Thank you for your reply!
I know i used your guide since i had the CPU but had to go with the Gaming 3 because the 7 wasn't avaliable.
I basically adapted your BIOS settings but i selected an XMP profile for my RAM could this be the problem?
I changed the frequency back to 1333 MHz yesterday...
I've built an Hackintosh for my mum and everything works perfectly fine!
Except for the fact that sometimes the screen freezes for ca. 5 sec and then the BIOS screen appears and he restarts.
From what i can understand in the error report it's a kernel panic.
Bootloader: Clover 2.3...
