Hi:

Chapter 1 of the service manual indicates the max memory is 2 x 8 GB.

Maintenance and Service Guide (hp.com)

The Crucial memory report indicates your notebook could support 2 x 32 GB of memory.

The only suggestion I can offer would be to do this to see how much memory your notebook can support:

1. In the search box, search for cmd and click Run as administrator.

This will open the command prompt.

2. Once command prompt is opened, type wmic memphysical get maxcapacityEx and hit enter.

There, it will show the maximum RAM capacity your PC's motherboard can support.

The capacity is shown as Kilobytes, so you have to convert it to Gigabytes by dividing the number provided in the report by 1,048,576.

This would be the compatible 16 GB memory chip for your notebook:

Bear in mind that if you install a 16 GB + a 4 GB memory chip in your notebook, the memory will run in single channel mode.

In order for the memory to run in dual channel mode, it has to be installed in matching capacities.
