16 GB DDR4-2666 ECC RDIMM

This 16 GB DDR4-2666 ECC Registered RDIMM is built for servers and workstations that require error-correcting memory. It fits 288-pin DDR4 slots and operates at 1.2 V with a CL15 latency. The module uses a 1Rx4 rank configuration and major-brand chips.

Thermals and power in normal use

The module runs at the standard DDR4 voltage of 1.20 V, keeping power draw low inside a populated chassis. Registered buffering reduces electrical load on the memory controller, which helps maintain stable temperatures during sustained workloads. No active cooling is required on the DIMM itself.

Single spec that decides fit

The part is validated as 100 % compatible with HP part number 872970-001 and meets or exceeds the original OEM specifications. If your system calls for that exact HP part number, this module will work and will preserve your existing service contract. Buyers who need a different HP part number or a non-HP platform should verify their own qualified-vendor list before ordering.

Questions about this item

How is the 288-pin DDR4 RDIMM seated, and what step do people miss?

Align the notch with the slot key, press straight down until both retention clips click, then verify the module sits flush; the step often skipped is confirming the clips have fully engaged on both sides.

What maintenance or replacement will the 1Rx4 ECC registered module need later?

No routine maintenance is required; if a correctable error count rises or the server logs uncorrectable ECC events, replace the affected 16 GB stick.

What limit appears first when the PC4-21300 CL15 1.2 V kit runs sustained workloads?

The JEDEC 1.20 V operating voltage and CL15 timing set the thermal and stability ceiling; prolonged heavy use will hit the module's rated speed and latency envelope before any other constraint.
