32 GB DDR4-3200 Registered ECC Module

This 32 GB DDR4-3200 registered ECC RDIMM is built for HP server platforms that require error-correcting, buffered memory. The 1Rx4 organisation and PC4-25600 rating suit workloads that demand data integrity and high capacity per slot.

Installation requires compatible registered DIMM

The module installs like any standard RDIMM but will not function in systems that only accept unbuffered UDIMMs or lack ECC support. Mixing registered and unbuffered DIMMs, or populating slots in an order the platform firmware does not expect, are the most common reasons the memory is not recognised.

Sustained operation at 1.20 V with ECC active

Under continuous load the registered buffer reduces electrical loading on the memory controller while ECC corrects single-bit errors in real time. This combination maintains data integrity during long-running compute or virtualisation tasks without the error accumulation seen on non-ECC modules.

Questions about this item

How can I confirm the module is running at the rated 3200 MT/s after installation?

Enter the server BIOS or UEFI and check the memory speed field; it should show 3200 MT/s (PC4-25600) with the registered ECC module detected at 1.20 V.

What ships with the P56427-B21 module and what must I source separately?

The box contains the single 32 GB 1Rx4 DDR4 RDIMM only; no heatsinks, cables or additional DIMMs are included.

Which capacity and rank variant should I pick for a dual-channel server board?

Choose this 32 GB 1Rx4 registered ECC stick; it provides one rank per channel and matches the HP P56427-B21 specification.
