I've found it frequently helps to manually set the VDimm to the rated voltage for your memory...probably 1.35V, but check it's package.
Also, if you've ever used any other memory or this is a 'first boot' after a build do a CMOS reset first. If you're unsure of this just do a CMOS reset anyway.
And last...probably obvious...make sure the DIMM's are in the 2nd and 4th DIMM sockets going away from the CPU.
