System-Specific DDR5 Kit for HP OMEN 40L and 45L

This OWC kit supplies 16GB of DDR5 memory in a matched pair of 8GB modules. It is built for HP OMEN 40L GT21-2100t and 45L GT22-1000m, GT22-1470se and GT22-2000t desktops. The modules are unbuffered, non-ECC UDIMMs that run at the standard 1.1V.

Upgrading from Slower or Smaller Factory Memory

The kit replaces the original DDR5 DIMMs fitted by HP at 5200 MT/s with CL42 latency. The jump is worth it when the system shipped with less than 16GB total capacity or when the factory modules run at a lower JEDEC speed grade. The 1Rx8 organisation keeps electrical loading low on the memory controller.

Limits of the DDR5 5200 JEDEC Standard

The PC5-41600 rating sets the maximum data rate at 5200 MT/s and the timing at CL42 under JEDEC specifications. Voltage is fixed at 1.1V with no XMP or EXPO profiles available on these modules. Builders who need higher frequencies or tighter latencies must choose a different memory standard.

Questions about this item

Will the 288-pin DDR5 UDIMMs fit the HP OMEN 40L and 45L desktop slots?

Yes, the kit uses standard 288-pin DDR5 UDIMM form factor, which matches the memory slots on HP OMEN 40L GT21-2100t, 45L GT22-1000m, 45L GT22-1470se and 45L GT22-2000t systems.

How do I install the two 8GB modules, and what step do people often miss?

Power off and unplug the PC, open the case, align each module's notch with the slot key, press firmly until both side clips click, then enter BIOS to confirm the system sees 16 GB at 5200 MT/s.

When will this memory need replacement or maintenance?

DDR5 modules have no moving parts and require no routine maintenance; they typically last the life of the system unless a fault occurs, in which case OWC provides a limited lifetime warranty with advanced replacement.
