# How to Set Virtual Memory to the Same Size as RAM (Windows)

## Summary

Virtual memory (pagefile) acts as backup RAM on your disk.

If the pagefile is too small, you may experience memory errors, crashes, or performance issues.

Below are the steps to configure it correctly.

## Action Required

1. **Check your installed RAM**:
  1. Press the **Windows** key.
  2. Type **System Information** and open it.
  3. Look for **Installed Physical Memory (RAM)**. For example: *16.0 GB*
  4. Write this number down.
2. **Open Virtual Memory settings**:
  1. Press the **Windows** key+ **R**.
  2. Type **sysdm.cpl** and press **Enter**.
  3. In the **System Properties** dialog, go to the **Advanced** tab.
  4. Under **Performance**, click **Settings**.
  5. Go to the **Advanced** tab.
  6. Under **Virtual memory**, click **Change**.
3. **Configure the pagefile (virtual memory):**
  1. In the **Virtual Memory** dialog, deselect the **Automatically manage paging file size for all drives** check box.
  2. Select drive **C:** or your system drive.
  3. Choose **Custom size**.
  4. Set **Initial size (MB)**, which is the RAM size in MB. For example: 16 GB RAM → 16 × 1024 = **16384 MB**.
  5. Set **Maximum size (MB)**, which is the same value. For example, **16384 MB**.
  6. Click **Set**.
  7. Click **OK**.
  8. Restart your computer.
