16GB DDR4 2933MHz ECC RDIMM

This 16GB registered DIMM runs at DDR4 2933MHz with CL21 latency and 1.20V operation. It targets server and workstation administrators who need error-correcting memory for data integrity. The single-module design suits upgrades or fresh deployments where ECC RDIMM support is required.

288-pin registered DIMM fit

The module uses the standard 288-pin DDR4 RDIMM form factor and registered buffering to reduce electrical load on the memory controller. It requires a platform that supports DDR4 2933MHz ECC registered memory and an available DIMM slot. The single rank 2Rx8 organisation leaves additional slots free for further capacity expansion.

Replaces HP P00922-B21 and listed part numbers

This unit serves as a direct replacement for the HP part numbers P00922-B21, P03050-091, P03050-191, P03050-C91, P06188-001, P18449-B21, P19042-H21 and P19255-001. The upgrade is worth it when existing modules have failed, when capacity must grow beyond current limits, or when a qualified ECC RDIMM is needed to maintain warranty compliance.

Questions sur cet article

Does the CL21 latency become a bottleneck under sustained server workloads?

CL21 is the rated CAS latency for this DDR4 2933 module; actual throughput under sustained load depends on the server memory controller and DIMM population rules.

What are the thermal and power characteristics when this RDIMM runs continuously at 1.20 V?

The module operates at the standard DDR4 1.20 V; registered DIMMs add minimal register power, and no active cooling is required beyond normal server airflow.

Which HP server part numbers confirm that this 288-pin ECC RDIMM will work in my system?

This 16 GB DDR4 2933 2Rx8 module is a compatible replacement for HP P00922-B21, P03050-091, P03050-191, P03050-C91, P06188-001, P18449-B21, P19042-H21, P19255-001.
