NEMIX RAM DDR5 4800 CL40 288GB (6×48GB) ECC Registered RDIMM for Supermicro H13SST-GC

Exact-Match DDR5 Kit for Supermicro H13SST-GC

This 288GB kit contains six 48GB DDR5 4800 RDIMMs built to the precise rank, voltage and timing the Supermicro H13SST-GC memory controller expects. Registered ECC architecture with CL40 latency and 1.1V operation ensures the modules are recognised at full capacity and run at their rated PC5-38400 speed. It is intended for administrators upgrading or populating this specific server platform with validated enterprise memory.

Registered ECC Design Frees the Memory Controller

The 2Rx8 registered modules buffer address and command signals so the controller can drive all six slots fully populated without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. No heat spreaders are fitted, so airflow must be managed by the server chassis. Installation must follow the motherboard manual’s population order and capacity limits.

Replaces Mismatched or Smaller DDR5 RDIMM Sets

This kit replaces mixed-capacity modules, incomplete populations or slower DDR5 kits that force the controller to down-clock or disable slots. The jump is worth it when the workload demands the full 288GB at native DDR5-4800 throughput with registered ECC stability. It is not for systems requiring UDIMM, SODIMM or non-ECC memory, nor for boards that do not support 2Rx8 registered DDR5 at 1.1V.
