HP OMEN 45L GT22-2085t Upgrade

This OWC module is an 8GB DDR5 5200 UDIMM built for the HP OMEN 45L GT22-2085t desktop. It runs at 1.1V with CL42 latency in a single-rank 1Rx8 configuration. The 288-pin unbuffered non-ECC design matches the system's memory slots for a direct fit.

Replacing Slower DDR5 Modules

The upgrade replaces any lower-speed DDR5 memory currently installed in the OMEN 45L GT22-2085t. The jump is worth it when the existing memory runs below 5200 MT/s or when total capacity limits multitasking. JEDEC compliance ensures the new module operates at the platform's rated specification without manual tuning.

Builders Expanding OMEN 45L Memory

This single 8GB stick suits owners adding capacity to a free slot or matching an identical module for dual-channel operation. Buyers who want more storage capacity or require ECC error correction should look at something else, as this kit provides neither. Systems outside the OMEN 45L GT22-2085t are not validated for this part.
