GPU OC Test

Ok, lets get some mass testing going now just to see what happens:

TOUCHWIZ ONLY!!!!!!!!!!!!!!!!!!!!!!!!!!!

Use KTweaker to set the GPU Max. Do the 3D ONLY test 3 times at, 450, then 504, then 544, then 600 and record the highest for each step and hopefully at least the first 2 or 3 will go up, the 600 and maybe the 544 might stay the same due to heat but it seems to definetely be working for me, scored a 7400 at 544, 600 seems to be too much heat for my phone:

Still happening from time to time. Anyway, it's kinda confusing..... It doesn't start at a stock value.

My sliders say mv 1mv 1mv. If I move sliders they then go from 600mv to 1250mv. How are we supposed to undevolt if we don't know what stock is?

EDIT: Sorry guys I'm being a **** and didn't notice previous post saying this!

The latest update is sick!

Thanks man! :D

One thing, could it be possible to edit the other two gpu frequency steps? (or add more steps like on the S3? )

It could come in very handy. :)
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
Thanks man. I already gave u all the GPU voltage control the code allows. That's just the way the vdd works on crappy msm GPU chipset

I don't think it uses more than 3. It with jump from 320 to whatever you set as the highest
[Galaxy S 4 i9505 Original Android Development] iamsmallpang:
what is the default setting for GPU ?

what setting is the best VU ?

Thanks!
[Galaxy S 4 i9505 Original Android Development] nfsmw_gr:
Thanks.

The only reason I'm asking is that any time the temperature reaches around 68C the gpu mhz drop from my set max (545mhz in this case) to 320mhz (even though i've set my thermal limits way higer than 68C, 85C to be precise, btw the cpu doesn't throttle), and this drop makes MC4 for example laggy.

At 545mhz it's around 60fps most of the time, at 320mhz it's 30fps. (quite a big drop huh?)

320mhz isn't enough.

I checked this with rlorange's app.

(http://xdaforums.com/showpost.php?p=44953638&postcount=3547)

So the only two solutions would be either to control somehow the temprature threshold this happens, or to edit the middle gpu step.

EDIT:

This happens even with performance gpu governor.

EDIT 2:

I agree it's a crappy msm gpu chipset. :p

Compared to S3 it gives way less control and adaptiveness.

[Galaxy S 4 i9505 Original Android Development] kfallz:
So what's everyones results so far with UV'ing (+OCing) the GPU? Currently at 545 and 50mv UV, seems to be stable and score still increases. Simple GPU gov seems to give the best performance also!

Although antutu seems really weird.. gives lower and lower results even after increasing the voltage again or lowering the clock if it might be unstable. Letting it rest for a while doesn't help. Anyone know of a more reliable way to test it? Can't be getting too warm since rest doesn't help as already said, and not even warm to the touch. Only way to "reset" it is to reboot.

[Galaxy S 4 i9505 Original Android Development] islipfd19:
This allows the user to set a minimum frequency when audio/media audio is playing. If set correctly (to your liking) it will prevents audio stutter and skips when audio play with screen off. This also allows you to set screen off min freq to be lower than audio/media frequency.

1) Navigate to Settengs > Apps > All > Ktweaker

3) {Optional} Open any root browser, mount as r/w, then navigate to /system/app/ and delete Ktweaker apk

4) {Optional} Clear all Superuser logs

5) Reboot Recovery

6) Flash kernel

7) Wipe cache/dalvik

8) Fix permissions

9) Reboot

10) Go into Ktweaker

11) Navigate to Voltages > GPU > Menu > Load Stock Table

12) Hit Apply

13) Apply settings

15) Profit?

Check your data connection as poor reception can have a drastic affect on battery. I'd suggest turning it off when not needed and use Wifi instead. Turn down brightness to about 40% and try Greenifying some apps. I would also turn Gmail sync and location services off.

Theoretically no but TW benefits from it. Zram has been active fire TW kernels already for a while maybe you didn't notice but I've manged to make it work way better thanks to KT making it a module.

[Galaxy S 4 i9505 Original Android Development] egendomligt:
Using all default values my GPU governor is ondemand. Using this, my frequency stays at 320 Mhz when doing absolutely nothing according to the "General" screen. As soon as I start to scroll up and down the frequency drops to 200, and when I stop (still holding my finger down) it stays there, dropping to 128 every once in a while. But as soon as I lift my finger again it snaps back to 320. Is this normal behavior? Looks like inverted boosting or something o_O.

The performance governor is weird too. Using it puts my GPU frequency locked at 450 Mhz as exptected, but scrolling and animations instantly becomes unbearably laggy.. why's that?

It seems to me the "simple" governor seems to behave the most reasonable, although a bit trigger happy on the boosting (and it never goes below 320).
