Finally got it stable at 575FSB 1:1 on F6a
What you put in the bios IS NOT what comes out in Windows!
I will put up my bios settings tomorrow to show you guys how the figures translated for me.
Just received my brothers upgrade parts:
Gigabyte EP45T-Extreme
Intel E8500
OCZ 2GB (2 x 1024mb) DDR3 2000 Platinum Enhanced Bandwidth Edition PC16000
Start on that one tomorrow
