768 GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 768 GB of DDR5 memory across six 128 GB registered DIMMs. It operates at 6400 MHz with a CAS latency of 52 and a voltage of 1.10 V. The modules are built for Supermicro MP SuperServer SYS-242B-NR systems.

Registered ECC with major OEM chips

Each 288-pin RDIMM uses a 2Rx4 organisation and on-die ECC for data integrity in server workloads. The DRAM comes from Samsung, Micron or Hynix depending on supply. No heat spreaders are included, so airflow must be managed by the chassis.

Suited for high-capacity Supermicro servers

This kit fits administrators expanding memory in the named Supermicro platform. Buyers needing unbuffered UDIMMs, lower-density modules or memory qualified for other vendors should look elsewhere.

Questions about this item

Will the registered ECC RDIMM modules require any periodic maintenance or component replacement after installation?

Registered ECC RDIMM modules have no moving parts and need no scheduled maintenance or component replacement once correctly seated in the server.

What is the first limit reached when the 6400 MHz CL52 kit runs sustained workloads on the Supermicro SYS-242B-NR?

The CAS latency of 52 cycles at 6400 MHz sets the timing boundary that appears before thermal or power limits during continuous operation.

How much heat and power does the 768 GB kit produce when the Supermicro server runs all day at 1.1 V?

Each 128 GB module operates at 1.1 V without a heat spreader, so total power draw stays low and passive airflow in the chassis handles the heat.
