HD 5870 Trouble with overclock.
May 8, 2010, 9:01 PM
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?

What are software are you using to overclock the card and what speeds are you attempting?

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.

Doesn't matter what clock i try.
I have tried with 875/890/900 on core with stock voltages, ever crash.

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)
