Imo it is stable now. Gpu stays at 490-525 most of the time. On heavier loads it starts to use 920. No artifacts. Drainage is more optimized compared to stock RA fork. In the video you can see with adreno boost set to low it uses 920mhz, then i disable it and it stays on 490. See the mA drain differences. Normally 920mhz comes with max voltage level, i dropped it 2 levels, got artifacts and bumped up 1 more. Basically it is 1 step lower than stock RA fork. Well many of the clock voltages are 2 or 3 steps lower.
