has any one of you tried hard restting your boards bios?
1- power down pc..
2- remove all power cables connected internally and externally...
3- after "1 & 2" remove CMOS bat..for 20min...walk away..take a swim or beer break..also remove all ram sticks..
4- after #1/2/3...re-insert cmos bat..reconnect all power cables..intarnal and external...plus anything you unplugged..
5- power/boot up pc..wait till bios set up prompt comes up..go into bios..load defaults../AUTO for everything possible....leave it all stock..
OH PS..also disconnect your hds...when disconnecting the power etc..just to prevent any issues with data loss etc etc...
6- after load defaults..makes sure it boots all the way to windows...run your usual/preferred array fo tests..prime small fft etc etc etc......for say atleast 1-6hours..if stable...proceed to start your tweaking.....
ram- use auto for everything and XMP on..if this fails..then use previously mentioned method of manual tweaking
