NEMIX RAM DDR5 5600 192GB 6x32GB CL46 1.1V ECC RDIMM Supermicro H13SST-G memory upgrade

Exact-match upgrade for Supermicro H13SST-G

This 192GB kit delivers six 32GB DDR5 5600 RDIMMs built to the board's registered ECC specification. The 2Rx8 organisation, 1.1V operating voltage and CL46 timing match the memory controller's expectations so the full capacity is recognised at rated speed. It is intended for administrators who need a validated, single-SKU population for this specific platform.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing all six slots to remain fully populated at 5600 MT/s without downclocking. ECC corrects single-bit errors in flight, preventing silent data corruption during long compute runs or virtualization workloads. The modules operate at the standard 1.1V DDR5 voltage, so thermal output stays within the server's designed cooling envelope.

Straightforward 288-pin RDIMM installation

Each module keys into the 288-pin DDR5 RDIMM sockets exactly as the motherboard manual illustrates; no heat spreaders interfere with adjacent DIMMs or CPU coolers. The most common issue is populating slots in an order the firmware does not support, which can halt POST or limit usable capacity. Consult the H13SST-G manual for the approved population sequence before seating the six DIMMs.
