Socket 754 Semprons with an OPN ending in 'BX
' are 64-bit enabled. Any other OPN, regardless of the revision (ALL Sempron 64's will be revision E6), will NOT
be 64-bit enabled.
As for CPU-Z, if you're using an older version, then that will need to be fixed; if that issue hasn't been fixed yet, then they will need to recompile the program to allow the Sempron 64 to be recognized properly.

By the way, if in doubt, PM Greyhound.
