Virtual ram windows 10

In Windows computers, Virtual memory is used in place of the physical RAM when it runs out of usable space. Virtual memory combines your computer’s RAM with temporary space on your hard disk called the Swap file, Paging file or Pagefile. Whenever RAM is not enough to complete the task windows moves data to the paging file and frees up RAM so that your computer can complete its task. And prevent issues like slow down of the machine, Blue Screen of Death (BSOD), Low Memory problems, App Crashes Etc.

Virtual memory can be considered as being an extension of the computer’s physical memory.

Your computer has two types of memory: The hard drive or solid-state drive, used for your operating system, photos, music and documents, and RAM (Random Access Memory) used for storing program-specific data. The hard drive is perfect for long-term storage, while RAM is much faster and more volatile, acting as a working area for the programs and files you have open.

Every time you open more applications than the RAM on your PC can accommodate, the programs already present in the RAM are automatically transferred to the Pagefile. This process is technically called Paging. Because the Pagefile works as a secondary RAM, many times it is also referred to as virtual memory in windows 10.

Increasing Virtual Memory in Windows 10

Windows 10 and windows 11 manage Virtual memory itself only, But at times you might be required to alter the memory allocated. It is always said to customize the virtual memory into a size that is within the permissible limit. Here is Fallow To manually Adjust Virtual memory for windows computers.

  • First press the combination of Win + R keys together to open the Run dialog box.
  • Here type sysdm.cpl on it and then click on the OK button.
  • This will open “System Properties” of your computer.
  • Go to the Advanced tab and click on the Settings option. Which is available under the “Performance” section.
  • Now On the “Performance Options” window, go to the Advanced tab and click on the Change button located under the “Virtual Memory” section.
  • You will see the Virtual Memory window on your computer screen.
  • Here you have to uncheck the “Automatically manage paging file size for all drive” option at the top of the same window.
  • Select any of the Drive letters where you allow to create the paging file and then click on Custom size.
  • Then enter custom fields in the “Initial size (MB)” and “Maximum size (MB)” fields.

How To Calculate pagefile size

To Calculate the pagefile size always recommended amount (Refer above image) of total system memory. The maximum size is three (1.5) x the initial size. So let’s say you have 4 GB (1 GB = 1,024 MB x 4 = 4,096 MB) of memory. The and maximum size would be 1.5 x 4,096 = 6144 MB.

After Set the Initial size (MB)” and “Maximum size (MB)” Value and click on set, Now Click on the OK button and then on the Apply button to save changes. This will prompt to Restart the window ” you must restart your computer to apply these changes. ”

This is the Best and simple way to Increase Virtual Memory in Windows 10.

On Windows 10, virtual memory (or paging file) is an essential component (hidden file) designed to remove and temporarily store less frequently used modified pages allocated in RAM (Random-Access Memory) to the hard drive. Using this approach lets the system prioritize faster physical memory for more frequent processes and apps, improving the overall performance and preventing the computer from locking up in the event it runs out of system memory.

In addition, the paging file is important to support crash dumps during a system crash (Blue Screen of Death), as without a large enough page file, a dump with all the contents of the system memory won’t be created.

Although the system can manage the paging file size automatically according to various factors, sometimes, you may still need to increase the default virtual memory values manually. For example, when you see the «Your system is low on virtual memory» message. You’re noticing slow performance over time, or a particular application requires specific parameters to work correctly.

If the computer has issues with virtual memory, the device doesn’t have enough memory, or you’re trying to improve the system performance, Windows 10 includes the settings to increase the size of the virtual memory in at least two ways using the Settings app and Command Prompt.

In this how-to guide, I will walk you through the steps to increase the size of the virtual memory to improve Windows 10 responsiveness.

Warning: Although anyone can change the paging file size, using these instructions is only recommended if you have a valid reason and know what you’re doing.

How to increase virtual memory form Settings

To adjust the virtual memory size on Windows 10, use these steps:

  • Quick tip: The virtual memory size is unique to each device and can’t be generalized. However, usually, it’s recommended to use a number that’s one and a half times the total available memory for the «Initial size» and three times the available memory for the «Maximum size» when possible. You also have to make sure that the device has enough free space to store the new page file.
  1. Click the Set button.
  2. Click the OK button.
  3. Click the OK button again.
  4. Restart your device.

Once you complete the steps, you should notice an increase in performance when navigating Windows 10 as well as when running multiple apps at the same time.

If you need to revert the changes, you can use the same instructions, but on step 10, check the «Automatically manage paging size for all drives» option and restart your device.

How to increase virtual memory from Command Prompt

To modify the paging file size with Command Prompt, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.
  3. Type the following command to understand the current status of the paging file and press Enter: wmic pagefile list /format:list

  1. Type the following command to set the initial and maximum size of the virtual memory and press Enter: wmic pagefileset where name=»C:\\pagefile.sys» set InitialSize=YOUR-INIT-SIZE,MaximumSize=YOUR-MAX-SIZE

This example sets the paging file to «9216» and «12288» megabytes for the initial and maxium size: wmic pagefileset where name=»C:\\pagefile.sys» set InitialSize=9216,MaximumSize=12288

  1. Type the following command to restart your computer and press Enter: shutdown -r -t 00

After you complete the steps, the device will start using the new values for virtual memory, which, if done correctly, should help to improve system performance.

If you no longer need to use the custom size for virtual memory, you can always revert the changes and allow Windows 10 to manage this feature using this command: wmic computersystem where name=»%computername%» set AutomaticManagedPagefile=true and restart the computer.

While it’s recommended to use one and a half times the available memory for the initial and three times the memory for the maximum size, make sure to test the changes and adjust the values if you’re experiencing freezes, crashes, and other problems.

Although it’s possible to disable virtual memory on Windows 10, even when you have a large amount of system memory, it’s not recommended to disable this feature. Usually, if you disable paging file, some applications may stop working, some system features may not work efficiently, and you may end up with some weird behaviors.

Optimizing Virtual Memory in Windows has always been an easy way to fine-tune the performance of a computer. When I started working with Windows computers in the 90s, the memory measurement was Megabytes (MB); now, it’s Gigabytes (GB). The calculation contained in this article is for Windows computers that have 8 GB or less of memory. If your system has 16 GB or more of memory, you can give this Virtual Memory calculation a try, but you might find that letting Windows automatically manage the paging file will work. Give it a try, and let us know how you make out in the comments below.

Your computer has two types of memory: Random Access Memory (RAM) and Virtual Memory. All programs use RAM, but when there isn’t enough RAM for the application you’re trying to run, Windows temporarily moves information that would usually be stored in RAM to a file on your hard disk called a Paging File. The data temporarily stored in the paging file is also referred to as virtual memory. Using virtual memory, in other words, moving information to and from the paging file, frees up enough RAM for running programs correctly.

The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate. However, your computer can read data from RAM much faster than from a drive, so adding RAM is a better solution.

If you receive error messages that warn of low virtual memory, you need to add more RAM or increase your paging file size to run the program on your computer. Windows usually manages this automatically, but you can manually change the virtual memory size if the default size isn’t large enough for your needs.

If you have more than one drive in your computer, you can have more than one pagefile. If you have a Solid State Drive (SSD) and a Hard Disk Drive (HDD), I recommend placing the paging file on the HDD, as Windows is continuously reads and writes to the virtual memory. This wear and tear can shorten the life span of an SSD.

How to calculate Windows 10 Virtual Memory / Paging File

There is a formula for calculating the correct pagefile size. The Initial size is one and a half (1.5) x the amount of total system memory. The Maximum size is three (3) x the initial size. So let’s say you have 4 GB (1 GB = 1,024 MB x 4 = 4,096 MB) of memory. The initial size would be 1.5 x 4,096 = 6,144 MB, and the maximum size would be 3 x 6,144 = 18,432 MB.
