32GB DDR4 2400 ECC RDIMM

This 32GB DDR4 2400 ECC RDIMM module targets server and workstation operators who need registered memory with error correction for stable, high-capacity configurations. It runs at PC4-19200 speed with CL17 latency and 1.20V voltage.

Replaces HP 852265-001 and 819412-001

The module serves as a direct replacement for HP part numbers including 852265-001, 819412-001, 809083-591, 809083-EF1, 809083-09S, 855507-091, 805351-K21, 862932-B21, T9V41AA and 875351-B21. The upgrade is worth it when your system requires registered ECC DIMMs and the current memory limits workload capacity.

288-pin DIMM installs in standard slots

Installation follows the usual 288-pin DIMM procedure: align the notch, press firmly until the latches click, and verify seating. What usually goes wrong is mixing registered and unbuffered modules or exceeding the platform's rank and population limits, so confirm the supported memory specifications before adding this 2Rx4 stick.

Questions about this item

Will the 288-pin DDR4 DIMM fit my HP server memory slot?

This module uses the standard 288-pin DDR4 DIMM form factor, matching the slot used by HP part numbers such as 852265-001 and 819412-001.

Do I need to install the registered ECC module in a specific slot order?

Install the RDIMM in the slot sequence recommended by your server's service guide; the common error is populating slots out of order, which prevents the system from initialising the registered buffer.

How can I tell if the 2Rx4 rank organisation is still healthy years later?

Run the server's built-in memory diagnostics or a tool like MemTest86 periodically; ECC corrects single-bit errors silently, so a rising corrected-error count in the system logs signals the module may need replacement.
