In this article, we will teach you about virtual RAM and its management in modern computing systems. Understanding virtual RAM and how it functions can enhance your knowledge of memory management and system performance.
How does virtual RAM work?
Virtual RAM works by extending the capabilities of physical RAM using disk space. When the physical memory becomes insufficient to handle running applications, the operating system uses a section of the hard drive or solid-state drive (SSD) as a temporary storage area. This process involves creating a swap file or page file, where inactive data from RAM is stored.
When an application requests data, the system checks if it is available in physical RAM. If not, the system retrieves the data from the swap file, temporarily swapping out other less-used data from RAM to make room. This allows for the illusion of having more RAM than is physically available, facilitating multitasking and improving system responsiveness.

How is virtual memory managed?
Virtual memory is managed by the operating system through a process called paging. The OS keeps track of the data stored in physical memory and the data swapped out to the disk. When an application accesses data that has been moved to the disk, the OS retrieves it and may swap other data back to the disk to maintain optimal performance.
The management of virtual memory involves algorithms that determine which data should remain in RAM and which should be moved to the disk based on usage patterns. Most operating systems provide settings for users to configure the size of the virtual memory (page file) according to their needs, allowing for adjustments based on available disk space and system performance.
What happens if I increase the RAM on my phone?
If you increase the RAM on your phone, you will generally notice improved performance. More RAM allows your device to run more applications simultaneously without lagging, as there is more physical memory available to store active data. This can enhance multitasking capabilities, reduce loading times for apps, and improve the overall user experience, especially when using resource-intensive applications or games.
However, it’s essential to note that not all smartphones allow for RAM upgrades, as many are designed with soldered RAM. In such cases, upgrading the device may require purchasing a new phone with higher RAM specifications.
How to increase virtual RAM?
To increase virtual RAM, you typically need to adjust the settings for the page file or swap space on your operating system. Here’s how to do it on a Windows PC:
- Open System Properties: Right-click on “This PC” or “Computer” on your desktop or in File Explorer, and select “Properties.” Then click on “Advanced system settings.”
- Access Performance Options: In the System Properties window, navigate to the “Advanced” tab and click on “Settings” under the Performance section.
- Modify Virtual Memory Settings: In the Performance Options window, go to the “Advanced” tab and click on “Change” under the Virtual Memory section. Uncheck “Automatically manage paging file size for all drives.”
- Set Paging File Size: Select the drive where you want to increase virtual RAM. You can choose “Custom size” and enter the initial and maximum size values in megabytes (MB). Alternatively, you can allow the system to manage the paging file size automatically.
- Save Changes: Click “Set” and then “OK” to save your changes. Restart your computer for the new settings to take effect.
We hope this explanation helped you understand virtual RAM and how it functions within your devices. Understanding these concepts can significantly improve your ability to manage system performance effectively.
