System overall works fine but having issues "enabling" XMP profile or any XMP profile for that matter. after XMP is enabled system will not boot, not sure whats going on or where to go from there? Also unable to overclock my CPU. Bump up the cpu to 4.3 on 1.3volts and unable to boot. Unable to do any overclocking. not sure if its the board or some setting im missing in the BIOS/UEFI BIOS ANY HELP is great
