HP OMEN 45L Memory Upgrade Kit

This OWC kit adds 16GB of DDR5 memory to the HP OMEN 45L GT22-2085t using two 8GB unbuffered UDIMM modules. Each stick runs at 5200MHz with a CL42 latency at the standard 1.1V JEDEC voltage. The 288-pin non-ECC design matches the factory specification for a warranty-safe installation.

Builders With Compatible OMEN Desktops

Owners of the HP OMEN 45L GT22-2085t who need more capacity for multitasking or larger files will find this kit a direct fit. Systems that require ECC registered modules, a different DDR generation, or a higher voltage cannot use these sticks. Buyers with other motherboards should verify their exact memory requirements first.

16GB Dual-Channel Capacity Decides Fit

The 16GB total capacity provided by the matched pair determines whether this upgrade meets the user's workload demands. Two 8GB modules populate two slots for dual-channel operation on the supported platform. If the target application needs more memory than this kit supplies, a larger capacity kit must be sourced instead.

Questions about this item

Will these 288-pin DDR5 modules fit the HP OMEN 45L GT22-2085t motherboard slots?

Yes, the kit is built as a 288-pin DDR5 UDIMM upgrade specifically validated for the HP OMEN 45L GT22-2085t desktop.

What is the correct way to seat the two 8GB sticks so the system recognises the full 16GB?

Power off, open the case, align each module notch with the slot key, press firmly until both side latches click, then boot to confirm 16GB detected.

Do these non-ECC DDR5 sticks need any firmware updates or periodic reseating over time?

No firmware is required; the JEDEC-standard modules run at 1.1V and are designed to remain seated for the life of the system.
