From the book code 15 means early NB initialization. I tried "cure" the problem with more voltage (VTT, VCH, etc to 1.3) but it doesn't seem to help. The memory is on default.
From quick search the code 15 is supposed to be related to cold boot problem? So any suggestions or I just fried my CPU?
Is it safe to downgrade the UEFFI to previous version where it was working?

EDIT:
I am back to version 1.42L and crunching at 4.7@1.39. The newest UEFI obviously didn't work for me, but I am not as extreme as you guys to need it at first place


it looks like u are failed on bios updating to 1.6

U can try to update again by the bios jumper close by the bios rom .
