16 GB DDR4 ECC RDIMM for Micron servers

This 16 GB registered DDR4 module is built for Micron server and workstation platforms that require ECC error correction. It operates at 2933 MHz with CL21 latency and a standard 1.20 V supply, using a 2Rx8 organisation across 288 pins. The module is designed for IT professionals who need validated compatibility in mission-critical environments.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the registered ECC RDIMM interface combined with a 2Rx8 rank structure. Systems expecting unbuffered UDIMM modules or a different rank configuration will not accept this part. Micron-compatible motherboards that list PC4-23400 registered memory are the intended platform.

16 GB per module with headroom for multi-slot

One module delivers 16 GB of capacity; populating additional slots scales total memory in 16 GB increments up to the platform limit. The DDR4 2933 speed rating provides bandwidth headroom for typical virtualization and database workloads, while the registered buffer reduces electrical load on the memory controller. Buyers who need densities beyond 16 GB per slot or faster DDR5 transfer rates must select a different module type.

Questions about this item

What does the 2933 MHz rating mean when the module is installed in a server?

The module runs at 2933 MT/s, delivering PC4-23400 bandwidth when the memory controller operates at that speed.

How does the registered ECC interface affect usable speed and error handling?

The registered buffer adds one cycle of latency, and ECC corrects single-bit errors while detecting multi-bit errors at the rated CL21 timing.

Will the 288-pin RDIMM fit in a standard server DIMM slot without a heat spreader?

Yes, the 288-pin RDIMM matches the DDR4 server slot keying, and the bare PCB sits flush in the socket.
