No kidding. I just had two days of messing around with and older, AM2, build with a Biostank mobo. Couldn't get the damn thing to post after taking out a harddrive to use elsewhere. I kept getting a memory error beep code. Finally noticed that the memory had a lot of play in it when it was seated, it would easily wiggle back and forth. I got it centered in the slots as best as I could, hit the power, and voila! It is working now, but it doesn't exactly inspire a lot of confidence in the quality of their manufacturing.
