HPE-Compatible DDR4 ECC RDIMM

This 16GB registered DIMM is built for HPE servers and workstations that require DDR4 2933 memory with error correction. The module carries the PC4-23400 rating and a CL21 latency profile suited to enterprise workloads. It targets administrators upgrading compatible HPE platforms such as the P00920 family.

288-pin registered form factor

The stick uses a standard 288-pin DDR4 RDIMM edge connector and a single-rank 1Rx4 organisation based on major OEM DRAM. No heat spreader is fitted, so clearance inside dense chassis is maximised. Installation follows the usual DIMM-slot procedure; consult the system manual for population rules.

1.20V operation with ECC integrity

Running at 1.20V, the module draws minimal power while ECC circuitry corrects single-bit errors in real time. Registered buffering reduces electrical load on the memory controller, aiding signal integrity in multi-DIMM configurations. Typical server airflow keeps temperatures in check without active cooling on the module itself.

Questions about this item

Does the DDR4 2933 PC4-23400 interface cap speed at 2933 MT/s in HPE servers?

Yes, the DDR4 2933 PC4-23400 standard runs at 2933 MT/s; the module will operate at that speed or downclock to the platform's supported rate.

What physical slot and clearance does the 288-pin 1Rx4 RDIMM need to fit?

It requires a standard 288-pin DDR4 RDIMM slot; the module has no heat spreader, so it fits low-profile DIMM bays in HPE servers.

How is the ECC registered module installed, and what step is often missed?

Power down, open the chassis, align the key notch with the slot ridge, press firmly until both latches click, then enable ECC in the BIOS/UEFI — skipping the BIOS step leaves error correction inactive.
