HP OMEN DDR5 Upgrade

This 16GB DDR5 module is built for HP OMEN 25L, 40L and 45L desktops listed in the compatibility data. It targets owners of those systems who want a straightforward memory increase for heavier multitasking or larger workloads.

Compatibility Check

Verify that your HP OMEN model matches one of the five exact model numbers shown in the specifications before ordering. Confirm the motherboard has a free 288-pin DDR5 UDIMM slot and that the system BIOS recognises 5200 MHz non-ECC unbuffered memory.

Thermals and Power

The module runs at the standard JEDEC voltage of 1.1V and carries no heat spreader, so it relies on case airflow for cooling. Power draw is low for a single 16GB stick and the unbuffered design adds no active components that would increase noise.

Questions about this item

Does the 16GB DDR5 5200 CL42 module ship alone, or do I need to buy anything else for my HP OMEN 25L GT15-1075t?

The upgrade consists of a single 16GB DDR5 5200 CL42 1Rx8 UDIMM. No extra parts are required; it installs directly into an available 288-pin slot on the listed OMEN desktops.

My HP OMEN 40L GT21-1490xt has four slots — should I add one 16GB stick or two for dual-channel?

Adding one 16GB module increases total capacity. For dual-channel bandwidth, install a second identical 16GB stick in the matching slot; the board will then run both at 5200 MT/s CL42.

Will the PC5-41600 5200MHz rating actually run at that speed inside an OMEN 45L GT22-1455xt, or does it downclock?

The module is JEDEC-standard DDR5-5200 CL42 at 1.1V. The OMEN 45L GT22-1455xt memory controller will configure it at 5200 MT/s automatically, provided the BIOS is current.
