Could it be my card hates juice and runs better on lower volts it made it thru the sniper v2 benchmark at 1200 on stock volts where it would normaly crash or artifact.

Higher ASIC quality means higher overclock with less voltage.

That's rubbish. ASIC has no bearing on overclock.

Of the 30+ cards I've binned this year the higher ASIC ones did, in fact, overclock better with less voltage. /shrug

If that were remotely true, then what... all the 80%+ cards would achieve what overclock and the 75% and less are incapable of... what overclock?


It's rubbish. I've been thru over a dozen and I only had one 80%+ card that went over 1300. The legend doesn't hold... it's random.

based on my tests tonight my card tops out at 1160 game stable it runs 1150@1.18 and 1160@1.20 but nothing higher is stable no mattter the voltage lol least the memory clocks high that gives me a couple fps boost.
