16GB DDR4 ECC RDIMM for HP servers

This 16GB DDR4 2666MHz ECC registered DIMM is built for HP server and workstation platforms. It delivers 1Rx4 organisation at CL19 latency and 1.20V operation. The module suits administrators expanding memory capacity in compatible enterprise systems.

Check HP part numbers and slot availability

Verify that your system lists HP part numbers L09285-850 or 864707-591 in its qualified memory list. Confirm the motherboard accepts 288-pin DDR4 RDIMMs and has a free DIMM slot. Registered ECC memory must be supported by the platform chipset and BIOS.

Replaces HP L09285-850 and 864707-591 modules

This A-Tech module directly replaces the HP L09285-850 and 864707-591 16GB DDR4 2666MHz ECC RDIMMs. The upgrade is worth it when your workload demands additional registered ECC capacity and the existing slots are populated with lower-density modules.

Questions about this item

Does the 16GB DDR4 2666MHz ECC RDIMM ship as a single 288-pin module or do I need to order a kit?

The item is a single 16GB module (1x 16GB) in a 288-pin DIMM form factor; no additional parts are included.

When should I choose the 1Rx4 registered ECC version over other ranks or unbuffered types?

Select 1Rx4 registered ECC when your server or workstation requires registered DIMMs with error correction and a single-rank x4 organisation for maximum capacity per channel.

What does the 2666MHz PC4-21300 rating mean for actual server workloads?

The module runs at 2666MHz with CL19 latency at 1.2V, delivering the standard DDR4 bandwidth and error-corrected stability expected in qualified server platforms.
