Exact-match DDR5-6400 RDIMM kit

This NEMIX RAM kit delivers 384GB across four 96GB DDR5-6400 RDIMM modules rated at CL52 and 1.1V. Each module uses a 2Rx4 registered ECC design on a 288-pin form factor built with major OEM DRAM. The kit is validated for the Supermicro H13SSL-NT motherboard so the memory controller recognises the full capacity at rated speed without manual tuning.

Registered ECC with 2Rx4 organisation

Registered buffering reduces electrical load on the memory controller when all four slots are populated, allowing the full 384GB to operate at DDR5-6400. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads. The 2Rx4 rank structure matches the board's population rules for optimal signal integrity.

Suited for memory-intensive server deployments

This capacity and speed combination fits virtualisation hosts, database nodes and compute clusters that require maximum registered ECC density on the H13SSL-NT platform. Buyers needing unbuffered UDIMM or SODIMM form factors should look elsewhere, as those module types are physically and electrically incompatible with this motherboard.

Questions about this item

Will the 96 GB DDR5 RDIMM modules need a heat spreader added later for sustained 24/7 server operation?

The kit ships without heat spreaders; the registered DDR5 modules run at 1.1 V and rely on chassis airflow, so no additional spreader is required unless your enclosure has restricted circulation.

What limits total capacity first when all four slots of the Supermicro H13SSL-NT are populated with these 2Rx4 modules?

The motherboard's qualified-vendor list caps the system at 384 GB with four 96 GB RDIMMs, so the board's population rule is the limiting factor before the memory controller reaches its rank ceiling.

How much power and heat does the 384 GB kit draw at the rated 1.1 V during continuous all-day workloads?

Each 96 GB DDR5 RDIMM operates at 1.1 V, so the full four-module kit draws roughly 13 W combined, producing modest heat that standard server airflow handles without extra cooling.
