Overclocking sapphire hd 6870 problems

post #1 of 3
Thread Starter 
I have a i7 950 OC @ 3.9 and a Sapphire Radeon HD 6870 that I would like to over clock as well. Whenever I raise the clock speed of the core and the memory higher than the defaults and try to play Battlefield BC2 the screen freezes after playing for about 3 min. I am using the ATI overdrive with aprox. 950 core and 1110 mem. Well under what that card can do stable. Any ideas?

you can use MSI afterburner then run some benchmarks or see if its stable or not plus you need more voltage on that overclock.

Overclock the core & memory separately so that you know which one causes the instability.
