I've got Windows XP Pro SP2 (32bit) running on a Foxconn NFPIK8AA-8EKRS (nForce4 Pro AMD) motherboard with an Opteron 252 processor.
I'm not certain how Windows detects the capabilities of a processor (SSE, SSE2, SSE3, PowerNow!, etc... etc...), but Windows XP is reporting the processor as "AMD Processor Model Unknown."
What's strange is that none of the drivers or the OS seems to have an update for this CPU.
I originally installed the OS with an Opteron 848 processor, and then plopped in the 252 as it's a little fast and supports SSE3. (This is the game box.)
Does anyone know how to remedy this bizzare issue?
(I did install some stuff from AMD, updated platform drivers from nVidia, and got all of the current WinXP updates.)
