16 GB DDR5 ECC RDIMM for Supermicro servers

This registered DDR5 module delivers 16 GB at 4800 MT/s with ECC protection and a CL40 latency. It operates at 1.1 V and uses a 1Rx8 organisation on a 288-pin form factor. The part is validated for Supermicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R platforms.

Suits IT teams upgrading compatible Supermicro

Administrators needing registered ECC memory for the listed Supermicro CloudDC SuperServer models can install this module directly. Buyers whose servers require UDIMM or LRDIMM form factors, a different DDR5 speed grade, or a higher capacity per slot should select an alternative part.

Registered ECC RDIMM 288-pin DDR5 at 4800 MT/s

The registered buffer and on-die ECC make this module compatible only with motherboards that support DDR5 RDIMM memory. Systems that accept only unbuffered UDIMM modules or a different DDR generation will not recognise the part. Verify the server memory specification before ordering.

Questions about this item

Will this DDR5 4800 RDIMM install in a SuperMicro CloudDC SuperServer SYS-621C-TN12R alongside existing DDR5 modules?

Yes, it is listed as compatible with the SYS-621C-TN12R and other CloudDC SuperServer models; all installed DDR5 RDIMMs must share the same speed, voltage, and registered ECC specification.

How can I confirm the module is running at DDR5 4800 with ECC active after installation?

Check the BIOS memory information or operating system hardware report for a speed of 4800 MT/s, CL40 latency, 1.10 V voltage, and ECC status shown as enabled or active.

What is included in the package and are any extra parts required for installation?

The box contains one 16 GB 288-pin DDR5 RDIMM; no additional components are needed if the server has free DIMM slots that support registered ECC memory.
