Upgrading your computer’s memory (RAM) can be tricky if you’re not sure what type you have. With Windows 11, many modern PCs use DDR4 or DDR5 RAM, but knowing which one your system supports is important before buying an upgrade. In this step-by-step guide, we’ll show you different ways to check whether your RAM is DDR4 or DDR5 on Windows 11 — no guesswork needed.
Why RAM Type Matters
Imagine buying a brand-new set of DDR5 sticks only to realize your motherboard only supports DDR4. That’s like trying to fit a key into the wrong lock — it simply won’t work. Knowing whether you’re running DDR4 or DDR5 RAM on Windows 11 ensures you upgrade correctly, avoid compatibility issues, and get the best performance for your system.
What Are DDR4 and DDR5 RAM?
DDR4 (Double Data Rate 4): Standard memory type for most PCs built between 2015–2021.
DDR5 (Double Data Rate 5): The latest generation, faster, and more power-efficient, found in newer systems (2021 onward).
Key Differences Between DDR4 and DDR5
| Feature | DDR4 | DDR5 |
|---|---|---|
| Release Year | 2014 | 2020 |
| Speed Range | 1600–3200 MT/s | 4800–8400+ MT/s |
| Voltage | 1.2V | 1.1V |
| Max Capacity per DIMM | 32GB | 128GB+ |
| Latency | Lower | Slightly higher initially |
Why Should You Check RAM Type on Windows 11?
Upgrade compatibility – DDR4 and DDR5 are not interchangeable.
Performance needs – DDR5 supports higher speeds and multitasking.
Future-proofing – Knowing your RAM type helps plan long-term upgrades.
Method 1: Check RAM Type Using Task Manager
Unfortunately, Windows 11’s Task Manager doesn’t show DDR version directly — but it does show speed, slots used, and form factor.
Steps:
Right-click Taskbar → select Task Manager.
Go to the Performance tab.
Click Memory.
Here, you’ll see:
Total RAM size
Speed (e.g., 3200 MHz, 4800 MHz)
Slots used
💡 Tip: If speed shows above 4800 MHz, you’re almost certainly on DDR5.
Method 2: Check RAM Type via Command Prompt (CMD)
Steps:
Press Windows + S and type
cmd.Right-click → Run as administrator.
Enter the following command:
If
MemoryType= 24 → DDR3, 26 → DDR4, 34 → DDR5.
Method 3: Check RAM Type Using PowerShell
Steps:
Press Windows + X → Select Windows PowerShell (Admin).
Paste this command:
Look for the MemoryType code:
26 = DDR4
34 = DDR5
Method 4: Use Third-Party Tools (CPU-Z, HWInfo)
If you want more detailed info:
CPU-Z → Free software, shows RAM type under the Memory tab.
HWInfo → Advanced system monitoring, shows DDR version, timings, and modules.
Method 5: Check System Information in BIOS/UEFI
BIOS/UEFI often lists RAM details.
Steps:
Restart your PC.
Press the BIOS key (usually Del, F2, or Esc) during startup.
Navigate to Memory Information.
How to Identify RAM Type Physically (Manual Check)
If all else fails, check the RAM stick itself:
Power off your PC and remove the RAM.
Look at the label or sticker on the module — it usually states DDR4 or DDR5.
DDR4 vs DDR5: Performance Comparison Table
| Task | DDR4 Performance | DDR5 Performance |
|---|---|---|
| Gaming | Good | Better at higher resolutions |
| Multitasking | Strong | Much stronger |
| Future upgrades | Limited | Highly scalable |
Common Mistakes When Checking RAM Type
Confusing RAM speed with DDR version.
Using outdated tools that don’t detect DDR5.
Assuming all modern PCs use DDR5 — many still ship with DDR4.
Can You Upgrade DDR4 to DDR5 Without Changing Motherboard?
❌ No. DDR4 and DDR5 use different slots. You’ll need a new motherboard and CPU that supports DDR5.
Troubleshooting: What If Windows Doesn’t Show RAM Type?
Update BIOS/UEFI firmware.
Try third-party tools like CPU-Z.
Physically check the RAM module.
Final Thoughts: Choose the Right Upgrade Path
Checking if your RAM is DDR4 or DDR5 on Windows 11 is easier than it seems. Whether you use Task Manager, CMD, PowerShell, BIOS, or CPU-Z, the process only takes a few minutes. By knowing your RAM type, you can make smarter upgrade decisions, avoid costly mistakes, and keep your system running at peak performance.
FAQs
1. How can I tell if my laptop has DDR4 or DDR5 RAM?
Use Task Manager or CPU-Z. Most laptops built before 2022 use DDR4, newer models may use DDR5.
2. Can DDR4 RAM work in a DDR5 motherboard?
No. DDR4 and DDR5 are not physically compatible.
3. Does Windows 11 require DDR5 RAM?
No. Windows 11 works with both DDR4 and DDR5.
4. Which is better for gaming: DDR4 or DDR5?
Both work well, but DDR5 offers better performance for future-proof gaming.
5. What’s the easiest way to check RAM type for beginners?
Download CPU-Z — it instantly shows whether you have DDR4 or DDR5.
