How Much Virtual Memory Should I Set?

How Much Virtual Memory Should I Set?.

Virtual reminiscence acts as a further reminiscence useful resource in your system if it runs out of RAM. For that, it makes use of some reserved disk area, which you’ll discover as a hidden pagefile.sys file.

Since digital reminiscence makes use of up further disk area robotically, it’s not essential to manually restrict its measurement until you expertise any system instabilities.

If nevertheless, you do run into some points, examine the whole reminiscence assets you want in your work. Then, specify the digital reminiscence (pagefile) sizes accordingly.

Let’s talk about every part intimately.

Recommended Virtual Memory Size


Having your system handle the digital reminiscence measurement for all drives is undoubtedly the most suitable choice. 

You will expertise only a few points. Just be sure that to depart behind sufficient free area in your C drive.

If the drive doesn’t have a lot free area, your system will robotically use one other drive for the paging file. You may specify the subsequent drive manually.


The solely time the place you’ll have to manually set the dimensions is once you run into pagefile-related system points. Even then, the quantity of digital reminiscence you want depends upon your system utilization.

With bigger RAMs (16+ GB), your system doesn’t want a whole lot of further reminiscence assets. But for methods with smaller ones, you’ll in all probability run out of reminiscence quickly.

It’s best to have a proportionally bigger digital reminiscence in such instances.

RAM Size (GB) Initial Pagefile Size (MB) Maximum Pagefile Size (MB)
4 GB 2048 8192
8 GB 4096 12288
16 GB 2048 16384
32 GB 1024 8192
My really helpful pagefile sizes for various RAMs

For 64GB+ RAMs, the RAM itself needs to be sufficient for all functions. So you may merely set 1-2 GB for pagefile to account for some uncommon circumstances.

Note: If you want to allow full reminiscence dumps, a pagefile area of your RAM + 257 MB is important.

Determine the Ideal Virtual Memory Size Yourself

The above sizes are my suggestions. They have labored for me and a whole lot of others, however is probably not splendid for you. 

It’s best to estimate the perfect digital reminiscence measurement in your system through the use of Process Explorer, a Microsoft SysInternals instrument.

For that,

  1. Make positive you’ve got sufficient area in your system drive.
  2. Open Run (Windows key + R), kind systempropertiesadvanced, and click on OK.
  3. Click Settings beneath Performance, go to the Advanced tab, and choose Change.system-properties-performance-settings-advanced-change
  4. Make positive Automatically handle paging file measurement for all drives is enabled.
  5. Run all of the apps you’d usually use.
  6. Download Process Explorer from Microsoft Sysinternals. Extract it into your native drive.process-explorer-download-sysinternals
  7. Run Process Explorer (procexp64.exe).
  8. Click on the System Information icon on the highest portion. 
  9. Go to the Memory tab and examine the Peak Commit Charge.process-explorer-peak-commit-charge
  10. Now, disable the automated paging file measurement and manually set it as follows:
    • Initial measurement: Peak Charge – RAM measurement (in MB)
    • Maximum measurement: Twice the preliminary measurement
  11. In my system, the peak commit cost was about 20489960 KB = 20009 MB and my RAM measurement is 8000 MB (8 GB RAM is just about 7.8 GB in actual, which is barely lower than 8000 MB).
    So I set the Initial Size to 20000 – 8000 = 12000 MB, and the Maximum measurement to 24000 MB.virtual-memory-custom-size-initial-max-set
  12. If the height commit cost is lower than the RAM’s capability, set the Initial measurement to 2048 MB and the Maximum to double that quantity.

Extra Tips

  • If you’re using an SSD and an HDD, create the pagefile on the SSD for higher efficiency.
  • If you’re solely using arduous drives, create the pagefile on the OS partition. If you solely play laptop video games, you may also use the sport quantity for this goal.

Isn’t Higher Virtual Memory Better?


Virtual Memory is just not an extension of the RAM however is supposed to be a failsafe in case the RAM is just not sufficient for the energetic processes. Without the digital reminiscence, your system will crash as soon as it runs out of RAM.

The pagefile doesn’t enable operating apps from it and you may’t learn/write knowledge into it. Your system will merely use this area to switch background actions on the RAM to the digital reminiscence.

This manner, your RAM can have more room for energetic processes. Once the system must function on these duties, it’ll switch different knowledge to the digital reminiscence and retrieve the earlier knowledge to the RAM.


Your system will begin using the digital reminiscence for lots of background duties to restrict RAM utilization. The OS will nonetheless use the digital reminiscence as a swap area even when the RAM is just not totally used up.

So, a bigger digital reminiscence might as a substitute carry in regards to the following issues:

What Happens if I Specify Less Virtual Memory Instead?


Your laptop makes use of the pagefile each as further reminiscence assets and to retailer reminiscence dumps.

A smaller digital reminiscence impacts each of those options and causes the next points:
