128GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 4800 registered ECC memory across eight 16GB modules. It is built for SuperMicro CloudDC SuperServer platforms including the SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R. The modules run at 1.10V with CL40 latency and use a 288-pin RDIMM form factor.

Suited for administrators expanding compatible

This kit suits IT teams adding maximum capacity to the listed SuperMicro CloudDC SuperServer models where registered ECC DDR5 is required. It is not for desktop PCs, workstations or laptops that accept only unbuffered UDIMM memory. Buyers needing lower densities, different speeds or non-ECC modules should look at other configurations.

Registered ECC DDR5 at 4800MT/s decides fit

The single specification that determines compatibility is the registered ECC DDR5 4800 standard with 1Rx8 organisation and 1.10V operation. Only systems qualified for this exact module type and pin-out will accept the kit. Verify the server memory list before ordering to ensure the platform supports 128GB in this configuration.

Questions about this item

How much power does the 1.10 V DDR5 kit draw under continuous load?

Each 16 GB module runs at 1.10 V; total draw depends on the server's memory controller and workload, so consult the SuperMicro platform specifications for exact figures.

Which SuperMicro systems must I already have for this 288-pin RDIMM kit to function?

The kit is validated for SuperMicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R platforms.

Will the CL40 registered ECC modules work alongside other DDR5 DIMMs I keep in the same server?

Mixing ranks, speeds or vendors can prevent the system from posting; for stability, populate all channels with identical 1Rx8 4800 CL40 modules.
