What Rev board do you have, just i looked at your screenies and it shows yu using F2 Bios. Now:
Rev1.0 Board latest Bios is: F6
Rev2.0 Board Latest Bios Is; FB
And, on the Gigabyte website, F2 Isn't ven available anymore. I'd suggest updating your Bios maybe.
Improve Recovery software compatibility
Intel 22nm CPU support update
Improve OCZ PCIe SSD compatibility
Support GIGABYTE TouchBIOS
Support Intel 22nm CPU
Support GIGABYTE TouchBIOS
Support Intel Smart Response
(Note: Please install the latest IRST version: 10.5.0.1027 or above)
There the main changes in the Rev1.0 board from F3 TO F6.
Just a thought
Edit: I have th rev1.0 of this board, might try the setting posted above. (Should i touch the advanced memory settings, i have 2x4GB Corsair XMS3 1600Mhz)
