HP OMEN X laptop upgrade

This 4GB DDR4 SODIMM is built for HP OMEN X 17-ap000na, 17-ap000nb, 17-ap000nd, 17-ap000nf and 17-ap000ng notebooks. It targets owners of those models who need a straightforward memory increase. The module is validated for that specific platform. Buyers with other laptops or desktop boards cannot use this part.

Build and installation

The stick uses a standard 260-pin DDR4 SODIMM edge connector and runs at 1.2V without a heat spreader. Its low-profile design fits tight laptop slots and requires no extra clearance. Installation is a typical DIY task: open the access panel, insert the module until it clicks, then close the case. No tools beyond a small screwdriver are needed.

Speed and timing spec

The memory operates at DDR4 2400 (PC4-19200) with CL17 latency and 1Rx8 organisation. This single rating determines whether the module matches the system's supported speed grade. If the laptop requires a different frequency or latency the upgrade will not work as intended.
