16GB DDR4 2666 ECC RDIMM

This 16GB DDR4 2666 registered DIMM provides error-correcting memory for servers and workstations that require data integrity. It operates at 1.20V with CL19 latency and uses a 2Rx8 organisation built on Micron chipset. The module fits 288-pin DIMM slots and replaces several Micron part numbers.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller, helping stability during continuous workloads such as virtualisation or database tasks. ECC detects and corrects single-bit errors without halting the system. The 1.20V standard voltage keeps power draw predictable over long periods.

Compatibility checks

Verify that your motherboard supports DDR4 registered ECC DIMMs and accepts 2Rx8 modules at 2666 MT/s. Confirm the platform can address 16GB per slot and that the BIOS is configured for registered memory. Ensure the 288-pin form factor matches your DIMM slots before ordering.

Questions about this item

How much power does this 1.20V DDR4 2666 module draw when the server runs continuously?

It operates at the standard DDR4 voltage of 1.20V; actual power draw depends on your platform and workload, but the module itself is rated for that voltage.

What must my motherboard provide to run this 288-pin ECC RDIMM?

A DDR4 DIMM slot that supports registered ECC memory at 2666 MT/s and can supply 1.20V to the module.

Will this CL19 2Rx8 module work in a system that already has DDR4 2666 ECC RDIMMs installed?

Yes, provided the board supports registered ECC DDR4 at 2666 MT/s; mixing ranks or CAS latencies may force the channel to run at the slowest common settings.
