16GB DDR4-2666 ECC Registered DIMM

This 16GB DDR4-2666 module delivers error-correcting, registered memory for servers and workstations that require data integrity. It operates at 1.20V and carries Supermicro certification for qualified platform compatibility. The PC4-21300 rating confirms its standard transfer rate for DDR4-2666 systems.

Build integration and capacity planning

The registered buffer reduces electrical load on the memory controller, allowing higher total system capacities than unbuffered alternatives. ECC functionality detects and corrects single-bit errors to maintain uptime in critical workloads. Systems must support DDR4 registered DIMMs and ECC to use this module; consumer platforms without those features cannot accept it.

Thermals, noise and power draw

Standard 1.20V DDR4 voltage keeps power consumption low for high-density server deployments. Passive operation produces no acoustic noise, relying on chassis airflow for cooling. The registered design adds minimal latency overhead while stabilising signal integrity across fully populated memory channels.

Questions about this item

How does the 1.20V registered design affect heat output when the 16GB DDR4-2666 module runs continuously in a full bank?

The 1.20V operating voltage and registered architecture keep power draw low per module, so a full bank generates modest heat that standard server airflow can dissipate without extra cooling.

What motherboard features must already be present for this ECC registered DIMM to function?

The board must provide DDR4 slots that support registered ECC memory and accept PC4-21300 speeds.
