NEMIX RAM DDR5 4800 128GB 2x64GB CL40 1.1V ECC RDIMM memory upgrade for Supermicro H13SST-G

Exact-match DDR5 ECC RDIMM kit for Supermicro

This 128 GB kit delivers two 64 GB DDR5-4800 modules built to the precise rank, voltage and timing the server's memory controller expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. The 288-pin RDIMM form factor matches the motherboard's required slot type exactly.

Registered buffering and 2Rx4 layout for full-slot

Registered buffering offloads the memory controller so all channels operate reliably at maximum capacity without signal degradation. The 2Rx4 organisation aligns with the board's population rules for dense configurations. Modules operate at 1.10 V standard DDR5 voltage and carry no heat spreader, fitting tight server DIMM spacing without clearance issues.

Low-voltage DDR5 operation reduces thermal load

Running at 1.10 V keeps power draw per module low, easing cooling demands in densely packed chassis. CL40 latency at 4800 MT/s provides predictable timing for latency-sensitive workloads. ECC correction prevents silent data corruption that would otherwise trigger unplanned reboots during production runs.
