The BIOS recognizes 12GB of memory, but the Windows 11 system only displays 4GB.

After adding 8GB of RAM to the original 4GB, the BIOS shows a total of 12GB. However, Windows 11 (23H2 64-bit) only recognizes 4GB. Even after reverting to the original 8GB configuration, the system still only displays 4GB. Please provide a solution.

    Limited memory for some weird reason? Check 

    • Press Win + R, type msconfig, and press Enter.
    • Go to the Boot tab → click Advanced options.
    • Uncheck the box for Maximum memory.
    • Click OK, then Apply, and restart your PC.
