Ok, so I bought 2 5830's and have them crossfired on my main PC, and I bought a 5850 because the 5830s were sold out, and I put that alone on another PC. All are XFX brand.

So I am able to clock my 5830's to 1010 mhz and get about 300 mh/s, but when I tried overclocking my 5850, I could only get it up to 900 mhz and it kept crashing the computer and blue screening it. Then I started getting hard core artifacts, and finally it just died. I can no longer boot that computer, nothing is coming up on the screen.

After only 1 day, the 5850 is dead and I don't know why. The temps never got above 70* C.

I used ATI Tray tools to up the voltage , and TRIXX to up the clock rate.

Am I screwed? What's the deal with 5850s? I was getting 350 mh/s before it died on me, and it would be nice to have that again... Anything I can do?

That is probably why. Also Xfx cards are not the best for overclocking.
