3D01 is ultra tweakable, in this case make sure the CL is high enough. You can adjust nature later on till you get close to 999.9
Try to get the ram as tight as possible ( via memtweakit ) 3D01 is very sensitive to it. Don't even think of running single channel... I would carefully remove the heatspreader of the dimms...
Also is the legacy benchmark setting enabled in the ASUS bios ?
