Phenom seems to have a lot of problems with everything especially that level 3 cache bug. I'm really starting to hate AMD for all this cr** they are doing.
I believe that a later bios should adress your ram issue. I have an ASUS M2N-E that had one hundred problems in the beginning, and they were all fixed with some 5 or 6 bios flashes. Waiting is the best thing for you to do right now.
