im going to guess that it's x64 WinXP... may not be a Dual Core or something within that problem range. Contact nVidia and AMD! you'll get great help from the source!

Oh! Try looking in the BIOS Menu! options are available for processor speeds like Hyper-Threading (x86\P4-HT)

how do you know its regocnizing it as a single core? did you check in the device manager to see if it shows one core or two? is the correct XP version installed (xp 64bit or 32bit)?
start menu%26gt; control panel%26gt; system%26gt; somewhere here got a setting for duo core processing.

just presuming!!!

I belive you should download and install this update from AMD http://www.amd.com/us-en/assets/content_...

Most often AMD needs a driver to modify the OS for performance. And its still the best CPU

There are some other good update you can download for your system from http://www.amd.com/gb-uk/Processors/Tech...
