384GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit delivers 384GB of DDR5 memory in six 64GB registered DIMMs. Each module runs at 4800 MT/s with CL40 latency at 1.1V. The 2Rx4 organization and ECC protection are built for Supermicro GPU SuperServer platforms including the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT.

Suited for Supermicro GPU servers needing maximum

The six-module kit fills all slots in supported Supermicro systems that accept 64GB RDIMMs. Builds requiring fewer than six modules, non-ECC memory, unbuffered DIMMs or speeds above 4800 MT/s should select a different configuration. Workstations without registered-DIMM support cannot use these modules.

Registered ECC with 2Rx4 organization

The RDIMM register and on-die ECC provide the signal integrity and error correction required by the target Supermicro platforms. Systems that require unbuffered UDIMMs, LRDIMMs or a different rank structure will not accept this kit.

Questions about this item

How can I verify the 384GB kit is running at 4800 MT/s with CL40 timings after installation?

Enter the server BIOS or use a tool such as CPU-Z to confirm the memory operates at 4800 MT/s and shows CL40 latency for each of the six modules.

What exactly ships in the box and is any extra hardware required?

The package contains six 64GB DDR5 4800 ECC RDIMM modules (2Rx4, 1.10V, 288-pin) — no cables, brackets or additional parts are included or needed.

Which capacity version should I choose for a Supermicro SYS-821GE-TNHR that supports up to 384GB?

Select this 384GB (6×64GB) kit to populate all six channels at the maximum supported density for that platform.
