I'm running Bios version "0602".... I flashed it right away, without testing the version that came intalled on the board.

I've actually had pretty good luck with it. I've got 3.2/2.77 stable on XP64 with reasonable V's (1.4/1.3), I don't run X-Fire or anything though.

I have a question for you folks who have had the board longer.

Any opinions on the best OC BIOS for a 1 card 4850 with 4Gb of ram and 64bit OS?

Since Chicken Patty seems to prefer "0403" I'll probably go ahead and try it tonight, seems like he's had the board longer than most...

You've also had pretty good results man, so I respect your opinions.
