Sapphire R9 270x max voltage

post #1 of 2
Thread Starter 
Anyone know what the max/ safest voltage these cards can handle with water cooling? Right now I have it set in Overdrive at the 50% power level, and my temps don't go over 55c with full load running for an hour.

edit - right now the voltage showing in gpuz is 1.263 via Overdrive @ 50% power level.

Whoa. My 270X cooks mining X11 at 1.225. I wouldn't go over 1.250 with mine, but for yours, I would say 1.3v MAX - and of course, watch temps.
