Managing Your Computer's Virtual Memory (Page File) In Windows
Posted by DTG Support (Trains) on 04 June 2020 01:00 PM

The Page File is used as a form of virtual memory that allows you to open lots of files and applications that may need more memory than your computer physically has available. All computers need a Page File, whether you have over 64 GB of System RAM, or just 4 GB, as Windows may need it for important processes that may not be immediately apparent. Our software also requires you to have a Page File and, without one set, it can directly affect the smooth running of the software.

When configured, Windows designates a section of your hard disk space to be used as virtual memory. It is then used to supplement your computer’s System RAM (Random Access Memory) to improve performance for programs and data that are used frequently. Although you cannot browse or directly alter the file that's saved on your hard disk, you can manage it using the Windows System Settings.

Windows 10 usually automatically manages the Page File according to your system configuration and how much System RAM you have available, and it's always a good idea to check it is set up and sufficient for what you need. If you are finding that you're having problems with our software, try increasing the amount of Virtual Memory (Page File) you have available to see if it improves. We outline below the steps on how to do this:

Important Note:

This guide is technical in nature and should not be attempted if you:

  1. Do not understand any of the terms used in this document;
  2. Are not confident in your ability to carry out the instructions given.

If you are at all unsure of this, we would recommend you ask a local computer professional or someone you trust to do this for you.

Before you begin, it’s important that:

  • You log on to your computer as an administrator to change your Virtual Memory Settings. If you don't have an Administrator account, ask the person who does, to do this for you.
  • You save any work you may have running as changing any settings for Virtual Memory will require you to restart your computer.
  • You have enough available hard disk space that is equivalent to quadruple the capacity of your System RAM i.e. if your computer has 4 GB of System RAM, check that you have at least 16 GB of hard disk space free.

If you’re using Windows 10, Windows 8 or 8.1

  1. From Start, search for Settings and select Settings from the search results (or use the Windows shortcut Win Key + I).
  2. On the Settings window, tap or click System, then tap or click to select About.
  3. In the About section, look for the section called Related Settings in the upper right, tap or click System Info.
  4. On the System Information window, tap or click Advanced System Settings.
  5. On the System Properties window, under the Performance section, tap or click Settings.
  6. On the Advanced tab of the Performance Options window, it will advise how much Virtual Memory is assigned. Tap or click Change.
  7. On the Virtual Memory dialog box, ensure a check appears in the box at the top where it says Automatically manage paging file size for all drives or, if you wish to change the amount of Virtual Memory available, select a hard disk from the list, then set either Custom Size or System managed size from the options below paying particular care to use MB (Megabytes) to define the size where 1 GB is equal to 1024 MB.
  8.  
  9. Note the maximum size you can assign to a page file is four times your available System RAM i.e. if your total System RAM is 4 GB (4096 MB), the maximum size you can set is 16 GB (16384 MB). However, it is recommended you allow at least 1.5 times as a minimum i.e. if your total System RAM is 4 GB, you should allow at least 6 GB (6144 MB).
  1. Once you've entered the values you wish to use or have set System managed size, tap or click the Set button, then click OK. It is also worth noting that you can have different sizes set on more than one hard disk, if you so wish. However, be careful when setting this as not all hard disks are the same and some may be slower and may in fact slow your computer down. If you experience a signifcant slow down, try to limit the number of hard disks where a page file is set.
  2. You may be prompted to restart your computer for the changes to take effect. If not, you should do so anyway as your changes will not be used until you do.
