64 GB DDR5 ECC RDIMM Kit for SuperMicro

This 64 GB kit contains four 16 GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for SuperMicro Hyper SuperServer systems such as the SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R that require registered error-correcting memory.

Installation is tool-free and takes minutes

Align each 288-pin module with the slot key and press firmly until the retention clips lock. The most common issue is mixing registered DIMMs with unbuffered memory or populating slots in an order the motherboard manual does not support.

Verify your server model and slot population rules

Confirm the exact SuperMicro system matches the listed compatible models and check the manual for required DIMM placement per channel. Ensure the platform supports 1.1 V DDR5 registered modules and that all four slots can accept 1Rx8 organisation.

Questions about this item

How can I confirm the DDR5 4800 CL40 ECC RDIMM kit is running correctly after installation?

Enter the server BIOS or use a hardware monitoring tool to verify the memory reports 4800 MT/s, CL40 timings, 1.10 V operation and that ECC is active across all four modules.

What comes in the box with the NEMIX RAM 64 GB kit and what must be purchased separately?

The package contains four 16 GB DDR5 4800 CL40 288-pin ECC RDIMM modules; no cables, brackets or additional components are included and nothing else is required for installation.

Which capacity version of this SuperMicro-compatible DDR5 RDIMM kit should I choose for a SYS-221H-TNR?

The 64 GB (4 × 16 GB) kit matches the four-channel architecture of the SYS-221H-TNR and provides 1Rx8 registered ECC modules at the supported 4800 MT/s speed.
