question about cpu and memory for athlon64.

[Gulzakar]

quick question:

I know the FX series processors require registered memory...I know the Athlon64 4000 (939) can take regular DDR.

Can i use registered memory with an athlon64 4000+ ?

No... socket 940 processors (including the Athlon 64 FX for skt940) require registered memory while socket 939 processors don't support registered memory.

CDGNR hit the nail on the head but I'll use a few links to back up the argument.
