Guys: Windows XP x64 just came in the mail from MSDN today. So let's see what this baby can do.
Everything looked fine.... until.... I installed the nForce drivers for my nForce 3 250 GB chipset. My PiFast/SuperPi times just doubled... I went from 60 secs pifast to 120 secs pifast (stock speeds for compare).
I reinstalled Windows XP x64, Pifast dropped to 60 again.
I also checked on my nForce 3 Ultra system and had the exact same problem.
I'm using newest nVidia 64-bit drivers from their website.
Anybody else seen this problem? Anybody know how to fix it?
When I don't install my nForce drivers my sound doesn't work so that isn't an option. I tried installing only the sound but the very minimum nForce installation f uckes up the CPU performance (memory bandwidth in Sandra is fine)
Very strange deal this is.
