16GB DDR4 2666MHz ECC RDIMM

This 16GB DDR4 2666MHz ECC RDIMM module uses a registered design with 1Rx4 organisation and CL19 latency. It operates at the standard 1.20V DDR4 voltage and fits 288-pin DIMM slots. The module targets servers and workstations that require error-correcting registered memory for stable operation.

Replaces HP 815098-S21 850880-001 872837-091

The module serves as a compatible equivalent for HP part numbers 815098-S21, 850880-001 and 872837-091. It upgrades systems originally configured with lower-capacity or slower DDR4 registered DIMMs. The jump is worth it when the platform supports 2666MHz registered ECC memory and the workload demands higher single-module density.

DDR4 registered DIMM constraints

Registered DIMMs require a memory controller that supports buffered operation and cannot be mixed with unbuffered modules in the same channel. The DDR4 2666MHz speed ceiling is set by the platform's memory controller; faster modules will downclock to the highest supported rate. Buyers needing non-ECC or unbuffered memory for desktop platforms cannot use this module.

商品問答

Will this 288-pin DDR4 DIMM fit the memory slots in my HP server?

Yes — the module uses the standard DDR4 DIMM 288-pin form factor that matches the slots in HP systems designed for 815098-S21, 850880-001 or 872837-091 memory.

Do I need to configure anything in BIOS after installing this registered ECC module?

Install the DIMM with the server powered off; most HP platforms auto-detect the 2666 MHz CL19 1.20 V registered ECC timings, but verify the memory mode in BIOS if the system does not show the full 16 GB.

When should I expect to replace this 1Rx4 server memory module?

The module is rated for continuous server operation at 1.2 V DDR4 standard voltage; plan replacement only if diagnostics report correctable ECC errors rising or the system fails memory tests.
