NEMIX RAM 384GB 8x48GB DDR5 6400 CL52 2Rx8 ECC RDIMM Supermicro H13SSW memory upgrade

Exact-match DDR5-6400 RDIMM kit

This 384GB kit contains eight 48GB DDR5-6400 RDIMMs built to the Supermicro H13SSW motherboard's exact rank, voltage, and timing requirements. Registered ECC architecture with CL52 latency at 1.1V ensures the memory controller recognises full capacity and runs at rated speed. It is designed for administrators upgrading that specific server platform. Builders needing a different form factor, unbuffered DIMMs, or lower-density modules should look elsewhere.

Sustained-load behaviour

Registered buffering offloads the memory controller so all eight slots remain stable at full population during continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots that would otherwise reach production. The 1.1V operating voltage keeps power draw consistent across extended duty cycles. Systems requiring higher frequencies or tighter latencies than CL52 will not be satisfied by this specification.

Installation and common issues

The 288-pin RDIMM form factor fits only boards that mandate registered memory; it will not seat in UDIMM or SODIMM slots. Population order and maximum supported capacity vary by motherboard revision, so the system manual must be consulted before installation. A mismatched population sequence is the most frequent cause of POST failure or reduced recognised capacity. No heat spreader is included, so airflow across the modules must be adequate for the chassis design.
