Hi:

The fastest speed your PC's Intel® Core™ i5 9400T processor can run the memory at is 2666 MHz.

Intel Core i59400T Processor 9M Cache up to 3.40 GHz Product Specifications

You can do this to see how much memory your PC can actually 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.

hi

I answered you here..
we tell you that you can install 32 gb!
off the hp info only says 16gb
In some cases, it is possible to install more, but under certain conditions!
So here, either you don't have the necessary modules, or you have to check if a bios update can correct this, or the motherboard does not allow it!

• Dual channel memory architecture
• Two DDR4 SODIMM (260-pin) sockets
• Supports up to PC4-19200 (DDR4-2400)
• Supports 2 GB, 4 GB, and 8 GB DDR4 SODIMMs
• Supports up to 4 GB on 32-bit systems

  note:

  32-bit systems cannot address a full 4.0 GB of memory.

• Supports up to 16 GB (unbuffered) with 8 GB DIMMs on 64-bit systems

crucial therefore in general possibilities of compatible modules
but sometimes it is wrong!
it may be possible to use a module other than what is shown for the DDR4-2400 motherboard here
sometimes it will work at the possible frequency of the motherboard, sometimes not at all

your amazon link, we don't know if it's the same model, same series, not conclusive here

do you think this will work 

There is a newer model of this item: Crucial RAM 32GB Kit (2x16GB) DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Laptop Memory CT2K16G4SFRA32A

and thank you for the help

You're very welcome.

Yes, the DDR4-3200 memory should work fine but it will only run at 2666 MHz.
