I have one HD 5870 850/1200 and i'm trying to overclock.

I can overclock memory clocks without problem (1290), everything runs fine, but when i try overclock core (850+) speed doesn't matter what game i play, system crash.

Windows says the driver stoped work.


Anyone can help me?



System Specs: Asus PT6D Delux, I7 920 @ 3.8, HD 5870, PSU Corsair HX 1000w, 3x 2gb Corsair XMS @ 1600.

Thanks and sorry bad english.

Are you overvolting because extra voltage is required to reach higher clocks.

I believe they tend to get up to 900-950mhz just on stock voltage though.

you may simply have a card with no OC headroom. unfortunately they do exist.

what temps are you hitting when you overclock? (download GPUz to log them)
