No, only Athlon FX 64's and Opterons require registered memory,
and that requirement for the FX 64's will go away when the 939
pin version comes out. Athlon 64's take unbuffered memory.

If you have to have dual channel ECC memory on the semi-cheap,
an ASUS SK8N nForce3 board, Opteron 14x series CPU, and as
many sticks of 1GB Corsair ECC Registered memory as you can
afford (the SK8N can take four) would be the way to go. The
2.2GHz Athlon 64 FX51 would be ideal, of course, but it's a wee
bit expensive.

Aren't the athlon64 modules required to be "registered"?
