Product Identity

This NEMIX RAM kit delivers 1TB of DDR5 memory across eight 128GB registered ECC RDIMMs. It runs at 6400MHz with CL52 latency and operates at 1.1V using a 2Rx4 rank configuration on 288-pin modules. The kit is validated for the SuperMicro MP SuperServer SYS-242B-NR.

Who This Suits

System administrators expanding memory in the named SuperMicro SuperServer will find the exact capacity, speed and registered ECC format required. Buyers who need non‑ECC unbuffered DIMMs, lower voltages, different pin counts or speeds other than 6400MHz should look at other memory types.

Deciding Specification

The registered ECC RDIMM form factor with 2Rx4 organisation is the single specification that determines compatibility; only motherboards designed for registered DDR5 ECC modules can accept this kit.

Questions about this item

Does the kit come as eight 128GB modules ready to install, or do I need to buy anything else?

The package contains eight 128GB DDR5 RDIMM modules making a 1TB kit. No extra parts are required for installation.

Why choose the 1TB 6400MHz CL52 2Rx4 kit over a smaller capacity or different speed?

This kit delivers 1TB total capacity across eight registered ECC modules at 6400MHz with CL52 latency, matching the SuperMicro SYS-242B-NR specification.

What does the 6400MHz rating mean for actual throughput in a SuperMicro SYS-242B-NR?

The modules run at 6400MHz DDR5 with CL52 timing and 1.10V, providing the rated data rate when the server memory controller operates at that speed.
