32 GB DDR4 2666 ECC RDIMM module

This single 32 GB registered DIMM runs at DDR4 2666 (PC4-21300) with CL19 latency and 1.20 V operation. It is built with ECC and a 2Rx4 organisation for server and workstation platforms that require error correction and signal buffering.

Compatibility check before ordering

Verify that your motherboard accepts DDR4 288-pin registered ECC memory and supports 2Rx4 modules at 2666 MT/s. Systems limited to unbuffered UDIMMs or to a lower maximum module density will not recognise this stick.

Thermals noise and power in normal use

Standard 1.20 V DDR4 voltage keeps power draw low and heat output minimal under typical server loads. Passive cooling from chassis airflow is sufficient; the module adds no audible noise to the system.
