GPU overclock kernel for ICS

If the SGX540 in P1000 can be overclocked to 370MHz, the performance of it can be highly improved like in Overcome Kernel.
(Can be showed in Quadrant Standard Edition. When it is in 370 MHz, the fps in the graphic animation of DNA can be promoted to 60fps. And got no lagging in anything. The speed(smoothness is nearly reached S2 which is official 2.3.6)
But however, it doesn't seem that any ICS supporting kernel can set the clock of GPU.
I am sorry that my English is not good enough to represent my idea, but I hope you can get what I am talking about.
And the most reason I want it to be real is that the potential of P1000 is quite big and in fact it is quite good!
PS Antutu SetCPU app can set GPU clock in Overcome Kernel.

Dang, I never knew that our GPU can be overclocked ^^
since this tab is getting old, maybe its time to overclock the gpu also?
Personally I'm agree with this

Probs a little off topic, (also to bump this up a bit)
But the Gnex which uses the same GPU can be overclocked to 512Mhz (Stock is 300 something I think), improvement seems noticeable in apps and in nenamark, you go from 27-28ish FPS to 31-32.
It would really help the tab, it seems to show age now (which makes me lust over a 7.7......)

What I knew is the potential of SGX540 in GNexus and GT are different.
GT one is 200MHz and GNexus one is 374MHz.
In Overcome Kernel w/ GT, the clock of SGX540 can be set to 370~38X Mhz w/ no crush but when it is 400MHz , the machine is seemed to be lagged.
The benchmark in Overcome 4.1 plus Overcome Kernel 4.0 can be promoted over the GT 7.7 (of course the mark doesn't represent the real using experience but let's just look at the 3D mark)

Haha, yea I know they have different potentials Just that I thought I'd let you guys know how much better overclocking the GPU would be.
I think its worth it, there is little impact on battery life, but the improvements in apps and usage are noticeable.

I think the battery usage for extra cost of GPU is not as high as CPU.
It is being a great difference if we compared the overclocking for either CPU and GPU.
The consumption of GPU is low and it won't make the device hot as CPU overclocking.
And the temperature can keep around 35 to 36 degree Celsius under a room temperature 20 Degree Celsius.
The result screenshot I have posted is undergoing CPU overclocked (1.4GHz) plus GPU overclocked(370MHz) w/ overcome kernel and rom.

Success!!!

Hello, i have been trying to implement LiveOC into humberos's kernel and it is a success
LiveOC
This allows us to modify the bus speed which increase both the cpu and gpu clock at the same time using an app called NStools
i have only been using this for a day now and it seems to be working very well
please report back any bugs thank you,
BTW i will post the settings i have used in NStools and this kernel is for the latest MTD build
Link: http://www.4shared.com/file/216rF_WJ/boot.html?
My settings:
Governor: smartassV2
min CPU freq: 200MHz (240MHz after applying OC Value)
Max CPU freq: 1000MHz (1200MHz after applying OC Value)
OC target low: 200MHz
OC target high: 1000MHz
OC Value: 120%

I'll give that a try when I get home (or maybe a few days later). So which ICS rom did you try this on?
EDIT: In terms of quadrant (which I know can be a bit volatile... but a nice way/quick way to see differences), ICS gets a lower mem score :< 3d is slightly lower, 2d is about double (I suspect thats forcing 2d rendering). This is comparing the gtab score in quadrant, I haven't used GB on my tab for a longgg time...)

thanks for the information
as a newbie, i just thought another aokp by stimpz0r is identical
there is a strange point which is the fc of the camera while the shutter sound is closed, but it works while enabling the shutter sound
It is a great rom and thank you for your great work

[Q] CM9 performance i9001

Hi everyone,
I had installed CM9 RC2 by ivendors and it's graet
there is some lag using UI and it's very slow loading cantacts.
How can I increase performance? now i check only 16bit transparentcy.
thanks
Carlo

Use CastagnaIT's kernel and adreno jelly beam drivers from galaxy w.
Smooth UI, all games work well, 4400 antutu score @ 1.4Ghz and smartassV2
Do not use app killers and manual kill only aps that you don't use often.
Good luck and Pm if you need links.

[Q] About Performance From OC'ing Kernels.

Okay I have been debating on which kernel to use for the CM10 ROM I use, some of them like m-kernel support CPU/GPU OC'ing up to like 1.7GHz then other kernels like franco support the same, but don't allow an OC above stock. How much performance gain for sacrifice of battery life do you truly get from OC'ing your CPU to a higher frequency, compared to just overclocking your GPU?

I can't notice a big difference in my use with the OC CPU . The GPU OC is more noticeable for me. I run trinity kernel at 1150 CPU 446 gpu and it runs great.

I'd use something like AnTuTu over Quadrant just because I find it more reliable tbh.

benchmark lovers

while I realize that many people hate benchmarks the truth in my humble opinion as a windows hacker and android enthusiast is that benchmarks, run properly, can tell you a whole lot. there is some variances but usually that is from screen brightness settings, running at different core temps, background apps, widgets, and waving the accelerometer around like you just don't care lol. and you can say all you want to synthetic means nothing but the fact is even manufacturer's use benchmarks in their testing of new chips as well. just look at the current benchmarks from sd 600 vs sd 800 from qualcom. so I have decided to carefully benchmark every kernel myself to find what gives ME the best user expieriance. maybe it will help the dev's, maybe not. maybe it will help you, maybe you hate my dog and want to skin my cat.
a benchmark can tell you how well the kernel makes use of the hardware so for testing purposes I have used stock rom on all tests. I have set up my cold box for testing so that the cpu and gpu do not suffer and return quickly to normal and have set brightness at 50. testing is done stationary against the back of the cold box proped so that cool air flows over the systemboard. for testing purposes there is only the stock clock widget and micro cpu monitor and a few battery temp/sytem stats apps running. after each benchmark the tablet memory was swept. all benchmarks were run 3 times and the highest score given is used here unless there was a wild varient and then it was tracked down and all benches ran again. after contemplating it i ran some of these plugged up to the ac on my cold box and sometimes i forgot to plug it up. and some using debugging but i honestly doubt that had an effect. so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
im also not really comparing custom kernels to one another but I do to stock kernel, every last one of them are great and offer a lot of features you cant get with stock. all offer performance above stock if the proper settings are used and the overclocks are not to extreme for the framework. they are all also still works in progress so I think they will improve with the developers attention as time goes by. i started with stock kernel and ran antutu, quadrant, velimo, 3d mark ice storm, 3d mark ice storm extreme, basemark x, gfxbench 2.7.0 t-rex hd onscreen, gfx 2.7 egypt hd onscreen
stock kernel
stock ran well and i liked it, but i hated having to long press wifi to toggle and short press takes you to settings, wtf google?
edit.... so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background

whatever flo 002 kernel
the kernel ran smooth and i liked it. i have the same complaints about it as i do stock. wtf google?
so on this kernel as you can see it functioned better than stock on every single benchmark. some were close but just a little better is...well...better.

jassy release 5 kernel
this kernel is set up to use an external kernel control app. it will not function worth a hill of beans without it in my testing. and even further than that it seems to not like trickster mod for me as it bench's higher with faux kernel control app paid version. real world expierance is good. fauxclock is set to 1.89 ghz CPU OC. cpu ondemand governor. snake charmer and mpdecision on. intelithermal at 60 and 80 respectfully. gpu at 487. gpu simple governor. fiops i/o at 512 read ahead. as you can see in cpu and gpu performance it face smashes stock kernel then kicks it while its down and makes it cry for momma. i dont know what the dude pasted into this kernel but i like it. jassy worked hard so we could have a full featured kernel that works well. release 6 = win, release 5 o yeah baby performance even ondemand. i could still kick this to performance governor lol

elementalx 0.7 kernel
settings with no external kernel control app.
1988 cpu overclock on each core. 487 gpu overclock. simple gpu governor. stock bus. stock voltage. no stw, dtw. the kernel ran well in real world performance. STW and DTW are awsome features by the way and i really like this kernel but didnt install them for testing purposes, one less potential irritation. as you can see it actually lost a bit from stock performance though in every benchmark except basemarkx and gfxbench 2.7 t rex. that tells me there is a problem with cpu performance in this kernel. also look at the cpu vs gpu in antutu vs stock kernel. so what i like this kernel and with lower clocks, dude it rocks. stw and dtw are wins.

elementalx 0.7
settings with no external control app.
1890 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus.stock voltage. no stw, no dtw. again the kernel ran well in real world performance but as you can see it took a serious hit in performance at this cpu clock setting. the gpu features continue to score high though

elementalx 0.7 kernel
settings with no external kernel control app.
1728 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus. stock voltage. no stw, dtw.
as usual really nice running and here the voltage values are more sane i guess. bested stock in every bench. i figure 1.9 ish before the poo poo hits the fan and performance benches go south rather than north. that seems about the same for the other kernels ive tested too. flar2 really has a winning kernel here with stw and dtw. highly recommend giving it a try

3flo v4 kernel
not testing this one yet as my boy doesn't even have the nexus 7 2013 but I tell ya, I got a good feeling about him. seems dedicated and excited.
Edit...he just got a mpdecision kernel booting and posting good scores but has a cores on touch problem for me. Very beta but it shows that even without a device you can build. Still got a good feeling about this one.

faux123 flo jb 4.3 001 kernel ulta
not coming. I can boot it and even run at highest settings but antutu ehh and im tired lol. maybe ill do it if the overclock structures are changed in some way but ehh not interested in this high on this chip.

faux123 flo jb 4.3 001 ES
settings. faux 123 kernel control paid version. 1.512 ghzcpu. mpdecision off. cpu governor ondemand. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400 and ondemand. fiops I/o 512 read ahead.
so here you can see again the same slight loss in gpu performance which lead to slightly lower scores than stock. cool kernel though and I do like intelli thermal so

faux123 flo jb 4.3 001 kernel mainline
settings in faux123 kernel control app paid version. 1.83 cpu OC. CPU Governor ondemand. intelliplug. mpdecision off. eco modeoff. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400. gpu governor ondemand. fiops I/o 512 read ahead.
so I found the kernel smooth in real world. I looked for my sweet spot and found it around 1.836-1.89 cpu. above that didn't really work out well for me. so in this great kernel the cpu benchmarks higher than stock but for one reason or other the gpu seems to bench lower than stock. all in all a great kernel and omg I love the idea of eco mode and I think with proper cpu governor and eco this kernel would rock some battery butt.

[Q] Octa-core Samsung Galaxy S4 caught cheating on GPU benchmarks

Octa-core Samsung Galaxy S4 caught cheating on GPU benchmarks. The real GPU Clock is 480MHz. When using benchmark, the Galaxy S4 GPU start ticking at 532MHz and continues to do so until you exit the app.
So, my question is,
How can we overclock our GPU to 532Mhz?
Maybe the devs can make the GPU always 532Mhz on Custom Rom like Cyanogenmod Rom to get the best performance?

The real GPU clock is 544MHz.

I read the article somewhere (can't give you the link because I'm new user), the real GPU is 480MHz. It only clock to 544MHz when you're running Benchmark tool such as 'Antutu Benchmark'. But after you exit the benchmark app, The GPU will clock to 480Mhz for battery saving. It will never use 544Mhz unless you're running benchmark app.
