Hmm, after looking around a bit I see there are both an XP120 and an SI120, SI being newer
For the SI's description it says this:
AMD: Athlon64 FX 3200+ (socket 939/940) /Athlon64 3200+ (socket 754) and above
So, for Athlon 64 3200+'s and above it will work, but it says for s754
After reading that, do I need the XP version?
