I am a behind on work and need to work through the weekend so I will not be looking at this again until Sunday evening. If
@Leesureone wants to step in and take over until then, please do, I welcome your help and input.
I suspect that all of this BIOS patching by OC and Clover may corrupted the NVRAM. I personally have not had any issues but would suggest that you save your BIOS profile using the tools menu in BIOS and then update to the latest version of BIOS. Reset your CMOS by shorting the proper pins (look in manual, When the machine reboots, restore your profile and you should be good to go.
I personally have not had this problem so I am have no other advice than what I just posted. I will be back Sunday with have some updated EFIs for both OC and Clover that I will roll out then.
I wanted to spend some time debugging for you so if you can keep an eye out on Sunday, I will work to resolve your issue as best I can.
