Below we have explained in more detail:-

  • Having 32-bit Windows Version- If you have a 32-bit Windows operating system, you will need to reinstall it as 64-bit. Windows version 64 has a much larger capacity than 32-bit, which means you can use more ram for other tasks.
  • Turn On Auto Ram Virtualization- By default, the ram virtualization option is enabled, which prevents the ram from being used at full usage. Ram virtualization creates an area as a paging file in the hard disk for Windows to use ram. If you disable the option, the issue may resolve as your ram will not be used much by the Windows on the hard disk.
  • Defective or Incompatible Ram- According to the users, the issue can be resolved by replacing the ram if it gets damaged or is incompatible. Hence, make sure your ram is not damaged as it can cause issues.
  • Outdated System Bios– Another cause that can lead you to this issue is an outdated bios system because there may be a chance that you have an old system that may not support the current bios version, and that is why the system cannot access all the ram usage. Therefore, if the current bios get outdated, update the bios to the latest version. 
  • Having Integrated GPU- If you have an integrated GPU, you cannot use the full memory until you upgrade to the dedicated graphics card, as an integrated GPU uses the memory from your ram, which is why you are not allowed to use full of your Ram.
