What is the maximal amount of RAM possible on 15-gw0030ur?

[SSCL]

I'm willing to upgrade RAM on my 15-gw0030ur (stock 2×4GB aren't really enough, especially as its hybrid graphics consume 2GB of system RAM) and I can't find what's the maximum volume the hardware supports, in total and per each bank.

Could someone please help me finding it out?

Hi:

Below is the link to the service manual for your notebook.

Maintenance and Service Guide (hp.com)

Chapter 1 has the memory upgrade information.

Your notebook has two memory slots and officially supports 2 x 8 GB of DDR4-3200 memory.

The notebook probably supports 2 x 16 GB of memory.

You can do this to see how much memory the notebook 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, and thank you for your prompt answer!

The link you provided doesn't work for me for some reason.

Turns out, one can actually read (from DMI data, I guess?) how much RAM their hardware supports.

In my case it is 64GB across two banks:

sudo dmidecode -t 16

Handle 0x0020, DMI type 16, 23 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 64 GB
Error Information Handle: 0x0023
Number Of Devices: 2

I used dmidecode utility; I don't use MS Windows on this laptop.

And thanks again!
