[REQUEST] Tegra GPU OC....

Hey everyone...I tell ya, I sure am enjoying all these awesome custom roms and kernels. Great job to all the developers here, putting in the blood, sweat, and tears for the advancement of the community, thank you so much. One feature that I saw in a Xoom build was the GPU overclocked, and while I'm sure it won't interest everyone, and there is probably only little gain to be had from it, I would love to have the option to oc the CPU and the GPU for the highest performance possible...please. Well I think that covers it unless someone else shares my desire to see this feature. Thanks for all your work and consideration XDA and have a great day.

if ur CPU OC than GPU too

Apparently not so on the Motorola Xoom as there are two versions of Tiamat 1.4.4... with and without GPU OC. Tiamat 1.4.4 Full Throttle

oc-ing the gpu doesnt get you anything... gpu is default 200mhz 2d with 300mhz in 3d and it can be uped to 250mhz 2d and 400mhz 3d but it cant be software controlled and it will eat more power...
and no oc-ing the cpu doesn't oc the gpu, its a separate part of the tegra2 processor

Hey Thor, thanks for joining the conversation. Based on what youve seen so far, how well are the tegra GPU cores being utilized? Suffice to say I've pulled off insane desktop GPU overclocks that showed almost nill gain with drivers that werent mature in which the GPU cores werent being loaded past 50% . I realize that the tegra is a horse of a different color, but isnt it still affected by the specific driver optimizations, hence the THD enhancements? Just out of curiosity as I very much trust your experience. I am still interested in trying it with definitive comparisons to follow...well about as definitive as synthetic benchmarks can be anyway.
I just saw that you have a new beta... Yay. I cant wait to give it a whirl.

I have been over locked for a little while. Max I have done is 1506 but it tends to be slightly unstable. I run 1400 now and haven't had any issues. biggest difference I notice is home screen transitions load fast and don't lag and programs load much quicker. there doesnt seem to be any games that will push the CPU hard so I don't notice much of a difference there.

I've had 1600mhz going strong with no instability, benchmark after benchmark, the only issue I've had is the device shutting down when left alone for too long, but I consider that a useful standard function. Otherwise 1600 performance has been rock solid. I decided to take it upon myself to take this girl apart' clean the CPU off, remove the thermal pad, and apply some as5....though the chip didnt really run very hot to begin with. Now until I have the option to go for 1800mhz, I'd like to see where the max threshold is for cpu/gpu oc.

I have mine overclocked also at 1600.. Runs very stable at this speed and benchmarks not too bad:

Can only the 3D Clocks be altered without touching 2D? If yes can you make such a version of the ........... that "nobody" knows anything about?

Very nice quadrant score man, I used to score alot higher until I updated to stock 3.1+ updates. It seems like the higher my OS version number gets, the lower my synthetic performance gets overall.

that's what mine did. it would reboot while sleeping. sometimes it would be 3 or 4 times in an hour.

Wow!
Umm, what rom do you guys run for this? I'm on rooted and CWMd stock 3.1 rom. Can't find a OC kernel for it. Only one I can find is for ASUS based roms. I prefer to keep stock rom if it's possible.

You should try richardtrip's kernel. His kernel is keep updating Very good performance and stability.

thats the kernel i am using o/c 1400 works very well. you can find it in the development thread.

Thanks! Works great. Do you feel the HoneyVillian rom runs faster with the v2.4 Kernel or about the same as stock Acer 3.1 HC rom with v2.4 Kernel?
So far I can keep stable at 1.5 after 2 hours of use. It's also slept for 30 mins and seems ok at that too.
Also what kind of Scaling do you guys use? Ondeman, Interactive? On my phone I use ondemand.

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 .

Isn't it SOC? As you overclock cpu gpu is overclocked also?

Good point . But couldn't that lead to more problems ? Too high of gpu could cause failure in stability but the CPU can handle the high oc ?

yea i really wouldnt recommend touching that, as far i remember we are already running diff os's that stretch are gpu and cpu with hacks and kernels etc....

How are your benchmarks so high?

It's been about a year since any benchmarking threads have been created for the A500, and I'm interested to see how people are getting better performance.
I'm running Flexreaper v5 and I score around 6200 in AnTuTu. One other ROMs and other kernels I'm getting around 4300. However, the AnTuTu comparison charts show quite a few people scoring 7500+ with the A500.
How are people getting such high results?

Overclocking maybe?

Hoping for something a bit more specific. Kernel, ROM, CPU Frequency...
BTW - Mine is OCed to 1.5 GHz

Think I found one of the ROMs that's getting such high performance. I got the JB ROM from he would cannot be named, and this thing flies! 5600 in AnTuTu with no OC. Set GPU to 400 MHz and OC'ed CPU to 1.6 GHz, and that clocked in at 7225.

I'd be a little careful at 1.6. Runs a little unstable, and is only for benchmarks.

It looks like the new kernel allows clocking up to 1.68, so I have just left it at an even 1.6. I haven't run into any major instability so far (knock on wood), and I really like how smooth it is. I've finally been able to play Asphalt 7 smoothly (good way to blow off steam at work). Thanks, though.

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.

Is there any way to overclock the gpu for Galaxy Tab 4 7.0 (sm-t230nu)

I found a thread here xda about how to overclock the cpu Galaxy Tab 4 7.0 (sm-t23nu). In that thread the creator of that custom kernel had a problem increasing the frequency of the cpu when it came to 1.4 Ghz (version 2.2 kernel) because it appear more laggy. He then later made other version of that custom kernel that was down clocked to 1.3 ghz. So I actually tried the older version it was fast but what I noticed was that cpu was going really fast(everything open up quicker apps processes were getting done more quickly) but the gpu it self was bottleneck the cpu. I noticed that because when game with it that and everything was going smooth and fast but the rendering of the image was struggling to catch up. So I install aida64 on my tablet to see how much Mhz the gpu going at 416 Mhz stock speed but what I really found interesting was that it's not even going at it's maximum stock speed which 533 mhz so it can literally overclock to 533 Mhz and still have headroom for a 5-10% overclock which could be about 650 Mhz. So I was wondering if there's any way to overclock the gpu for this particular tablet. Thank you in advance

Hey
I too create custom kernels for this specific tab and let me tell ya it's a big pain...u can overclock the gpu but it requires changing alot. You have to change the plls the gpu runs on and on top of that it breaks the frequencies the cpu runs on and also the gpu info doesn't show up at all so if u plan on building pull the repository for the tab 3 which uses the same chipset. Then go to the files that are related to to the gpu which all I did was delte the gpu folder and replace it with the tab 3's galore file which will allow u to see the gpu info in kernel aduitor etc etc. Also one more thing I have a kernel with it overclock to what I believe is 1.6ghz.. and the gpu is capale at overclock ed frequency of 832 mhz
Good luck!!!

But that's problem I don't know how plls (what are even plls?) of the gpu? Plus I tried searching out on xda and other sites on how to edit kernel on overclocking frequency on both cpu and gpu but there's barely information how to do so and the only thing I know is that every kernel has different ways of changing frequency within different kernels so it's not the same for usually most of the time. XDA only shows how to add scheduler and cpu frequency also it's very general idea but in the gpu side there's no information about it. Can you give me advice what program I should for editing kernels clock frequency of cpu and gpu? Also where can I learn to edit the kernel for the galaxy tab 4 7.0?

my tab 4 7.0 is 1183 mhz, and yours is half of it? whaaat??

??? 1183 MHz ??!! How did you manage that ?? Mine is at max 533 MHz .... , checking the forum like crazy how to increase the GPU MHz range . Like OP mentioned , CPU already @ 1.4 GHz instead of the default 1.2 GHz quad core speed . But seems that the GPU can't catch up : result rendering images on high end games are slow ( hangs , laggy ) .

Yeah because the cpu is doing everything fast while gpu is like snail due to the low frequency and graphical api (OpenGL 2.0) it has which can not be fixed for api but tweaking the gpu to higher frequency could help alot in cpu overclocking. It would be better if it had OpenGL ES 3.0.

I can't really tell if you are joking or not because you're a senior member and should know this but what i'm talking is GPU-Graphic Proccesing Unit and you are talking about is CPU- Central Proccesing Unit. That's stock frequency of the cpu for that tablet mines also used to be 1183 Mhz in cpu frequency and now I overclock 1.344 Ghz. The problem is when I try to go to 1.4 Ghz the cpu is very fast at proccesing information I can literally have 10 or more tabs in google and multi task and it super fast compare to stock speeds but when I see video or game on it lags because there's a bottleneck with the gpu.
