Server-grade DDR5 kit for Supermicro H13SST-GC

This 384GB kit delivers six 64GB DDR5-6400 registered ECC RDIMMs tuned to the exact rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It is built for operators who need full-capacity population across all slots in production servers and workstations. Buyers who need unbuffered UDIMMs or laptop SODIMMs cannot use this kit.

Registered architecture

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 6400 MT/s without down-clocking. The 1.10V operating voltage keeps power draw modest even with all six modules installed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. No heat spreaders are fitted, so airflow across the bare PCBs must be maintained by the chassis fans.

288-pin RDIMM form factor and population rules

The 288-pin registered DIMM form factor matches the board's physical slots and electrical requirements precisely. Installation must follow the motherboard manual's approved population order to achieve the full 384GB at rated speed. Mixing these modules with different ranks, voltages or timings will break compatibility. The kit contains only the six RDIMMs; no extra brackets, cables or software are included.

Questions about this item

How do I install the 6x64GB DDR5 6400 RDIMM kit in the Supermicro H13SST-GC and what step is often missed?

Power off the server, open the chassis, and insert each 288-pin module into the slots listed in the motherboard manual for a 6-DIMM population; the step most often missed is confirming the exact slot order before seating all six sticks.

What maintenance or replacement will the NEMIX RAM 384GB DDR5 ECC RDIMM kit need later?

No routine maintenance is required; if a module fails the lifetime replacement warranty covers a swap, otherwise the kit runs until a capacity upgrade is desired.

What limit appears first when the 384GB DDR5 6400 CL52 1.1V RDIMM kit runs under sustained load?

The memory controller's maximum supported capacity and population rules for the H13SST-GC are the first ceiling; the kit operates at its rated 6400 speed and 1.1V within those limits.
