128 GB DDR5 RDIMM for Supermicro servers

This NEMIX RAM module delivers 128 GB of DDR5 4800 memory in a single 288-pin registered DIMM. It operates at 1.1 V with CL40 latency and includes ECC and 4Rx4 organisation for data-integrity workloads. The part is validated for Supermicro CloudDC SuperServer platforms including the SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R.

Upgrade path from lower-capacity DDR5 RDIMMs

Replacing smaller registered modules with this 128 GB stick increases total memory without consuming additional slots. The jump is worthwhile when applications demand larger in-memory datasets or higher virtual-machine density and the platform supports 4Rx4 registered DIMMs at 4800 MT/s.

Suited for IT teams expanding Supermicro CloudDC

Administrators scaling memory in the listed SuperServer models can add this module directly. Builders needing unbuffered UDIMMs, non-ECC memory, speeds above 4800 MT/s or capacities beyond a single 128 GB DIMM should evaluate other options.

Domande su questo articolo

Does the 288-pin DDR5 RDIMM fit the SuperMicro CloudDC SuperServer SYS-621C-TN12R memory slots?

Yes, this module is built to the DDR5 RDIMM form factor and matches the pinout and keying used by the SYS-621C-TN12R memory slots.

What is the correct way to seat the 1Rx4 registered DIMM so the ECC register initialises?

Align the notch with the slot key, press straight down until both retention clips click, then verify in BIOS that the module reports 4800 MT/s and ECC active.

When should the 128 GB module be replaced based on ECC health monitoring?

Replace the module if the system logs show increasing correctable ECC error counts or if a firmware update changes the supported memory configuration.
