Understanding these metrics helps diagnose performance issues related to memory usage.

What should I do if Windows 11 reports less RAM than I physically installed?

If Windows 11 reports less RAM than you physically installed, there are a few possible causes. Firstly, check if you are running a 32-bit version of Windows. 32-bit versions of Windows can only address a maximum of 4GB of RAM. If you have more than 4GB installed, you need to upgrade to a 64-bit version of Windows to utilize it fully.

Secondly, verify that all your RAM modules are properly seated in their slots. Power off your computer, open the case, and ensure each RAM stick is firmly and correctly installed. A loose connection can prevent the system from recognizing the full amount of RAM. Also, check your BIOS/UEFI settings. Sometimes, the BIOS may have a setting that limits the amount of usable RAM. Look for memory-related settings and ensure they are configured correctly to recognize all installed RAM.
