NEMIX RAM
16 GB DDR4 2933 MHz ECC registered DIMM with CL21 latency for server upgrades
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.
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.
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.

The module runs at 2933 MT/s, delivering PC4-23400 bandwidth when the memory controller operates at that speed.
The registered buffer adds one cycle of latency, and ECC corrects single-bit errors while detecting multi-bit errors at the rated CL21 timing.
Yes, the 288-pin RDIMM matches the DDR4 server slot keying, and the bare PCB sits flush in the socket.
