To provide clarity: If set to XMP, the system can't even get back into UEFI. (power cycle 3 times then locks up on logo screen)
If I set it to CL7 manually, regardless of memory speed; the same thing happens.
If I try to use OC Genie; the same thing happens.
Aside from that: These boards only have 16GB max memory limit too compared to ASUS' 32GB.
Did another 2 hour memtest at the settings listed in my previous post; no problems again.
In a completely unrelated issue: My keyboard randomly stops working in a certain game. I haven't tried different USB ports yet, but this did not happen on my old motherboard.
Yet another problem. /sigh
Also; what exactly is the "power cycle" issue? I find my system randomly turning on when I didn't even hit the power button, though this is only after I turn it off with the power button. It also delays power on and power off in certain scenarios.
