32GB DDR4 ECC RDIMM for HP servers

This 32GB DDR4 2666 MHz registered DIMM delivers error-correcting code memory for compatible HP server and workstation platforms. The module operates at 1.2V with CL19 latency and a 2Rx4 rank configuration. It is built as a direct replacement for HP part numbers 2660-0431, L09286-850 and P04177-001.

Standard voltage and registered buffering

Running at the DDR4 standard 1.2V, the module draws typical power for its density and speed class. Registered buffering reduces electrical load on the memory controller, which helps maintain signal integrity in multi-DIMM configurations. No active cooling or additional power circuitry is required beyond the server's standard DIMM slots.

Lifetime warranty and US-based support

A-Tech backs the module with a lifetime warranty and provides complimentary United States-based technical support before, during and after purchase. Every unit undergoes quality assurance testing to verify reliable operation. Buyers should confirm their system's supported memory specifications prior to ordering to ensure compatibility.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the 288-pin DDR4 RDIMM with the slot key, press firmly until both retention clips click, then verify the system recognises the full 32GB capacity and ECC functionality in BIOS.

What maintenance or replacement will this 32GB ECC RDIMM need over time?

No scheduled maintenance is required; if a correctable error count rises or the module fails, replace the 32GB DDR4 2666 RDIMM with an identical 2Rx4 1.20V part.

What limit appears first when this CL19 2666MHz RDIMM runs sustained workloads?

The CL19 latency at 2666MHz sets the throughput ceiling; sustained heavy loads will hit bandwidth limits before thermal throttling on this 1.20V registered module.
