Overclocking 7970WF OC

[masscrazy]

I cant really get a stable overclock and cant really tell when it is stable.

Stress tests kombustor, furmark all run fine but in game things get weird. Mostly the driver crashes and doesnt fully recover and leaves windows hanging.

I've tried 1140 1181v 1425memory. Not stable, temps dont go over 75C. While playing bf3 temps were around 69 and it crashed.

Any advice?

1187mV 1155/1510 = 100% fan speed with temps of 80 and rising.

I thought it would have performed much better.

Hmm so the stress test shows no problem whereas when you actually play a game there are stability issues:
Either you havent stressed the card enough giving you the impression that its stable until you actually try a game and it crashes or there is a problem with the drivers with this specific game. Do you experience the same at stock clocks? Have you tried the overclocked settings on a different game and is also unstable?
From what i ve been reading you should be able to hit 1050-1100 without additional voltage and around 1250mv when getting close to 1200mhz. Atleast thats what other people are getting if am not mistaken. There is also the issue of luck here...

1181mv 1130/1510 - runs really hot and loud (100% fan speed) but its stable.

Its actually made my room hot, the air thats being pumped out is crazy.

TBH i've stressed it for long. But i think i'll keep these for now.

at 1140/1415 i get a 3dmark score of p8673 gpu score of 9246. At 1130 its probably 9100.

How is 9100 gpu score in 3dmark 11?
