Hi:

Chapter 1 of your notebook's service manual indicates it can support up to 2 x 8 GB of memory.

Maintenance and Service Guide HP 15 Laptop PC

The Crucial memory report for your notebook's model series indicates that it can support up to 2 x 16 GB of memory.

HP - Compaq HP 15-ef0xxx Models | Memory RAM & SSD Upgrades | Crucial.com

You can 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.

In addition to the service manual, here is a service teardown video for the model series:
