How to optimize RAM in modern Windows operating systems

Optimizing random access memory (RAM) in modern Windows operating systems is an important task to ensure stable and fast computer operation. Insufficient memory can lead to system slowdowns, application crashes, and general instability. In this article we will look at various methods for optimizing RAM, as well as problems that may arise when it is insufficient.

Reasons for lack of RAM

  • Running multiple applications: Running a large number of programs simultaneously requires significant RAM resources.
  • Programs running in the background: Many background processes, such as antivirus programs, cloud storage synchronization, and updates, can consume a significant portion of RAM.
  • System services and components: Some system services can be resource intensive.
  • Memory leaks: Improperly running applications may not release memory after shutdown, causing it to gradually fill up.
  • Insufficient physical memory: Legacy systems with little RAM often experience performance issues.

Methods for optimizing RAM

Application startup management:

Open Task Manager (Ctrl+Shift+Esc) and go to the “Startup” tab.

Disable unnecessary programs that start with the system.

Using built-in Windows tools:

Disk Cleanup: Open This PC, right-click your system drive (usually C:), select Properties, then click Disk Cleanup. This will free up disk space and reduce the amount of memory used.

Troubleshooter: Under Settings → Update & Security → Troubleshooter, you can find tools to optimize system performance.

Setting up the swap file:

Open System Settings, go to the Advanced tab, then click the Settings button under Performance.

In the window that appears, go to the “Advanced” tab and click the “Change” button in the “Virtual memory” section.

Set the paging file values manually based on the amount of RAM you have. For example, on a system with 8 GB of RAM, you can set the page file size from 8 to 16 GB.

Driver Update:

Make sure all drivers, especially for your graphics card and chipset, are updated to the latest version. This can significantly improve system performance and stability.

Using specialized software:

There are utilities for optimizing RAM, such as CCleaner, Wise Memory Optimizer and others. They help free up memory by closing unnecessary processes and cleaning up system resources.

Physical RAM upgrade:

If software methods do not help, consider increasing the amount of RAM. Modern applications and systems require at least 8 GB of RAM for comfortable operation, and preferably 16 GB or more.

Problems with insufficient RAM

System slowdown: One of the first signs of low RAM is a slow computer. Applications take longer to open and operations are slow.

Frequent freezes and crashes: Insufficient memory can cause applications and the system as a whole to freeze.

Blue Screen of Death (BSOD): Critical errors caused by insufficient resources may result in a Blue Screen of Death.

Increased load on the hard drive: The system begins to actively use the paging file on the hard drive, which slows down the computer and can cause wear and tear.


Optimizing RAM in Windows requires a comprehensive approach, including managing startup, using built-in system tools, setting up the page file, updating drivers and, if necessary, physically increasing the amount of RAM. Performing these activities regularly will help keep your system running smoothly and quickly, preventing problems associated with low RAM.
