So I had a serious issue with my Vista 32 bit build over the weekend that I gave up on and reformatted back to a custom build of XP 32 bit. I used it for about all of Saturday no issues. I installed Vista Ultimate 64 bit and I'm seeing a lot of weird CPU activity and CPU-Z is reporting a clock of 1.5ghz instead of 2.4ghz stock. I set the bios to fail safe settings. The clock will read 2.4 initially then underclock its self to around 1.5ghz. I tried to use the Gigabyte easy tune app to get the clock to normal with no avail. Is it possible that there is a power saving utility running through the BIOS?. This is my first 64 bit install and I've never seen this issue before. Also could it be that my cpu is getting less power now? Should I be running the 8pin connection instead of 4? I had very little time to troubleshoot this issue last night due to exhaustion and I was just really sick of playing with the damn thing. Thank you in advance to anyone who can help.
