16GB DDR5 ECC RDIMM for Thinkmate Supermicro Servers

This registered DDR5 module delivers 16 GB of error-correcting memory at 4800 MHz with CL40 latency. It operates at 1.1 V and uses a 288-pin RDIMM form factor. The single-rank 1Rx8 design is built with major OEM chips from Samsung, Micron or Hynix. It targets Thinkmate Supermicro SuperServer 611C-TN4R and 621C-TN12R platforms requiring registered ECC memory.

Suited for Thinkmate SuperServer memory expansion

This module fits administrators upgrading compatible Thinkmate Supermicro SuperServer 611C-TN4R or 621C-TN12R systems that accept DDR5 4800 MHz registered ECC RDIMMs. It is not for desktop PCs, laptops or consumer motherboards that require unbuffered non-ECC memory. Buyers needing higher capacities per slot or lower latency timings should look at other configurations.

16 GB capacity with DDR5 4800 headroom

The 16 GB density handles typical virtualisation workloads, database buffers and multi-threaded server applications within a single slot. Registered signalling and on-die ECC maintain data integrity under sustained load. Systems requiring more than 16 GB per DIMM slot or faster memory speeds will exceed what this module provides.

Questions about this item

Does my server need a DDR5 RDIMM slot to accept this 288-pin 1Rx8 module?

Yes, this is a 288-pin DDR5 RDIMM, so the system must provide a DDR5 RDIMM slot for it to fit and function.

Can I mix this 4800 MHz CL40 RDIMM with slower registered DDR5 modules already in the server?

All installed DDR5 RDIMMs will run at the speed and timings of the slowest module, so this 4800 MHz CL40 stick will downclock to match slower registered memory.

After installation, how can I confirm the 16 GB ECC registered module is active?

The system BIOS or OS memory report should show 16 GB of registered ECC DDR5 running at 4800 MHz with CL40 latency.
