Yeah, I was surprised that it didn't work either. The BIOS real-time OS adjust was actually OFF using default settings. After I enabled it I saw the core frequency drop to 1.2 GHz, but then got stuck there even when running prime95.

Bottom line. Nobody in their right mind would be running XP 32-bit paired with a 3960x. Only a fool like me because that's the only OS I had availabe when first putting it together. Now with Windows 7 everything is running very smoothly.

Thanks for all the feedback.
