How to Check RAM on Windows 11 (4 Easy Ways)

Quick Answer

• Fastest way: press Ctrl + Shift + Esc, open Performance, and click Memory.
• Simple way: go to Settings > System > About and read “Installed RAM”.
• For full details, use System Information (msinfo32) or PowerShell.
• Task Manager also shows live RAM use, speed, and slots used.
• If “usable” RAM is lower than “installed” RAM, some memory is reserved by the system.

Why check your RAM?

RAM is your PC’s short-term memory. If it is too low, apps open slowly and the PC freezes. Checking it helps you decide if you need an upgrade, or if the real problem is something else. It is also a basic check before you install new software or a game. You can compare your numbers against the Windows 11 system requirements.

Method 1: Check RAM in Settings (simplest)

1. Press Windows + I to open Settings.
2. Click System.
3. Scroll down and click About.
4. Look under Device specifications.
5. Find Installed RAM.

You will see something like “16.0 GB (15.8 GB usable)”. The first number is what is installed. The second is what Windows can use.

Method 2: Check RAM in Task Manager (most details)

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Performance in the left menu.
3. Click Memory.

Here you can see:

• Total memory at the top right.
• Speed in MHz.
• Slots used, for example “2 of 4”.
• Form factor, such as DIMM (desktop) or SODIMM (laptop).
• In use and Available, which change live as you work.

This is the best place to see if your PC is running out of memory right now.

Method 3: Check RAM in System Information

1. Press Windows + R.
2. Type msinfo32 and press Enter.
3. In System Summary, scroll to the memory lines.

You will see:

• Installed Physical Memory (RAM)
• Total Physical Memory
• Available Physical Memory

This view is useful when you need exact numbers to share with support or to compare with an app’s requirements.

Method 4: Check RAM type and speed with PowerShell

Use this if you want to know if your RAM is DDR4 or DDR5, who made it, and how many sticks you have.

1. Right-click the Start button.
2. Click Terminal (or Windows PowerShell).
3. Paste this command and press Enter:

Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, Capacity, Speed, SMBIOSMemoryType

How to read the result:

• Capacity is in bytes. 8589934592 means 8 GB. 17179869184 means 16 GB.
• Speed is in MHz.
• SMBIOSMemoryType: 26 usually means DDR4, and 34 usually means DDR5.

Each row is one memory stick, so two rows mean two sticks.

Why is usable RAM lower than installed RAM?

You may see “16 GB (15.8 GB usable)”. This is normal. Some memory is reserved for hardware, such as integrated graphics. If the gap is very big, for example 16 GB installed but only 8 GB usable, one stick may not be seated properly, or a BIOS setting may limit it.

How much RAM do you need?

These are general guides, not strict rules. Apps like Chrome can use a lot of memory when many tabs are open. If your PC feels slow, clearing Chrome cache and closing heavy tabs can help before you buy more RAM.

Quick fixes if RAM is almost full

• Close apps you are not using.
• Restart your PC to clear memory leaks.
• In Task Manager, click Processes and sort by Memory to find heavy apps.
• Turn off extra startup apps.
• Check for updates, since some builds have bugs. See Windows 11 update issues.
