OWC 16GB DDR5 5200 UDIMM for OMEN 40L 45L

This OWC 16GB DDR5 5200 CL42 1Rx8 1.1V UDIMM is a non-ECC unbuffered module built to JEDEC PC5-41600 specifications. It targets owners of HP OMEN 40L GT21-2100t and 45L GT22-1000m, GT22-1470se and GT22-2000t desktops who want a single-stick capacity increase for multitasking and larger workloads.

Verify 288-pin DDR5 slot

Before ordering confirm your system uses 288-pin DDR5 UDIMM slots and accepts 1.1V modules. The board must run PC5-41600 speed and CL42 timing without requiring ECC or registered memory. Check the current population to ensure an empty slot exists for this 1Rx8 stick.

Single 16GB stick adds capacity without paired-kit

The bundle is a single 16GB module so you can populate one free slot instead of buying a matched pair. No heat spreader is included which keeps the profile low for tight OMEN chassis clearance. The JEDEC and ROHS compliance makes the upgrade warranty-safe for the listed models.
