Hi, @boooble 

 

Generally, since you can't make any memory timing adjustments in your notebook's BIOS, it is best to buy memory that has the standard timing speeds for the memory speed.

 

KF426S16IBK2_32 (kingston.com)

 

As you can see from the timing specs, the Kingston gaming memory's timing is  CL 16-18-18

 

A standard DDR4-2666 MHz memory bar will have timing specs of CL 19-19-19

 

Your notebook has standard DDR4-2400 memory with CL 17-17-17 timing specs.

 

Your notebook's  i7-7700HQ processor can only run the memory at a max speed of 2400 MHz, so a standard DDR4-2666 memory bar will work fine, but only at 2400 MHz, and the timing will adjust to CL17.

 

I recommend that you play it safe and buy standard timing DDR4-2400 or DDR4-2666 MHz memory.

 

I believe your notebook will support 2 x 16 GB of memory, but both chapter 1 of the service manual and the crucial memory report indicate the max is 2 x 8 GB.

I also suggest you do the following to determine 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 maxcapacity 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.

Its specs

 

         https://support.hp.com/au-en/document/c05609719

 

It has  12 GB DDR4-2400 SDRAM (1 x 4 GB, 1 x 8 GB) now, you can upgrade to 16GB by remove its 4GB and add same existing 8GB to it.

 

You can install 2666MHz RAM but machine won't run at 2666MHz.

 

My opinion: its has 12GB now and move to 16GB (max) is not a good move.

 

Regards.

Thank you for quick and extended answer. By the way I checked in the command prompt and after I divided I got 32. Thanks again.
