each individual phone will respond differently to overclocking/undervolting. I can personally run 1.2, 1.3, and the 1.6 completely fine, while a lot of people can't run any of these. In terms of performance, it does make a difference with animation speeds, fps on games such as pocket legends or angry birds, and overall lagginess. But again, this is dependant on your phone.

I flashed the Xtreme kernel today but for some reason, I'm not getting the FPS unlock. Nenamark and Neocore are not getting the +70 I was expecting...

Are you running v1.2.0? If so, the fps cap is not fixed on this version because Devin removed the 1.6ghz step which allows the framerate to be raised. It works on some phones, but not all which is why he removed it.

That explains it

The same argument comes up every once in a while concerning PC overclocking. I admit the phone overclocking has yet less benefits and even more downsides, but oh well, it's still super neato.

Exactly, you have to compare this to pc overclocking because it is the same exact thing. Two processors of the same make and model will overclock differently no matter what, it depends entirely on the die. Correct, the benefits are less noticeable, but it still makes a difference.

There is a notable difference with stock 1ghz and a 1.2ghz. 1.2 - 1.3 isn't worth it in real world that's bragging rights

Dude I know lol. I have a rooted hero, but im sick of all the custom bs. I want to underclock and thats it!

[Q] Tips on getting a better speed on my Vibrant??

I have a Vibrant rooted running the Team Whiskey Bionix-v1.2.1 ROM. I have a few apps that I use daily, but the only one I know does any major damage to speed is beautiful widgets. I don't use any live backgrounds. I scored a 1536 on a benchmark test from Quadrant Standard.
Do you guys know of ways to better these scores?

Use AutoKiller Memory Optimizer

Unless your phone actually feels sluggish I wouldnt worry about quadrant scores. If it is sluggish try installing Voodoo or one of the Universal Lagfix in the developers section.

With a 1500+ quadrant he's already running Voodoo...
I do agree that unless the phone is feeling slow to not worry about it. Quadrant is pretty easy to fudge over 2k even though the phone isn't any faster.

Didn't wana assume lol..

Haha yes I have voodoo, bionix-v1.2.1 comes with it preset. Appreciate the help.

actually, if you going for score some of the older J-rom series with over clock really scored high........ But with the current setup, you typically have 11-15 or so things that are open and TSR, if you remove alot of those to make it a vanilla barebones, then o.c it...... you can improve the score........ BUT speed scores are not worth much other than bragging rights.......... Like everyone else said if your phone is performing well then,..........who cares about the scores

Yea I'm just trying to see if there are things I can do to make it perform even better than it already is

Go look up the Dragon 3.6 Kernel in the Dev section. You can overclock the phone a little or a lot depending how much it can handle. I'm running 1.2ghz at the moment.

Stock 2.2.1 is the fastest/smoothest ROM I've used on this phone ever and it hasn't even been optimized. I also downloaded the Dragon Kernel v3.6 and overclocked it to 1.28Ghz and its very stable. I always use my friends iPhone 4 to compare speeds and with the current setup I have now their isn't any difference in speed.

{req} gpu uv/uc

Been trying the SGSII for a while, and came across a great feature introduced by the devs, were u can OC/UC and OV/UV the GPU just like the CPU.
I would like to know if it's possible to do the same for the NexusS?
I'm mostly interested in UV/UC as most people know that the PowerVR SGX540 is extraordinarily powerful.
If it's possible and other members are interested, i may start a bounty thread.
Many thnx

As far as I know he only rapes increases the bus speeds.

overclocking the note 3

the note 3 is already fast as hell, buuuuut lets just go ahead and say that some of us are speed demons, would it be a bad idea to overclock the cpu on the note? or would that just be over kill and mess the phone up?

you can't OC it unless you have a developer edition with changeable kernels (although I can't imagine why you would want to)

LOL, I'm sure it does although I always find that kernels are more of a placebo than anything. (and I've run every kernel known to man at one time or another).
In all my years of running them, I invariably find that no matter how overclocked/undervolted etc.etc.etc. that although they are certainly fun to play with, the system always runs just as good for everyday use with the stock kernel the system came with.

I agree that oc'ing/undervolting this beast would be worth it....it's kinda like why not? it'll be a noticable difference i predict
