Hi Labview, I'm so glad to hear it! Thank you.
I want to ask you: how may I build a bios? cause I also have a z68 Fatal1ty Professional Gen3, that doesn't work when I activate the XMP profile and my memories are on dual channel. It only works on single channel (when I put my memos on A1 A2 slots and leave B1 B2 empty). I thought that was the max trfc value of "stock" bios (255), but I've tried with the bios that you build (to z68 of course), with a max trfc value over 500, and the issue still remains. I also found a lot of people with the same problem with AsRock motherboards with the z68 chipset and G.SKILL memories.
I've tried with two memory kits, both G.SKILL:
G.SKILL 2x 4GB 1866Mhz CL8 (model F3-14900CL8D-8GBXM)
G.SKILL 4x 8GB 2400Mhz CL10 (model F3-2400C10Q-32GTX)
If you point me the north, I'm sure that I can fix it (or try at least, to be sure that it's not a bios issue, cause if it's a hw issue there is nothing I can do).
