HPE-Compatible 64 GB DDR4-2666 Registered ECC

This module is a 64 GB DDR4-2666 registered DIMM with ECC and a 2Rx4 organisation. It operates at 1.20 V and uses the standard 288-pin form factor for server platforms. The part is validated as 100 percent compatible with the HPE P05592-H21 specification.

Suited for HPE server upgrades needing matched 64

It fits administrators who must keep factory warranty coverage while expanding memory capacity with identical modules. Buyers who need unbuffered UDIMMs, lower-density DIMMs, or non-ECC memory for workstation or desktop boards should look elsewhere.

Registered 2Rx4 ECC at DDR4-2666 and 1.20 V

The registered 2Rx4 ECC design is the single attribute that determines whether the module will post in a given HPE server slot. Verify that the target platform requires registered ECC DDR4-2666 before ordering.

Questions about this item

What speed does the PC4-21300 rating cap this DDR4 module at in practice?

The PC4-21300 rating means the module runs at DDR4 2666, which is the maximum data rate the JEDEC standard defines for this speed grade.

What physical slot and pin count does this 288-pin registered DIMM need to fit?

It requires a standard DDR4 288-pin RDIMM slot; the registered design adds a buffer chip so it only fits server or workstation boards that support registered memory.

How is this HPE-compatible module installed, and what step do people often get wrong?

Align the notch with the slot key, press straight down until both side clips click, and verify the system detects the full 64 GB — skipping the clip check is the common mistake.
