Server memory upgrade for Supermicro H13DSH

This 384GB kit delivers eight 48GB DDR5 registered ECC modules built to the exact rank, voltage and timing the H13DSH memory controller expects. It is intended for administrators expanding a single compatible server to its full supported capacity.

Registered ECC RDIMM form factor

The 288-pin RDIMM registered architecture is the single specification that determines fitment; the board requires registered modules and will not accept unbuffered UDIMMs or SODIMMs. ECC corrects single-bit errors on the fly while the registered buffer lets every slot run fully populated at the rated 6400 MT/s speed.

384GB total capacity across eight slots

Eight 48GB dual-rank modules fill all available DIMM sockets on the H13DSH, providing maximum memory headroom for virtualisation, large databases and compute workloads. Capacity runs out when the platform's slot limit or per-socket maximum is reached, so further expansion requires a different server chassis.

Questions about this item

Will the 6400 MHz speed run at that rate on my Supermicro H13DSH?

The kit is rated DDR5 6400 (PC5-51200) and is verified for the Supermicro H13DSH motherboard. The board's memory controller must support that data rate for the modules to operate at the advertised speed.

Does the 288-pin RDIMM form factor match the slots on the H13DSH?

Yes. The kit uses the 288-pin Registered DIMM (RDIMM) form factor that the H13DSH requires. It is not a UDIMM or SODIMM, so it fits the server's DIMM slots mechanically and electrically.

What physical clearance do the modules need since they lack a heat spreader?

The modules have no heat spreader, so they occupy only the standard RDIMM height. Ensure the server chassis and CPU cooler allow the normal DIMM profile; no extra vertical clearance is required beyond the bare PCB.
