Early OC'ing wall with ASUS HD6850?

post #1 of 2
Thread Starter 
I recently got a DirectCU HD6850 and was pretty eager to OC it. These are my results so far.

In order from top-to-bottom; Stock, 825/1025, 850/1050, 850/1075. These graphs are a 5minute run in Furmark, 1280x1024, no AA.







Problem: Increasing the core any further results in a crash (tested 860/1075, crashes within 2 minutes. computer restarts).

CPU: Phenom II x3-720 unlocked to Phenom II x4-920 OC'd to Phenom II x4-950 (3.1ghz).
PSU: CoolMax 600W, +12v1 @ 18a, +12v2 @ 18a, +12v3 @ 15a. Combined wattage of 450W.
GPU:

*Ed
And yes I know I'm aggressive with temperatures, but I don't hear it over my case fans, and I like to keep my card cool. I'll freak if it hits 75c.

Increase your Vcore to 1.2V and you should be able to reach 930mhz on the core (a 20% increase over reference clock, you should be more or less satisfied) with furmark stable. But the temperature could reach 85C in Furmark's extreme burning mode (28C ambient), which is acceptable to me.
If you want more FPS for playing games only, you could increase Vcore all the way to 1.3V and overclock to 1Ghz on the core, but its not Furmark stable, and occasionally could crash intensive games like crysis
