My bad, what i've meant was "oc mpu with stock dsp clocks" is not stable, stupid sentence composition by me

I'm aware, thats why i mentioned about 720p video playback issue, because it creates a 60+% mpu load + dsp load. only done for testing purposes and curiosity.

Same modified dsp profile was used was all tests (only the dsp frequencies were changes as mentioned on previous post)

Yes, it seems to be stable.

Custom profile :

up to 600 SR calculated values are fine, though I'm used to supplying a lil more voltage( about 1-2 steps additionally against the SR calculated (real) voltage)

@ OC freqs,

720 45 430 (caused reboot at 43 [= SR calculated voltage])
805 50 430 (causes reboot at 48)
850 52 600 (-used mainly for video recording purposes)
900 54 600 (-used mainly for video recording purposes)

DSP profile (SR) - with flat dsp rate of 430

pls note that the values are as shown on kernel config

250 23 180 - stable
500 36 360 - stable
550 38 400 - stable
600 40 430 - stable
720 45 430 - not stable
805 49 430 - not stable
850 51 430 - not stable
900 xx 430 - reboot withing 2 seconds

*ps : above result are done without touching dsp boost value.
