Hi.
I've got a problem. Ive got 2x5870. Both running 955/320. The first one is stable as hell (Runs like for 2 weeks with no crash) but second card is crashing like every 5h. I tried lower clocks, but no difference. IT works perfectly in games etc. (No crossfirex, 11.6 SDK2.4)
when I have those issues, I usually just rerun 11-6_vista64_win7_64_dd_ccc_ocl. I run my 5870's at 950/440 I think they run a little better with a little more memory(more stable) mid 70's temps
