I restart my s3, then test the two benchmark a first time with mali status to see if it goes at 600 and then without mali status.

edit : don't know if it is mali status or stweaks/kernel problem,
but mali status shows me at reboot 160mhz whereas my minimum is 2** in stweaks
and now, after try nenamark a first time, it keeps showing 440mhz while im not using any special apps, the gpu usage under 5% and therefore it should have a lower frequencie

Can u give a link to download the mali gpu status app please ? Have found the app with Google after searching 10mn and maybe have a problem...

I posted it once in siyah thread, can you search there? I'll add it here soon

Don't forget running it or any other overlay app will reduce your benchmark scores

It's a little low... ?

new test
change the threshold frequencies to (DOWN UP) 70 - 60 85 - 85 80 - 90 80 - 95

I restart my s3, then test the two benchmark,
a first time with mali status to see if it goes at 600,
and then without mali status, for real tests.

Re-install mali gpu status. Still have this problems ... :/
Will try again after Omegav12 update and reinstall the kernel

Question gpu OC

@ OP
under ninphetamine kernel, OC'd gpu through init.d script, with appropriate permissions set, to echo OC values for the gpu
Code:
/system/xbin/echo "266 350 440 533" > /sys/class/misc/gpu_clock_control/gpu_control;
/system/xbin/echo "875000 900000 950000 1000000" > /sys/class/misc/gpu_voltage_control/gpu_control;
seems to work. noticed on your sig though that you have 5 values for gpu OC (which i copied up to 533, btw). what effect does the following lines in red below have on cases such as yours i.e., >4 values? i'm sure ninphetamine supports >4
Code:
Step0: 266
Step1: 350
Step2: 440
Step3: 533
Threshold0-1/up-down: 27% 24%
Threshold1-2/up-down: 35% 33%
Threshold2-3/up-down: 35% 35%
does one need to edit them or add lines accordingly? i'd like to understand first before i blindly go testing stuff. tia!

THe 5th stepping is added by @gokhanmoral in the latest beta of siyah kernel, so double check the ninpho kernel thread for the 5th stepping support.


The threshold value determines at which load the gpu should change the steppings. If the load of a stepping goes beyond certain limit or percent(eg threshold 1 up) it will switch to 2nd stepping.

hi .. i havent seen any significant drain in battery with daily usage as my max voltage is still within stock value but yeah there might be few drain due to higher clocks but that would be negligible

ok, fair enough. mind sharing your complete output of cat /sys/class/misc/gpu_clock_control/gpu_control?

Step4: 600

I would suggest you not to change the thresholds.
