NEMIX RAM
Registered DDR4 ECC RDIMM module with 16 GB capacity, 3200 MHz speed and CL22 latency for Micron-compatible servers
This registered DDR4 module provides 16GB of ECC server memory at 3200MHz with CL22 latency. It targets IT professionals maintaining Micron-compatible servers and workstations that require registered DIMMs for data integrity. The 1Rx4 organisation and 1.2V operation match the Micron MTA18ASF2G72PZ-3G2 specification for direct replacement.
The module fits standard 288-pin DDR4 RDIMM slots and requires no heat spreader clearance. Registered signalling means the memory controller must support buffered DIMMs; desktop consumer boards that accept only unbuffered memory will not POST with this module. Always verify the system manual lists RDIMM support and the correct population order before inserting the stick.
Rigorous stress testing under load validates stability for continuous enterprise workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute or storage tasks. Registered buffering reduces electrical load on the memory bus, helping maintain signal quality when multiple DIMMs populate the server over extended periods.

Enter the server BIOS or UEFI and confirm the memory frequency reads 3200MHz with CAS latency 22; the registered ECC design will also report corrected errors in system logs if it is functioning.
The box contains one 1Rx4 288-pin RDIMM at 1.2V; no heat spreader, cables, or tools are included, so have a compatible registered DIMM slot and your system manual ready.
Select this 16GB stick when your Micron-compatible server or workstation requires registered ECC DDR4 at 3200MHz and you need a single-rank 1Rx4 configuration for maximum slot density.
