Windows 10 shows installed memory in Settings, while Task Manager provides more detail about how much RAM is being used. These built-in tools are usually enough to check memory without installing hardware-information software.
Check installed RAM in Settings
- Open Settings.
- Select System.
- Choose About.
- Look for Installed RAM under Device specifications.
Check current memory use
Press Ctrl + Shift + Esc, open Performance, and select Memory. Task Manager shows current usage and additional information such as speed and hardware-reserved memory when Windows can obtain those details.
Installed RAM and usable RAM can differ
Windows may show less usable memory than the physical amount installed because hardware can reserve part of the address space. A large unexpected difference can justify checking firmware settings, memory installation, or hardware diagnostics.
If you are planning an upgrade
Do not buy memory based only on the amount currently installed. Check the laptop or motherboard manufacturer’s specifications for supported memory type, capacity, speed, slot configuration, and whether the RAM is replaceable.
