hi,

I got about the same issue with G.Skill F3-17000CL11Q-16GBXL memory..............G.Skill F3-17000CL11Q-16GBXL memory modules at 2133 Mhz ( or higher ??) - GSKILL TECH FORUM
Last saturday i updated my bios to "beta bios L2.01 8/23/2012 Support Windows 8" and booted 2133 mhz memory,mainly basic bios settings without any problem
ASRock > Products > Z77 Extreme4

So diggles maybe you can try and flash your mobo to L2.01 and see if that helps you....if not reflash to 2.00 , no harm done
If it helps 'ill be glad to hear it.
