NEMIX RAM 128GB (2×64GB) DDR5-4800 ECC RDIMM CL40 1.1V 2Rx4 Supermicro H13SSW

128GB DDR5-4800 ECC RDIMM kit for Supermicro H13SSW

This 128GB kit contains two 64GB DDR5-4800 registered ECC modules built to the 288-pin RDIMM form factor. It targets administrators upgrading a Supermicro H13SSW motherboard where full-capacity population and error correction are required. The 2Rx4 organisation and 1.10V operating voltage match the board's native memory controller expectations.

Verify DIMM population rules

Before ordering, consult the Supermicro H13SSW documentation for approved DIMM population order, supported capacities per channel, and any BIOS version requirements. The kit uses registered RDIMM modules, which are not interchangeable with unbuffered UDIMM or SODIMM types. Confirm that the board accepts 2Rx4 registered ECC at the rated speed.

Registered ECC architecture maintains stability

The registered buffer reduces electrical load on the memory controller, allowing all slots to remain populated at 128GB without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during sustained server workloads. CL40 latency and 1.10V operation keep timing consistent across extended duty cycles.
