Motherboard is flashed to 2.80, memory is loaded in slots 1 & 3 and whether I set XMP to profile 1 or 2 the memory is clocked to 2133 and boots fine but during OCCT/Prime 95 testing it fails within the first couple of minutes at stock CPU speeds. Once I switch the mem to AUTO its then clocked at 1600 and the system becomes stable.

I can overclock the CPU to 4.5 and its still stable passing all tests however as soon as I enabled XMP again to 2133 the system loses stability and . Any suggestions?

Thanks in advance!

You sir are a genius! Boosted it to 1.13 and it works like a charm now and was able to pass stress testing!

Many thanks again!
