I have the same problem and the same board. I have 2 of those boards and it doesn't happen on one of them.
Another really annoying thing is that it gets lots of incorrect shares, I assume because of this, because there are no memory errors in any of my cards.
The White USB ports also DO NOT WORK. That is in BOTH motherboards. Biostar really needs to get their stuff together. BIOS updates are poor too. I'm not buying this again, I'll go for ASRock next time.
