Who It's For

This memory module is best for owners of the listed HP Spectre x360 and Pavilion 15 models who need to bring a system up to 16GB for smoother multitasking, improved browser performance, and lighter media editing tasks. It is also a good choice for people replacing a failed module with a compatible spec without changing the laptop's configuration.

It is not targeted at users who need server-grade stability or ECC memory, high-end gaming rigs that require very low-latency overclocking parts, or systems that do not accept DDR4 2666 MHz SODIMM modules. Buyers should check their exact HP model number against the compatibility list before purchase.
