What Mem are you using this board is very prickly about what ram is used because of what the BIOS looks for at Boot. IT HAS to be DDR3-1333-10600 it can not be DDR3133310666 it will not work without changing timings in BIOS. The extra 66Mhz Throughs OFF the BIOS .
OCZ OCZ3P13334GK PC3-1066 DDR3 1333MHz Platinum Series 4 GB Kit
look for it on google, that is the model of memory I have
I guess it has the 66 more that you tell me OFFs the BIOS.
Is there a workaround for this problem?
Replace it with the correct RAM . DDR3-1333-10600. Or write a new BIOS.
