Solution
With Gigabyte mobos, ACC (Advanced Clock Calibration ) can be accessed under the "MB Intelligent Tweaker" (M.I.T) option in BIOS.

If you can't find ACC, then press 'Control + F1' keys on the MAIN Page after entering BIOS, the screen will flash, then go into the various sections to look for hidden settings. However, this trick may only work on certain Gigabyte BIOS version like the F2D BIOS.
