32GB DDR4 2666MHz ECC RDIMM for HP Servers

This 32GB registered DIMM operates at DDR4 2666MHz with CL19 latency and 1.2V power. It is built for server and workstation systems that require error-correcting memory and registered signal buffering. The module replaces specific HP part numbers including P05590-H21 and 815100-B21.

Single module simplifies capacity planning

Supplied as a single 32GB stick, this module lets administrators add capacity in precise increments without populating multiple slots. The 2Rx4 organisation and major-brand chipset deliver the density needed for virtualisation hosts and database workloads. No extra cables, brackets or software licences are included in the package.

DDR4 2666MHz registered interface sets bandwidth

The PC4-21300 standard limits peak throughput to the rated 2666MHz transfer rate, so systems incapable of this speed will downclock the module. Registered signalling adds one clock cycle of latency compared with unbuffered DIMMs, which affects timing-sensitive applications. Compatibility depends on the platform's qualified-vendor list, not on the DDR4 form factor alone.

Questions about this item

Will the 32GB DDR4 2666MHz ECC RDIMM need any maintenance or replacement during its service life?

No routine maintenance is required for this 32GB DDR4 2666MHz ECC RDIMM; the module is tested before shipping and covered by a lifetime warranty, so it is replaced only if a fault develops.

What limit appears first when the 2Rx4 registered DIMM runs at full 2666MHz load for extended periods?

The registered buffer adds one clock cycle to every command, making command latency the first bottleneck before bandwidth or thermal limits are reached.

How much heat and power does the 1.2V 288-pin DDR4 module produce when it runs all day in a server?

At the standard 1.2V DDR4 voltage the 32GB module draws only a few watts and generates minimal heat, so standard server airflow keeps it well within safe temperatures.
