I'd try manually setting the RAM settings in the BIOS. Also check to see what BIOS version you have and what the latest BIOS version is. You may need to update for the mobo to work with the specific RAM you have. It would also be worth e-mailing Asus and G.Skill to confirm that the specific RAM that you have will work with your mobo. Did you buy the two DIMMs as a Matched Set or as individual DIMMs? Some times individual DIMMs will not work and a Matched Set is required.
