384GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 384GB of DDR5 4800 memory across twelve 32GB registered DIMMs. It is built for Supermicro CloudDC SuperServer platforms including the SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R. The modules run at 1.1V with CL40 latency and use 1Rx4 organisation.

Suits registered DDR5 servers only

IT teams managing compatible Supermicro CloudDC SuperServer systems can use this kit to maximise memory capacity with ECC protection. Workstations or desktops that require unbuffered UDIMMs or a different DDR generation cannot use these registered modules.

288-pin DDR5 RDIMM form factor

Each module uses the 288-pin DDR5 RDIMM interface, so the motherboard must provide registered DDR5 slots. A board wired for UDIMMs or an earlier DDR generation will not accept this kit.

Questions about this item

Does my SuperMicro server need all 12 DIMM slots free to install this 384GB kit?

The kit contains 12 modules of 32GB each, so the host must provide 12 available 288-pin DDR5 RDIMM slots.

Will these registered ECC RDIMMs work in a SuperMicro system that currently runs unbuffered ECC UDIMMs?

No, the modules are registered (RDIMM) with a 1Rx4 layout and 1.10V operation; they cannot be mixed with unbuffered UDIMMs.

How can I confirm the kit is running at the rated DDR5 4800 CL40 speed after installation?

Check the BIOS or OS memory report for PC5-38400 frequency and CAS latency 40 on all 12 modules.
