NEMIX RAM 256GB (16x16GB) DDR5-5600 ECC Registered RDIMM CL46 1.1V 1Rx8 288-Pin Kit for Supermicro H13SSH-E

Exact-Match DDR5 Kit for Supermicro H13SSH-E

This 256GB kit contains 16 registered ECC RDIMMs, each 16GB, built to the DDR5-5600 (PC5-44800) standard with CL46 timing at 1.1V. It targets administrators who must populate every slot on a Supermicro H13SSH-E motherboard and need the controller to recognise the full capacity at rated speed without manual tuning. The 1Rx8 organisation and registered buffer match the board’s electrical requirements exactly.

Replaces partial or mismatched DDR5 populations

Upgrading from a smaller kit or mixed-rank modules is worthwhile when the workload demands the full 256GB address space and the memory controller must drive all channels at 5600MT/s without downclocking. The jump pays off for virtualisation hosts, in-memory databases, or compile farms that hit capacity limits or stability errors with fewer ranks. Buyers who need a different total capacity, a UDIMM form factor, or non-ECC modules cannot use this kit.

Straightforward seated installation if population

Each 288-pin RDIMM keys into the slot one way; press evenly until the latches click. The most common error is ignoring the motherboard manual’s prescribed slot order, which causes the system to train at a lower speed or to report less memory than installed. Verify the approved population sequence before seating all 16 modules, and confirm the BIOS sees 256GB at DDR5-5600 before returning the server to production.
