HP Omen X 900 upgrade

This 16 GB DDR4 module is built specifically for HP Omen X 900 desktops including the 900-250ng, 900-251ng, 900-280nz, 900-284nz and 900-290 models. It runs at 2666 MHz with CL19 timing at 1.2 V. The unbuffered, non-ECC UDIMM fits the standard 288-pin desktop slot.

Installation experience

The stick drops into a regular DIMM socket and locks with the side clips — no tools required. Because it is unbuffered and non-ECC, the firmware usually recognises it at 2133 MHz or 2400 MHz until XMP or manual timing is set. A common issue is forgetting to seat both ends evenly, which causes a no-post condition.

Suitability guide

Ideal for owners of the listed Omen X 900 systems who want a straightforward capacity increase. Builders using other motherboards, anyone needing ECC or registered memory, or users who require speeds above 2666 MHz should look at something else.
