Kingston Server Premier DDR5-4800 ECC RDIMM 1x64GB

Server Premier is Kingston's branding for the DDR5 memory it validates against specific server platforms rather than selling as a generic desktop part, and the RDIMM version here routes command and address lines through an onboard register the way DDR4 RDIMMs did, though DDR5 moves more of that buffering onto the module itself.

This one is 1×64GB, 64GB, rated 4800 MT/s CL40. Server boards typically validate memory against a qualified vendor list rather than accepting anything that fits the socket, so confirming this specific speed and capacity against the board's own list is worth doing before ordering.

Every module in this family is ECC, correcting single-bit errors in hardware — standard behaviour for a line built around server reliability rather than desktop use.
