How Do I Know How Much Ram My Laptop Can Support

[Evheniyyy]

i am looking at upgrading the ram in my laptop but can not find the system specification on how much it can use?

now i wanna know if i can upgrade my laptop to 32gb of ram, where i can check a max capacity of ram for my laptop?

also i wanna know how much MHz my ram should have? now i have ram with 2666MHz, can i use higher values or this value that i have is max for my laptop?

Help please!

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

However, in the past few years HP usually understates how much memory the notebook can support.

Maybe that is just how much memory they tested in the notebook, since there is usually no need to install more memory than that.

Another thing you can do is to run this command to see what Windows indicates 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. After the command prompt has opened, type wmic memphysical get maxcapacityEx and press the enter key.

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.

You can install DDR4-3200 MHz memory in your notebook, but it will automatically bridge to 2666 MHz because that is as fast as your notebook's processor can run the memory at.

Thanks for reply!
You said "Maybe that is just how much memory they tested in the notebook, since there is usually no need to install more memory than that." You mean that there is no need for me to install 32gb of ram for my laptop? Because i run the command in cmd and get result on the screen ->

so after dividing it is 32
therefore in my case better to upgrade my laptop with 32gb of ram, correctly i understand? and in result everything should work without any problems?

The RAM as (Kingston Fury SODIMM DDR4-2666 16384MB PC4-21300 (two this items)) is compatible with my laptop, correctly i understand?

You're very welcome.

There usually isn't a need to install more than 16 GB of memory but everyone's situation can be different.

Other than just saying 'I want to install all of the memory my PC can handle, which of course is your privilege, I suggest you take an objective approach to deciding if it is really necessary.

Run the Windows Resource Monitor app.

Then click on the memory tab.

Look at how much free memory your notebook has available for use.

If the free memory amount is more than 50% of the total, then you will probably not derive much benefit adding more memory.

But if money is no object and you don't care how much free memory your notebook has available, by all means, max out the memory to 2 x 16 GB.

Make sure any memory you buy has the standard timing specs for the memory speed.

Your notebook uses DDR4-2666 MHz CL19 memory.

Faster timing memory than that will probably not work because if the BIOS can't automatically adjust to the faster timing speed, there is no way to go into the BIOS and make any memory speed/timing adjustments.

If you choose to install DDR4-3200 memory, that needs to have a CL22 speed which will automatically bridge to 2666 MHz, CL19.

I am so sorry for confusing, but i have again some questions...

I want to pick a ram with 16gb 2666MHz, Now i use also this value of memory frequency with CL-19 timing memory.
but market in specs write for 16gb 2666MHz, timing memory value as CL15-17-17. Does this ram suit for my laptop, explain me please!

[Paul_Tikkanen]

You can only use DDR4-2666 CL19 memory.

CL15 memory is almost guaranteed not to work.

[Evheniyyy]

Ok, I see, thanks for your explanations!

[Paul_Tikkanen]

Anytime.

Glad to have been of assistance.

I am so sorry again, but can you help me with explanation one more time please)
I want to buy Kingston Fury ram but this rams in specs don't have CL19, I found the most closer that is CL16-18-18
also i check some specifications of my laptop (on screens)

here there is different CLs (like 17-18-19-20)
so if i choose the ram that has CL16-18-18, then may in this case everything work without any issues?

or anyway better to choose ram that has only CL19 for highest performance and compatability?
Thank you in advance for your response!!!

That memory won't work  

Look into buying DDR4-3200 CL22 memory  

It doesn't have to be performance or gaming memory.
