My Friend had this setup a few days ago:
A8N-SLI Deluxe
AMD 3500+
4x Corsair 512MB XLPT (2x matched pairs)
Working fine @ 333FSB (wouldnt run at 400 - something to do with the memory controller in the cpu if i remember correctly?)
Bought X2 4200+, blue orb 2, artic silver 5 as a tempory upgrade (new system build later on) and it failed to boot.
First he thought it was the cpu and reseated it. It booted up and he went into the bios to check things and exited without saving changes (no changes made). It then failed to boot, fans spinning, no bios, no beeps etc.
A few more reseats later and he finally thought maybe its not the cpu - plugged in his speakers and got the 'system failed memory test' sound error.
He is currently running his memory in single channel mode using 2 slots, he went throught the 2nd slot with the 3 remaining memory modules and only one made the pc fail to boot.
Logic suggests this module is faulty, but in the past he has randomly had 'system failed memory test' one or two times before on this motherboard with his old 3500, reseating (mixing up the slots) usually fixed it.
Why is this board so problematic with memory? Any suggestions?
