NEMIX RAM
16 GB DDR4-2666 ECC registered DIMM, CL19 1.2 V, 2Rx8 288-pin for server upgrades
This registered DIMM adds 16GB of error-correcting DDR4 memory to compatible Micron server and workstation platforms. It operates at 2666MHz with CL19 latency and 1.2V power draw. The 2Rx8 organisation suits multi-channel configurations in enterprise environments.
Upgrading from unbuffered or lower-speed RDIMMs is worthwhile when the workload demands data integrity and the motherboard supports registered ECC memory. The jump makes sense for virtualisation hosts, database servers or NAS appliances that must tolerate single-bit errors without crashing.
Confirm the target system accepts 288-pin DDR4 RDIMMs and that the memory controller supports 2Rx8 modules at 2666MHz. Check the vendor documentation for maximum capacity per channel and required slot-filling order before ordering.

Yes, the module uses the 288-pin DDR4 RDIMM form factor and requires a matching registered DIMM slot on a compatible server or workstation motherboard.
Align the notch with the slot key, press straight down until both side latches click shut, then power on so the register can train at 2666 MT/s.
Monitor the system event log for corrected ECC errors; a rising count indicates the 2Rx8 chips are wearing and the module should be swapped.
