Probook 640 G4 i7-8850H maximum RAM support

[ConorMaclaud]

I found in different resources different information about maximum RAM support, is it 32 or 64 GB for Probook 640 G4 i7-8850H?

Thanks

Run this command to confirm...I believe it is 2 x 16 GB:

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 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.

Chapter 1 of the service manual indicates the max memory is 32 GB:
