It should not require a reinstall. It may ask you to verify the settings in bios, but Windows should still work properly.

I've gone from AMD64 3000+ to my Opty 165 & back multiple times without having to reinstall. You will, however, have to apply the dual-core hotfix and configure it to your OS when you make the change.

OMG Im about to go crazy, lol. If he has SP2 he DOESNT need any of the Dual Core Patches, maybe with SP1, maybe. But even then if he has Automatic Updates turned on he still prob doesnt need that, why is everyone thinking you need these patches, theses patches were utilized mostly when the DCs came out last year. Sorry to rant a little, but this is like the 3rd time today people have recommended them.

No. Don't reinstall.

Do this:
1- uninstall driver for CPU (in hardware manager)
2- reboot. It will detect new hardware...let it install the new drivers (multi CPU)
3- download amd dual core driver, and all those other dual core things from AMD 's official website.
4- download microsoft dual core hotfix.

that's basically it.

Wrong. It's not dependant on having SP1 vs. SP2. It was never written into SP2's code either. I know this from experience, as I had to apply the hotfix to my own install of SP2. Don't know where you get your information, but you should do a little more research.
