This error typically indicates that your system has exhausted its virtual memory (page file) rather than physical RAM, or that a specific application is leaking memory resources. Even with ample gigabytes of installed RAM, Windows manages memory by using a portion of your hard drive as an extension called the page file. When this file becomes fragmented, too small, or corrupted, the operating system cannot allocate additional memory space for active processes, triggering the warning despite high available physical memory.
Distinguish Between Physical RAM and Virtual Memory
To understand why this happens, it is crucial to differentiate between Random Access Memory (RAM) and the Page File. RAM is the fast, volatile memory used by running applications. The Page File is a hidden file on your storage drive (usually
pagefile.sys) that Windows uses when RAM is full. If you have 16GB of RAM but only 2GB free, Windows starts moving inactive data to the page file. If the page file itself is maxed out or misconfigured, Windows will report low memory even if physical RAM slots are not fully utilized. This distinction explains why users with large amounts of hardware can still receive this notification.
Increase the Size of Your Page File
The most common fix is to manually increase the size of the virtual memory file. By default, Windows may set this to "Automatically manage paging file size," which sometimes fails to allocate enough space during heavy loads. You can override this setting to ensure sufficient room is reserved.
Follow these steps to adjust your settings:
- Press
Win + S, type Advanced System Settings, and select View advanced system settings.
- In the System Properties window, go to the Advanced tab.
- Under the Performance section, click Settings...
- Navigate to the Advanced tab within the Performance Options window.
- Under Virtual Memory, click Change...
- Uncheck Automatically manage paging file size for all drives.
- Select your primary drive (usually C:).
- Select Custom size. Set the Initial size (MB) to 1.5 times your physical RAM, and the Maximum size to 3 times your physical RAM. For example, if you have 16GB (16384 MB), set initial to 24576 and maximum to 49152.
- Click Set, then OK.
- Restart your computer to apply the changes.
After restarting, monitor your system. If the error persists, proceed to the next troubleshooting step. Note that having a sufficiently large page file requires adequate free space on your SSD or HDD. If your drive is nearly full, consider cleaning up files first.

Identify Memory-Leaking Applications
Sometimes the issue is not the total capacity but how specific programs consume memory. A memory leak occurs when an application fails to release memory it no longer needs, gradually consuming more and more resources until the system runs out. To identify the culprit, use the Task Manager.
Press
Ctrl + Shift + Esc to open Task Manager. Click on the
Memory column header to sort processes by usage. Look for any non-system process that is consistently using a high percentage of memory (e.g., over 10-15%) without a corresponding reason. Common offenders include web browsers with many tabs open, poorly optimized software, or background services. If you identify a specific program causing the spike, check for updates for that application. Updating often fixes known bugs related to resource management. If the issue persists after updating, consider uninstalling and reinstalling the problematic software.
Check for Malware and Viruses
Malicious software can also cause low memory errors by running hidden processes that consume CPU and RAM resources. Cryptominers, for instance, are notorious for hogging system resources. Run a full system scan using Windows Defender or a trusted third-party antivirus solution. Ensure your definitions are up to date before scanning. Additionally, check for unwanted browser extensions or startup programs that may be running covertly. Disabling unnecessary startup items via the
Startup tab in Task Manager can also reduce the baseline memory load.
Update Drivers and Windows
Outdated or corrupt drivers, particularly graphics card drivers, can lead to memory management errors. Graphics drivers handle significant portions of video memory allocation. If they are outdated, they may fail to release VRAM properly, leading to system-wide memory warnings. Visit your GPU manufacturer’s website (NVIDIA, AMD, or Intel) to download the latest stable drivers. Alternatively, use Device Manager to update them automatically. Furthermore, ensure your Windows 11 installation is fully updated, as Microsoft frequently releases patches that improve memory handling and stability.
Perform a Clean Boot
If the above steps do not resolve the issue, a clean boot can help isolate software conflicts. This involves starting Windows with a minimal set of drivers and startup programs. Type
msconfig in the search bar and open
System Configuration. Go to the
Services tab, check
Hide Microsoft services, and then click
Disable all. Go to the
Startup tab and open Task Manager to disable all startup items. Restart your PC. If the error disappears, re-enable services and startups one by one to find the conflicting application. This methodical approach helps pinpoint the exact source of the problem.
Frequently Asked Questions
Can insufficient disk space cause low memory errors?
Yes, because Windows relies on the page file stored on your hard drive to extend RAM. If your drive is nearly full, Windows cannot write temporary data to it, effectively capping your usable memory regardless of how much physical RAM you have installed.
How do I know if my RAM is physically faulty?
You can use the Windows Memory Diagnostic tool by searching for it in the Start menu and selecting
Restart now and check for problems. This tool tests the physical integrity of your RAM sticks and will report any errors found during the boot process.
Is it safe to set the page file to a very large custom size?
It is generally safe, provided you have enough free disk space. However, setting it excessively large on a small SSD may wear out the drive faster due to increased write cycles. A balanced custom size, as described in the article, is usually optimal.
Why does Chrome or Edge cause low memory warnings?
Modern browsers use multiple processes for each tab and extension to maintain stability. While efficient, opening dozens of tabs can quickly consume hundreds of megabytes or gigabytes of RAM, pushing the system to rely heavily on the page file, which may trigger warnings if the virtual memory limit is reached.
Should I disable the page file entirely to save disk space?
No, disabling the page file is not recommended for most users. Many applications expect virtual memory to exist and may crash if it is unavailable. It also prevents Windows from hibernating properly or dumping memory dumps for debugging purposes.
