Compatible HP OMEN DDR5 Upgrade

This 8GB DDR5 5200 CL42 UDIMM module is built for HP OMEN 40L GT21-2100t and 45L GT22 desktops. It delivers a JEDEC-standard memory upgrade that installs without configuration changes. The single-rank 1Rx8 design runs at 1.1V for efficient operation.

Who Should Add This Module

Owners of the listed OMEN systems who need a straightforward capacity increase will benefit. Builders requiring ECC error correction, registered DIMMs, or speeds beyond 5200 MT/s should look at other memory types. Systems outside the validated HP OMEN range are not guaranteed compatible.

8GB Capacity For Everyday Workloads

Eight gigabytes handles web browsing, office suites and light multitasking comfortably. Demanding content creation, virtualisation or modern gaming with large texture packs will exceed this single module's headroom. Adding a second identical stick doubles capacity and enables dual-channel bandwidth.

Questions about this item

Will this single 8 GB DDR5-5200 CL42 UDIMM work in my HP OMEN 40L GT21-2100t that currently has only one memory module installed?

Yes — the module is a 288-pin 1.1 V unbuffered DDR5 DIMM validated for the OMEN 40L GT21-2100t, so it will function as a standalone upgrade or alongside an identical stick.

Can I add this 5200 MT/s CL42 stick to an OMEN 45L GT22-1000m that already has factory DDR5 memory?

The system will run all modules at the speed of the slowest installed kit; this OWC part is JEDEC-standard DDR5-5200 CL42, so it will operate correctly at the common frequency.

How can I confirm the new 8 GB module is recognised at DDR5-5200 CL42 after installation?

Open Task Manager → Performance → Memory or run CPU-Z; both will show 5200 MT/s, CL42 timings, 1.1 V and 8 GB capacity for the OWC DIMM.
