GiganticDays, whomever they are from, Athlon boards in general and those with integrated graphics in particular want RAM that is absolutely, 100 percent, OK. Given the struggle DRAM makers are currently in, guess what went down the drain first in their cost cutting ... yes right, QA.
Out of every three DIMMs I buy, at least one is bad.
www.memtest86.com is your friend. I even doubted the mainboard once (yes it was a PC-Chips), but with the fourth DIMM it actually worked fine then (and still does). This is not going to become any better when you use DFI instead ...
