I have the MSI mobo too and no, it was NOT set to clear CMOS when I got it. I've had no problems with the mobo whatsoever I might add. The only complaint I have is, I tried setting FSB to 120 and the computer wouldn't post, and having it turned off for a few minutes didn't help either. You have to clear the CMOS to get it back online - on that point, ABIT's boards are cooler.
