MEMORY (yeesh)

Samsung 32GB DDR5 4800MHz PC5-38400 ECC RDIMM 2Rx8 Dual Rank 1.1V Registered DIMM 288-Pin Server RAM Memory M321R4GA3BB0-CQK at Amazon.com

COOLING

That RAM looks wrong, since when does it support U-DIMMs?
That cooler also isn’t the Threadripper version.

Does that board support any bifurcation other than x4x4x4x4?
