Compatible SuperMicro DDR5 server memory

This NEMIX RAM module is a 64GB DDR5 4800 ECC RDIMM built for SuperMicro CloudDC SuperServer platforms. It operates at 1.1V with CL40 latency and uses a 2Rx4 registered design for stable operation in multi-socket environments. The 288-pin form factor matches the DDR5 server standard used in the listed systems.

Suited for administrators upgrading listed

IT teams managing SYS-621C-TN12R, SYS-611C-TN4R or SYS-121C-TN2R servers can add capacity with a module validated for those platforms. Builders who need unbuffered UDIMMs, non-ECC memory or a different speed grade should look at something else. The registered buffer and ECC function are mandatory for these motherboards.

64GB per module at DDR5 4800 with ECC

Each stick provides 64GB of registered DDR5 memory at 4800 MT/s with on-die error correction. That single specification — density combined with the registered ECC protocol — decides whether the part fits the memory subsystem of the target SuperMicro servers.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the memory slots on Supermicro SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R servers?

Yes, the 288-pin DDR5 RDIMM is designed for those Supermicro CloudDC SuperServer models and matches the DDR5 4800 registered DIMM slot keying.

What is the correct seating procedure for this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module height is even; the step often missed is confirming both clips have fully locked.

When should the 64GB 2Rx4 DDR5 ECC RDIMM be replaced in a 24/7 server workload?

Replace if ECC correctable-error counters rise steadily, if memory diagnostics report uncorrectable errors, or if the module fails POST after a firmware update.
