Run the free utility that I zipped up and attached below to see what speed memory HP installed in your notebook.
Your notebook's processor runs the memory at the max speed of 2400 MHz, but they may have installed a 2666 MHz memory chip in your notebook.
Buy the memory module that matches the speed of the memory HP installed...2400 or 2666 MHz.

Glad to have been of assistance.
The memory should work just fine with the existing module.
Please post back and let us know how your notebook's memory upgrade project went.
