don't really get what you wanna say... it looks like you used different versions of CPUZ, that would explain some information missing as it might not have detected it properly
for the OS reading it as a Pentium 3... Games read my processor (q9550 @ 3.85 ghz) as pentium 3 at 1.8 ghz and it still plays fine... i wouldn't really worry about it as its probably just a minor bug
