Whether you’re planning a RAM upgrade, troubleshooting performance issues, or just curious about your PC’s memory, knowing your RAM type (DDR3, DDR4, DDR5), speed, and form factor is essential. Windows 11 makes it easy to check RAM information using built-in tools like Task Manager, Command Prompt, and PowerShell—no need to open your computer or install third-party apps.
In this guide, we show you all the reliable ways to check your RAM type, speed, and other details right from Windows 11.
How to Check RAM Type in Windows 11
To follow this guide, you’ll need a basic access to system tools like Task Manager, Command Prompt, and PowerShell. You don’t need administrator privileges for most steps unless you’re querying advanced memory details. As long as your PC is turned on and running Windows 11, you’re ready to check your RAM type.
1. Check RAM Type Using Task Manager
Task Manager doesn’t display DDR type directly, but it does show detailed RAM information, including usage, speed, and available slots.
- Press Ctrl + Shift + Esc to open Task Manager.
- Switch to the Performance tab.
- Click Memory on the left side.
- Here you can check:
- Speed (MHz)
- Form factor (DIMM/SODIMM)
- Used slots
- Total RAM capacity
While it doesn’t say “DDR4” or “DDR5,” the speed gives you a hint. To get the exact RAM type, use the next methods.
2. Check RAM Type Using Command Prompt (DDR3/DDR4/DDR5)
Command Prompt is the easiest built-in tool to check your RAM type.
- Press Windows + R, type cmd, and press Enter.
- Run this command:
wmic memorychip get Devicelocator, MemoryType, TypeDetail
MemoryType Values
- 20 = DDR
- 21 = DDR2
- 24 = DDR3
- 26 = DDR4
- 34 = DDR5
If you see 26, that means DDR4. If you see 34, that means DDR5.
Note: Sometimes the MemoryType value may show 0, which means Windows couldn’t read it. Use PowerShell instead.
3. Check RAM Type Using PowerShell (Most Accurate)
PowerShell provides more accurate DDR type information along with speed and manufacturer details.
- Press Windows + X and select Windows Terminal (PowerShell).
- Run this command:
Get-CimInstance Win32_PhysicalMemory | Format-Table Manufacturer, BankLabel, SMBIOSMemoryType, Speed
SMBIOSMemoryType Values
- 20 = DDR
- 21 = DDR2
- 24 = DDR3
- 26 = DDR4
- 34 = DDR5
You’ll also see your RAM speed (e.g., 3200 MHz) and manufacturer (Samsung, SK Hynix, Micron, etc.).
4. Check RAM Type in System Information
System Information shows basic memory details.
- Press Windows + R, type msinfo32, and hit Enter.
- Look for:
- Installed Physical Memory (RAM)
- Available RAM
This doesn’t show DDR type directly but helps confirm capacity.
5. Use the Manufacturer’s Website to Confirm RAM Type
If your PC is prebuilt (Dell, HP, Lenovo, Asus, etc.) or if you’re using a laptop, you can confirm RAM type from the spec sheet.
- Press Windows + R, type msinfo32, and press Enter.
- Note your System Model.
- Search this model on the manufacturer’s website.
- Look for Memory or Specifications.
This will list DDR type, maximum supported RAM, and upgrade compatibility.
6. Check RAM Type in BIOS/UEFI
Your BIOS or UEFI often displays advanced memory details.
- Restart your PC.
- Press the BIOS key (F2, Delete, Esc, or F10 depending on manufacturer).
- Navigate to Memory, Advanced, or System Information.
Here you’ll typically find:
- DDR type
- RAM clock speed
- Total memory
- XMP/DOCP status
If you’re planning upgrades, checking RAM compatibility here helps a lot.
7. Use Third-Party Tools Like CPU-Z (Optional)
If you prefer a one-click solution:
- Download CPU-Z (free).
- Go to the Memory tab.
- Check Type, Size, and DRAM Frequency.
CPU-Z is extremely accurate and beginner friendly.
What the RAM Type Tells You
Here’s what your RAM type means:
DDR3
- Older standard
- Slower speeds (1333–1866 MHz)
- Not compatible with DDR4 or DDR5 slots
DDR4
- Most common today
- Speeds from 2133–3600+ MHz
- Not compatible with DDR5
DDR5
- Latest generation
- Faster speeds (4800 MHz and above)
- Found mostly in new laptops and gaming PCs
Knowing your RAM type is essential before upgrading, as DDR types are not interchangeable.
Wrapping Up
Checking your RAM type on Windows 11 is easy using tools like Command Prompt, PowerShell, Task Manager, and BIOS. Whether you’re planning an upgrade or troubleshooting slow performance, knowing if your system uses DDR3, DDR4, or DDR5 helps you choose the right memory modules and avoid compatibility issues.
After following the steps in this guide, you should clearly understand your RAM type, speed, and other key details on your Windows 11 PC.
