If you’re experiencing lag in games or poor performance in graphics-heavy applications, your Video RAM (VRAM) might be limiting your system. This guide will show you how to increase VRAM on Windows 10 and 11 for Intel, AMD, and Nvidia integrated graphics—without BIOS access.

🚀 Why Increase VRAM?

VRAM is crucial for:
✔ Smoother gaming (higher FPS)
✔ Better video editing & 3D rendering
✔ Improved performance in graphic-intensive apps

Most PCs with integrated graphics (Intel HD, AMD Radeon, etc.) share system RAM as VRAM. By adjusting registry settings, you can allocate more memory for better performance.

🔍 Step 1: Check Your Current VRAM

Before making changes, check your current VRAM:

1. Right-click on the desktop and select Display settings.
2. Scroll down and click Advanced display settings.
3. Select Display adapter properties.
4. Under Adapter Information, check Dedicated Video Memory.

If it shows a low value (e.g., 128MB), increasing it can help.

⚙ Step 2: Modify VRAM via Registry Editor

⚠ Warning: Editing the registry incorrectly can cause system issues. Backup your data before proceeding.

A. Open Registry Editor

1. Press Win + R, type regedit, and run as Administrator.
2. Navigate to:

   HKEY_LOCAL_MACHINE\Software

• For Intel, go to Intel folder.
• For AMD, look for AMD folder.
• For Nvidia, find Nvidia Corporation.

B. Create a New GMM Key

1. Right-click on your GPU manufacturer’s folder (e.g., Intel).
2. Select New > Key and name it GMM (all uppercase).
3. Inside GMM, right-click > New > DWORD (32-bit) Value.
4. Name it DedicatedSegmentSize (case-sensitive).

C. Set the Correct VRAM Value

First, check your installed RAM:

• Press Win + R, type msinfo32, and check Installed Physical Memory (RAM).

Now, set the DedicatedSegmentSize value based on your RAM:

System RAM	Recommended VRAM (Decimal Value)
1GB RAM	128
2GB RAM	256
4GB RAM	512
8GB RAM	2048
16GB RAM	2048

5. Double-click DedicatedSegmentSize, enter the value, and click OK.
6. Restart your PC for changes to take effect.

🛠 Step 3: Update Graphics Drivers (Optional)

For best performance, ensure your GPU drivers are up-to-date:

1. Right-click Start > Device Manager.
2. Expand Display adapters, right-click your GPU, and select Update driver.
3. Choose Search automatically for drivers.

Alternatively, download drivers from:

• Intel Graphics Drivers
• AMD Drivers
• Nvidia Drivers

❓ Does This Really Increase VRAM?

This method tells Windows to allocate more system RAM as VRAM, improving performance in some cases. However:

• Integrated GPUs still rely on shared memory.
• Dedicated GPUs (Nvidia/AMD discrete cards) have fixed VRAM and won’t benefit from this tweak.

If your system still struggles, consider:
✔ Adding more RAM
✔ Upgrading to a dedicated GPU

🔥 Final Thoughts

Increasing VRAM via the Registry can boost gaming and GPU performance on budget PCs. While it’s not a magic fix, it helps optimize memory allocation.
