Cold_Fire
Does it do this with the bios set to defaults?
Q-Code AO is a good code once handed of and booted into the OS, but you say you have AO and stuck on the ROG logo, I have never seen this, but suspect it is memory related
My MVIII Formula came with bios 1601, I have a set of Corsair LED Vengence 3466 mhz 4x8gb kit, bios 1601 is the only bios that can run XMP with any stability, if you have not read the Skylake OC guide I would suggest you read that first
I would increase the dram voltage,vccio and vcsa voltages by a couple hundreds of a volt
When I set XMP in the bios it gives an option for enhanced timings, if you have the same option click NO for better stability
