NEMIX RAM
16 GB DDR4-3200 ECC registered DIMM for Micron-compatible servers, CL22 at 1.2 V
This 16 GB DDR4 module delivers registered ECC operation at 3200 MT/s for Micron-compatible servers and workstations. The 2Rx8 organisation and CL22 latency support data-integrity workloads where error correction is mandatory.
The RDIMM register buffers address and command signals, reducing electrical load on the memory controller in multi-module configurations. A standard 1.20 V supply and 288-pin edge connector allow direct installation in compatible DDR4 server DIMM slots without extra cabling.
DDR4 tops out at 3200 MT/s JEDEC speeds, so this module reaches the interface ceiling. Builders needing higher bandwidth or greater density per slot must move to a DDR5 platform, which requires a new motherboard and CPU.

The module is specified at DDR4 3200 with a PC4-25600 designation, which indicates its rated transfer speed.
It fits a standard DDR4 288-pin RDIMM socket; the registered design and 2Rx8 organisation mean the motherboard must support registered ECC memory.
Power down the system, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until the retention clips lock, then verify the module is recognised in BIOS.
