Software Prompting "Insufficient Memory"

Users may experience FreeScan / EXScan / OptimScan software prompting 

"Insufficient Memory" while scanning.

This is usually caused by low or nearly full system memory (RAM). 

When this prompt appears, you may also encounter the following related 

problems:

1. Unable to continue scanning;
2. Unable to open project with original resolution; forced downsampling is required to load the project successfully;
3. Software crashes or computer blue screen (BSOD) when opening projects;
4. Mesh Processing / Optimization requires larger resolution;
5. Software crashes during Mesh & Mesh Editing.

Solution: Adjust Virtual Memory

Virtual memory uses part of your hard drive as spare system memory 

when physical RAM runs low. Setting it to twice your physical RAM can fix 

the Insufficient Memory issue in the scanning software. 

Below is the setup guide for Windows 10/11.

Step 1 Check Your Physical Memory (RAM) Size

1. Right-click the Windows Start button.

2. Select System from the right-click pop-up menu.

3. Find the "Installed RAM" to check your physical memory capacity.

Step 2: Access Virtual Memory Settings Panel

1. Scoll down and select Advanced System Settings.

2. In the pop-up "System Properties" window, switch to the Advanced tab, then click Settings under the "Performance" category.

3. In the "Performance Options" window, go to the Advanced tab, then click Change under the "Virtual Memory" section.

Step 3: Configure Virtual Memory

 (C drive is usually smaller and may have permission issues for it's the system drive, but if you only have C drive, then selecting C drive is also acceptable.)

3. Choose Custom size, and enter the corresponding values in megabytes (MB) based on your physical RAM: 

4. Click Set (this step is mandatory to save the configuration), then click OK to close all setting windows in sequence.

Step 4: Restart Your Computer

Restart your computer to activate the new virtual memory settings. 

After rebooting, insufficient memory and related issues will be significantly 

relieved.

Supplementary Tips:

Adjusting virtual memory is an effective solution for persistent Insufficient Memory 

issues. For long-term stable and high-efficiency scanning, upgrading physical RAM is 

the most fundamental method.
