01.Introduction: What is the Pagefile?
When your physical RAM reaches capacity, Windows moves the least active data to your storage drive. This area of the drive is the Pagefile. If you disable it, the moment your RAM hits 100% usage, your programs will instantly experience a "Crash to Desktop" (CTD).
Don't do it Manually.

02.Chapter 1: Configuration Steps
Step-by-Step Setup
1. Search for "Adjust the appearance and performance of Windows" in the Start menu.
2. Go to Advanced tab > Virtual Memory > Change.
3. Uncheck "Automatically manage paging file size for all drives."
4. Select your C: (SSD) drive.
5. Select "Custom size."
03.Chapter 2: Fixed Size vs. System Managed
We strongly recommend using a Fixed Size (setting both Initial and Maximum size to the same value).
Why? If the size is dynamic (e.g., 1GB to 20GB), Windows consumes CPU cycles constantly resizing the file during gameplay, which can lead to stutters. By fixing the size, the file is created once, remains static, and provides faster access.
04.Chapter 3: Recommended Values
Practical rule for Gamers (Values in MB):
- 8GB RAM: Set to 16000 MB (Requires significant paging support).
- 16GB RAM: Set to 16000 MB or 12000 MB. (Essential for Warzone/Tarkov).
- 32GB RAM: Set to 4096 MB or leave as System Managed. (Rarely used, kept for stability).
A1.Chapter 4: SSD vs. Mechanical HDD
NEVER place the Pagefile on a mechanical HDD.
Hard drives are exponentially slower than RAM. If a game needs to read paging data from an HDD, you will experience severe 1-second stutters.
Configure the Pagefile ONLY on your fastest SSD (NVMe preferred). Select "No paging file" for all secondary mechanical HDDs.
A2.Chapter 5: Committed Memory and System Commit
Certain simulation titles (Star Citizen, DCS World) will crash if the "System Commit" cannot reach 40GB or more.
System Commit = Physical RAM + Paging File size.
If you have 16GB of RAM, you need a 24GB Pagefile to reach the 40GB total commit charge required by these heavy simulators.
A3.Chapter 6: The Myth of Disabling the Pagefile
In the past, users were advised to disable paging to "save SSD lifespan."
Modern SSDs can handle petabytes of writes. Disabling paging only introduces system instability. Windows is architected to utilize the pagefile even for low-priority background tasks, regardless of how much RAM you have. Keep it enabled.
Chapter 7: Intelligent Standby List Cleaner (ISLC)
ISLC is a tool that automatically clears the Windows standby list cache.
It is particularly useful if you find that games start smoothly but begin to stutter after an hour of play.
Configure it to clear when "Free Memory" is lower than 1024MB.
Chapter 8: Paging Faults (BSOD Errors)
Encountering a "PAGE_FAULT_IN_NONPAGED_AREA" Blue Screen?
This is typically caused by faulty RAM or unstable overclocking (aggressive XMP/EXPO), not your paging file size configuration. Run MemTest86 to verify hardware stability.
Chapter 9: Disk Space Awareness
Remember: If you define a 16GB pagefile, you lose 16GB of SSD storage immediately. Always ensure you have sufficient free space; a nearly full SSD can become significantly slower (performance degradation).
Chapter 10: The Required Reboot
Any changes made to your Virtual Memory settings require a full Windows restart to take effect.
