HP OMEN X 900-290nf 900-290nz 900-299nd Upgrade

This OWC 16GB DDR4 2666MHz CL19 1.2V 288-Pin UDIMM is built for the HP OMEN X 900-290nf, 900-290nz and 900-299nd desktops. It adds a single 16GB module to increase total system memory for multitasking and larger workloads. The non-ECC unbuffered design matches the original specification. Buyers who need ECC or registered memory for server platforms cannot use this module.

DDR4 2666MHz PC4-21300 CL19 Constraints

The module runs at DDR4 2666MHz with PC4-21300 bandwidth and CL19 latency at 1.2V. It is backward compatible with 2133MHz and 2400MHz systems, where it will operate at the lower speed. Systems limited to speeds below 2133MHz or requiring a different voltage will not support this memory. The 288-pin UDIMM form factor fits standard desktop DIMM slots only.

Replaces Slower DDR4 or Smaller Capacity Kits

This kit upgrades from 2133MHz or 2400MHz DDR4 by raising the memory clock to 2666MHz while maintaining JEDEC compliance. It also replaces smaller 8GB modules to double per-slot capacity to 16GB. The jump is worth it when the platform supports 2666MHz and the workload benefits from higher bandwidth or greater total memory.

Questions about this item

Is this 16GB module the right capacity for my HP OMEN X 900-290nf?

This single 16GB DDR4 2666MHz CL19 UDIMM is validated for the HP OMEN X 900-290nf, 900-290nz and 900-299nd. It installs in any free 288-pin slot and adds 16GB of non-ECC unbuffered memory at 1.2V.

What does the 2666MHz rating deliver once installed in my OMEN X desktop?

The module runs at DDR4 2666MHz (PC4-21300) with CL19 latency. If your system currently uses 2133MHz or 2400MHz memory, this stick will operate at the highest common speed supported by the platform, improving bandwidth for multitasking and large files.

Does the PC4-21300 designation limit the speed on my motherboard?

PC4-21300 is the JEDEC standard name for DDR4 2666MHz. The module is backward compatible with 2133MHz and 2400MHz systems, so it will run at the fastest speed the memory controller allows without manual configuration.
