I currently am upgrading from an athlon fx-55 system a couple years old to an e8400/msi p6n diamond/supertalent pc2-6400 mem system...SO far after all the research and finding the best pricing possible I can play in the bios and watch the picture of a diamond come up in the boot screen and everything right up till windows SHOULD start and show it's loading screen. At this point, it just decides to reboot...and continue an infinite circle if I so chose to spend the rest of my life having so much fun. At any rate, everything I read said dual core 45 nm cpus WOULD be 680i compatible, but not 45nm quad...and so far the msi website shows one of the 45 duo's compatible the rest are still testing. So, now that evga has released a fix for compatibility with 680i/45 nm duo's...I have NO answers as to if my setup is compatible OR will be. Unfortunately after scouring the internet I see nothing online addressing this whatsoever...so yes I'm rather frustrated and this completely sucks to say the least. However the other crinkle is I have windows xp which was acting up recently and I in a move to a new house lost the disk, so it's possible windows itself is the real issue and it just is more pronounced on the new setup. Because the bios DOES recognize the e8400, lists it's speed, front side bus etc etc...so it seems it should work for most cpu/motherboard incompatibility issues I've read about talk about how the bios won't even run or it does but won't list the processor correctly or at all... One word...HELP!!!!
