Server-grade DDR4 ECC RDIMM

This 32 GB DDR4 2666 MHz registered DIMM delivers error-correcting memory for HP server and workstation platforms. It operates at 1.20 V with CL19 latency and a 2Rx4 organisation using major-brand chips. The module suits administrators who need validated capacity expansion for compatible HP systems.

Sustained-load stability

Registered buffering and ECC circuitry maintain data integrity during continuous multi-threaded workloads such as virtualisation, database serving or render farms. The single 32 GB stick populates one 288-pin slot without increasing per-module power draw beyond the standard DDR4 voltage.

DDR4 platform ceiling

DDR4 2666 represents the upper JEDEC speed tier for this generation, so the module cannot exceed PC4-21300 bandwidth on any platform. Systems limited to lower DDR4 frequencies will down-clock the DIMM automatically, and boards that require unbuffered UDIMMs or a different rank configuration will not accept it.

Questions about this item

How much power does the 32GB DDR4 2666 ECC RDIMM draw at its 1.20V operating voltage?

The module runs at the standard DDR4 voltage of 1.20V, keeping power draw low for continuous server workloads.

What motherboard slot and memory-channel support are needed to install this 288-pin DDR4 RDIMM?

A DDR4 RDIMM-compatible 288-pin DIMM slot on a server or workstation motherboard that supports registered ECC memory is required.

Will this 2Rx4 registered ECC module work alongside existing 1Rx4 or 2Rx8 DDR4 2666 RDIMMs in the same HP server?

Mixing ranks is often possible, but the system BIOS and memory controller must support the combined rank population; verify the platform's qualified vendor list first.
