Question Asus rampage formula stuck on DET DRAM and CHECK CPU

[leo.kerr300]

So my board appears to be stuck on the following stages. DET DRAM and CHECK CPU. The ram and cpu works as i've got it into a optiplex and it booted. I think one of the dimm channels may be broken(DIMM_B1) but does it matter since i've only got 1 ram chip in DIMM_A1?

full system spec?
