I even disassembled my build and unplugged all SATA cables, removed two sticks of RAM and GPU and tried two different 8GB and 32GB drives to no avail. I had an old 4GB drive laying around and when plugged it in Windows, I found out that I had already copied modded X99-A BIOS on it two months ago. How could I have forgotten that!You need different pendrive.
Do you have 16GB one (or less) ?
(micro)SD card with card reader will work too.

I first tried -0.09V undervolt on 103 MHz BCLK, but Windows bluescreened when I was unzipping Cinebench R15. I then applied -0.05V undervolt. The CPU frequency is 3500MHz when idle, 3400 MHz when running Cinebench R15. However, the frequency is barely 3 GHz when running Cinebench R20. I tried 105 MHz BCLK, the system seems to boot, but there is no video signal and the screen just remains black.
Behold my Cinebench R15 score.
