16GB DDR4 2666 ECC RDIMM for Micron servers

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.

Replaces non-ECC or slower registered modules

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.

Verify RDIMM support and slot population rules

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.

Questions about this item

Will this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

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.

What is the correct way to seat this registered ECC module so the register initializes?

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.

How can I tell if the Samsung, Micron or Hynix chips on this stick are degrading over time?

Monitor the system event log for corrected ECC errors; a rising count indicates the 2Rx8 chips are wearing and the module should be swapped.
