NEMIX RAM 48GB DDR5 4800 PC5-38400 2Rx8 CL40 1.1V ECC RDIMM Supermicro H13SST-GC memory upgrade

Exact-fit DDR5 upgrade for Supermicro H13SST-GC

This 48GB DDR5 4800 PC5-38400 registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It delivers 48GB at 1.1V with CL40 latency in a 2Rx8 configuration. The module is intended for servers and workstations that require registered memory with error correction.

Straightforward DIMM installation

The 288-pin RDIMM seats in the standard DDR5 slots on the H13SST-GC board. Because the platform uses registered memory, every slot can run fully populated at rated speed when the correct population order is followed. The most common issue is inserting modules in the wrong sequence or mixing ranks, which prevents the system from recognising the full capacity. No heat spreader is fitted, so clearance is minimal, but the motherboard manual must be consulted for the approved slot order before fitting.

Verify capacity limits

Check the Supermicro H13SST-GC manual for the maximum supported capacity per DIMM and the required population sequence for 2Rx8 registered modules. Confirm the board's qualified vendor list includes this specification and that the BIOS version in use supports the full 48GB density. Systems that only accept unbuffered UDIMMs or SODIMMs cannot use this RDIMM.
