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! BIOS FlashBack was now successful on my X99 Deluxe II.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. It is even higher than it was on X99-A on the BIOS same settings.
Now where is bobbybluz with his promised E5-2699V4 score?
