16GB DDR4 2400 ECC RDIMM for HP Servers

This 16GB registered DDR4 module delivers ECC error correction for HP server and workstation platforms. It replaces HP part numbers 805349-S21, 809082-091, 809082-591, 843313-S21 and 861109-001. The single-rank 1Rx4 design uses major-brand chips at 1.20V standard voltage.

Capacity and registered buffer headroom

The 16GB capacity suits virtualization hosts, database nodes and multi-user application servers that benefit from registered signal integrity. CL17 latency at 2400 MT/s provides stable throughput for typical enterprise workloads. Systems requiring higher density per slot or faster data rates will exceed this module's specifications.

DDR4 288-pin RDIMM interface limits

The DDR4 288-pin RDIMM form factor fits only DDR4 registered DIMM slots; it will not work in unbuffered UDIMM or LRDIMM sockets. PC4-19200 rating defines the maximum standard transfer rate; overclocking beyond 2400 MT/s is not supported by the JEDEC specification for this module.

Questions about this item

Will this 1Rx4 DDR4 2400 ECC RDIMM run with my existing CL17 1.20V modules in a multi-channel server?

Yes, it matches the same DDR4 2400 speed, CL17 latency and 1.20V voltage, so it can operate alongside identical-spec modules in a multi-channel configuration.

How do I confirm the module is recognised as 16GB ECC registered memory after installation?

Check the system BIOS or OS memory report; it should show 16GB, DDR4 2400, ECC RDIMM, 1Rx4 organisation and 1.20V operation.

Does the single 288-pin DIMM ship alone, or are brackets and cables included?

Only the 16GB DDR4 2400 ECC RDIMM module is supplied; no brackets, cables or additional hardware are included.
