Right. Got everything working now. Made all the changes you specified, except FSB = 1267 and Mem = 800. Everything was set to what you specified. For some reason, my system is unstable (won't even POST sometimes) when I set FSB to 1333 for 3GHz. Any reason why this would be?
Have you installed 1303 BIOS?
