HPE 32GB DDR4-2666 Registered DIMM

This HPE server memory module provides 32GB of DDR4 capacity in a single DIMM. It operates at 2666MT/s to the PC4-21300 standard with registered signal processing. The part is manufactured by Hewlett Packard Enterprise under part number 850881-001.

Suited for HPE servers requiring registered ECC

This module fits systems that accept registered DDR4 DIMMs with ECC support. It is not for desktop or laptop motherboards that use unbuffered memory. Builders needing unregistered SODIMMs or non-ECC UDIMMs should look at something else.

32GB per module at DDR4-2666

Each stick delivers 32GB of capacity at 2666MT/s. The registered design and ECC function are the defining specifications for platform compatibility. Verify that your server board supports registered DDR4 DIMMs before purchase.

Questions about this item

What form factor does the 850881-001 module use for server slots?

The module uses the standard DIMM form factor so it fits any server slot that accepts registered DDR4 DIMMs.

How is the registered DDR4 DIMM installed and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module is fully seated by checking both ends are level.

When should the 32GB DDR4-2666 ECC module be replaced in a production server?

Replace the module if the system logs report correctable ECC errors that exceed the platform threshold or if diagnostics flag a persistent fault on this DIMM.
