HP 32GB (1x32GB) DDR5-4800

32GB (1x32GB)DDR5-4800JEDEC plug-and-playDDR5 UDIMM

The HP 4M9Y2AA is a 32GB (1x32GB) DDR5-4800 desktop memory module for HP business desktops of the G9 generation (Pro 400, Elite 600/800) and the Z2 G9 workstation. It is a single 32GB module.

It runs at its rated setting, stored in its SPD (DDR5-4800 (JEDEC)), with no BIOS changes. It is HP’s own option part for these systems, so the BIOS recognises it as HP memory and it carries HP support.

Before you order: This is non-ECC unbuffered DDR5. HP Z2 G9 workstations configured with ECC memory need ECC UDIMMs instead — do not mix ECC and non-ECC modules in one system.

What It Means in Practice

  • Adding a second identical 32GB module enables dual channel and 64GB total — on these desktops that roughly doubles memory bandwidth versus a single module.
  • Runs at DDR5-4800, the speed HP specifies for these platforms; no BIOS changes are required.
  • Ideal for upgrading office or engineering desktops that shipped with 8GB or 16GB and now run large spreadsheets, CAD viewers or many browser tabs.
  • For the best result install modules in matching pairs; mixing with the factory 8GB/16GB modules works but may run in flex mode.

What Will Not Work

  • Laptops and HP Mini/Elite Mini desktops that use SO-DIMM slots.
  • DDR4 HP desktops (G8 generation and earlier) — DDR5 does not fit DDR4 slots.
  • Z2 G9 or other workstations running ECC memory — this module is non-ECC.
  • Overclocking — there is no XMP/EXPO profile; it runs at the JEDEC 4800 MT/s only.

Frequently Asked Questions

Will a non-HP module work just as well?
A standard DDR5-4800 UDIMM usually works, but the HP part is the one HP lists for these systems and supports under its warranty terms — useful for managed corporate fleets.
How many can I install?
These desktops have up to four DIMM slots (depending on model and form factor); check your model’s maximum memory before ordering more than two.
Singular Expert Insight · Buyer's Guide
For HP G9 business desktops the simplest upgrade is two identical 32GB modules for 64GB in dual channel. Check the exact model on the service tag and confirm whether a Z2 G9 runs ECC memory before ordering. Browse our memory range for other HP-compatible memory.
✓ Buy it if you are upgrading an HP Pro 400 G9, Elite 600/800 G9 or non-ECC Z2 G9 desktop.
✕ Skip it if your HP uses SO-DIMM, DDR4 or ECC memory.
→ Also consider A second 4M9Y2AA for 64GB in dual channel.
