I only have an 1800X for AMD systems, I mostly run Intel, but I had a lot of blue screen ram issues when my voltage in the bios wasn't set exactly at the XMP voltage called for. It called for 1.35 I think and I had it at 1.355 and it was blue screening. I can't see how 5 mv was causing BSOD but I'd verify all the timing and voltage matches the RAM specs.
