HP-Compatible 16 GB DDR4-2666 RDIMM

This registered ECC module delivers 16 GB of DDR4-2666 memory at 1.20 V with CL15 latency. It uses a 288-pin 1Rx4 layout built on major-brand DRAM chips. The part matches HP part number 815098-S21 and is guaranteed compatible with systems that accept this specification.

For servers needing registered ECC memory

Suits administrators expanding HP or compatible platforms that require registered DDR4-2666 ECC RDIMMs. Not for workstations or desktops that only accept unbuffered UDIMMs. Not for systems limited to lower speeds or different voltages. Buyers needing larger single-module capacities should look elsewhere.

100 % HP-compatible assurance

Third-party manufacturing uses the same major-brand components as OEM modules, preserving existing service contracts. Lifetime warranty covers the module for the duration of ownership. No additional software or accessories are bundled with the memory stick.

Questions about this item

Does this DDR4-2666 RDIMM require a server motherboard with 288-pin DDR4 slots that support ECC registered memory?

Yes, the module is a 288-pin DDR4 RDIMM with ECC and registered buffering, so the board must provide DDR4 slots that accept registered ECC DIMMs.

If I add this 1Rx4 CL15 module to existing DDR4-2666 RDIMMs, will it run at the same speed and latency?

The module is rated DDR4-2666 (PC4-21300) CL15 at 1.2 V; the system will operate all installed DIMMs at the lowest common speed and latency.

How can I confirm the module is recognised as 16 GB ECC registered at 2666 MT/s after installation?

Check the BIOS memory information or run a system tool such as dmidecode to verify capacity, speed, ECC status and registered type.
