384GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 384GB across four 96GB registered DIMMs built for the Supermicro SYS-242B-NR. Each module runs at 6400MHz with CL52 latency at 1.1V using 2Rx4 organisation. ECC and registered buffering protect data integrity in continuous server workloads.

Enterprise Servers Needing Maximum Capacity

The 384GB kit suits administrators populating every slot of a compatible Supermicro platform for virtualisation, databases or large in-memory datasets. Systems that cannot accept registered ECC RDIMMs or that require lower-density modules should consider other configurations.

Four 96GB Modules at 6400MHz

The kit fills four slots with 96GB each, providing 384GB total headroom for heavy multi-tenant or analytics workloads. Capacity limits are reached when the platform slot count or memory-controller ceiling is met, so verify the Supermicro SYS-242B-NR maximum before purchase.

Questions about this item

What motherboard slot type does this 288-PIN DDR5 RDIMM kit require?

The modules fit a 288-PIN DDR5 RDIMM slot on the Supermicro SYS-242B-NR motherboard.

Can I mix these CL52 6400MHz modules with slower DDR5 RDIMMs already installed?

The system will downclock all modules to the speed of the slowest installed kit.

How can I confirm the 4x96GB kit is recognised correctly after installation?

The BIOS memory summary should show 384GB total capacity with ECC enabled.
