A-Tech 32GB DDR4 2666 ECC RDIMM 2Rx4 HP 1XD86AA 864708-591 server RAM

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.
