HP OMEN X 900 compatible DDR4 UDIMM

This 8GB DDR4 2666MHz CL19 module is built specifically for HP OMEN X 900-290nf, 900-290nz and 900-299nd desktops. It suits owners of those systems who want a straightforward capacity increase. Buyers with other motherboards or laptops should verify their exact memory requirements before purchasing.

DDR4 2666MHz JEDEC standard limits

The module runs at the standard 1.2V JEDEC voltage with CL19 timings and will down-clock to 2400MHz or 2133MHz if the platform demands it. It does not support XMP profiles, ECC error correction or registered buffering. Systems requiring registered DIMMs or higher factory speeds cannot use this stick.

Simple DIY installation with common pitfalls

Installation follows the usual UDIMM procedure: power off, open the case, align the notch and press until the clips latch. The most frequent issues are mixing speeds across channels, leaving a slot unpopulated in a dual-channel board, or forgetting to seat the module fully so the system fails to POST.

Questions about this item

Should I pick the 8 GB module or add a second stick for dual-channel?

The module is a single 8 GB stick. Adding a second identical module enables dual-channel bandwidth on the OMEN X 900-290nf, 900-290nz and 900-299nd platforms.

What does the 2666 MHz rating deliver inside my OMEN X 900-290nf?

The memory runs at 2666 MHz with CL19 timing at 1.2 V. If the system BIOS only supports 2133 MHz or 2400 MHz, the stick will down-clock automatically to match.

Is the 288-pin DDR4 UDIMM interface the limiting factor for speed?

The 288-pin unbuffered DDR4 form factor carries the PC4-21300 signal. The practical ceiling is the 2666 MHz JEDEC rating; the slot itself does not impose a lower limit.
