YES Latest bios.
I thought this would be a simple swap but noooo. Maximus x hero with latest bios that worked perfect before the switch to the 9900k. Now any time i try to use xmp i get constant random freezes,crashes and errors with bsod. I ran the built in memory test in windows and got errors but i cant believe it worked fine yesterday and now it wont. Without xmp it passes the memory test in ixtu and no problems. Anybody have any ideas on this? I did take the memory sticks out and reinstall them just to make sure.
I havent touched the cpu yet its at stock settings.
