Compatible HP OMEN Desktops

This 16 GB DDR5 kit is validated for HP OMEN 25L, 40L and 45L desktops including models GT15-1075t, GT15-2085t, GT21-1490xt, GT21-2085t and GT22-1455xt. The two 8 GB unbuffered non-ECC modules install directly into the standard 288-pin DIMM slots.

Sustained Load Behaviour

JEDEC-standard DDR5-5200 operation at 1.1 V keeps power draw and thermals predictable during extended workloads. CL42 latency and 1Rx8 organisation deliver consistent bandwidth without relying on overclocking headroom.

DDR5 Platform Limits

The PC5-41600 rating defines the maximum guaranteed transfer rate for this memory class. Systems that do not support DDR5 5200 will downclock the kit to the highest mutually supported speed.

Questions about this item

How much power does the 1.1 V DDR5 kit draw during all-day operation?

The modules run at 1.1 V, the standard JEDEC voltage for DDR5, so power draw stays within the platform's default memory budget without extra cooling.

What must the HP OMEN desktop already have to accept this 288-pin UDIMM kit?

The system needs free 288-pin DDR5 UDIMM slots and a BIOS that supports PC5-41600 CL42 memory; the listed OMEN 25L, 40L and 45L models meet those requirements.

Will the CL42 sticks work alongside any original DDR5 memory left in the OMEN?

Yes, JEDEC-standard DDR5 at 5200 MT/s CL42 will run at the lowest common speed and latency when mixed with the factory modules.
