Highlighted here is what I meant. Mobos have a max amount of memory supported but looks like you are well below that, the max on this board being 192GB
I will point out that, without overclocking the maximum speed ram supported is 5600 MHz and youve picked out 5200 MHz, not sure how much of a boost it'd be but maybe look into that.
ALSO when you do get this build all set up, please please please check your BIOS and make sure that the ram you buy IS operating at the advertised MHz, sometimes they say one thing, but ship out of the box a little lower and you have to set it to the advertised speed. Frustrating to find out a year later that you've been using your system slower than it had to be.
