Exact-match server kit

This NEMIX RAM kit delivers 288 GB of DDR5 registered ECC memory in six 48 GB modules. It is built for the Supermicro H13SRH motherboard and runs at 6400 MT/s with CL52 latency at 1.1 V. The 2Rx8 registered design matches the board's memory controller requirements for full-capacity recognition.

Registered ECC architecture

Registered buffering offloads the memory controller so all slots can be populated at rated speed without signal degradation. On-die ECC corrects single-bit errors in flight, protecting data integrity in production workloads. The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots.

Suited for capacity-bound servers

This kit suits administrators who need the maximum validated capacity on an H13SRH platform and require ECC protection for continuous operation. It is not for builds that need unbuffered modules, lower voltages, or consumer desktop boards that lack registered DDR5 support.

Questions about this item

Will the CL52 latency at 6400 MHz hold steady when all six slots on the Supermicro H13SRH are populated?

The kit is specced at CL52 for DDR5 6400 operation, and the registered design is built to maintain those timings across a fully populated six-DIMM configuration on the H13SRH.

How much heat and power should I expect from a 1.10 V, 288 GB RDIMM kit running continuously in a server chassis?

Each 48 GB module runs at 1.10 V without a heat spreader; registered buffering reduces electrical load on the memory controller, so total power draw and thermals stay within standard DDR5 RDIMM limits for dense 6-channel setups.

Does the Supermicro H13SRH need a specific BIOS revision or CPU stepping to recognise 48 GB 2Rx8 RDIMMs at full 6400 speed?

The kit is validated for the H13SRH motherboard; the board's own memory-population rules and supported DIMM configurations determine which BIOS or CPU revisions are required for full-speed recognition.
