Why Windows Won't Use Full RAM

The common reasons for this issue include the following:

• Memory allocation for hardware. Some hardware components in your system could use part of your RAM. 
• Virtual memory settings. The Virtual memory feature may consume a significant chunk of your RAM if enabled.
• BIOS settings. Incorrectly configured BIOS settings may affect how the system utilizes the RAM.
• 32-bit OS version. The system will only utilize 4GB of RAM for the 32-bit operating system version. It would help if you considered upgrading to 64-bit for full RAM utilization.
• RAM issues. Windows may fail to use all RAM if a section of it is faulty and rendered unusable.
• Outdated BIOS. An outdated BIOS may significantly impact how your RAM works.
