Windows 7: 4GB RAM in place, but only 2GB showing in BIOS

Windows 7 Ultimate x64

My ram sticks are identical, in both slots, serials and all, I inspected it myself. You can trust Speccy haha :)

Speccy is doing the job it was designed to do. It tells us of the existence and characteristics of the memory modules, nothing more. It tells us nothing of it's accessibility by Windows, it's compatibility with the system or with other modules, or even that it is functioning. Only that it is there and able to be identified. The same for other utilities of it's type.

Speccy doesn't test the memory because it can't. A meaningful test of memory from within Windows is virtually impossible. At bootup the BIOS is able to do a memory test and this is done to the extent necessary to identify memory that is accessible and functional, but not necessarily that it is reliable.

Speccy is a useful utility but don't expect to be something it is not.

Windows 10 Pro. 64/ version 1709 Windows 7 Pro/64

Speccy does the job it's designed to do. No more no less.
I would still like to see the picture of Resource Monitor/memory as I requested in post #7.

This tutorial by Brink should help.
