Mine is set at 1025v and is ate SOC speeds and plays quite nicely
I was getting a few artifacts in occt in 2d mode but in 3d mode it was perfect with no artifacts
I have no problem in heaven benchmark and games, No artifacting
Also OCCT gpu mem test shows no errors
i agree with you thats a stupidly low v on the gpu as i have to increse the v's on my sparkle 480 to 1100v to hit 850 core so was and but when i see this SOC core v's
Have you actually ticked the check for errors checkbox to see if it detects any GPU errors? Or are you just watching closely for artifacts?
