Server DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 64 GB of DDR5 registered ECC memory in a matched set of four 16 GB modules. It is built for the Supermicro H13SRH motherboard and runs at 6400 MT/s with CL52 latency at 1.10 V. The registered design and error correction keep data stable in production environments.

Motherboard and population check

Verify that your H13SRH revision supports 1Rx8 registered DIMMs at 6400 MT/s and confirm the approved slot population order in the system manual. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function. Ensure the BIOS is updated to a version that recognises the full 64 GB capacity.

Enterprise server upgrades

This kit suits administrators expanding a Supermicro H13SRH platform to its supported memory limit with validated ECC RDIMMs. It is not intended for desktop boards that only accept unbuffered memory or for systems requiring higher-capacity modules than 16 GB per slot.

Questions about this item

What comes in the box and do I need anything else to install it?

The kit contains four 16 GB DDR5-6400 CL52 288-pin ECC RDIMM modules for a total of 64 GB. No additional parts are required; the modules plug directly into the Supermicro H13SRH motherboard DIMM slots.

Why choose this 4 x 16 GB kit instead of a different capacity?

This 64 GB kit matches the H13SRH memory population rules with four single-rank 1Rx8 modules at 1.1 V, delivering the full rated DDR5-6400 speed when all slots are populated.

What does the DDR5-6400 rating mean once the memory is running in my server?

The modules operate at 6400 MT/s with CL52 latency at 1.1 V, providing the bandwidth and error-correction the H13SRH platform expects for stable, fully populated operation.
