If less than 4 GB of memory is showing in a 64-bit system, what should be done?

Upgrade the RAM
Install a 32-bit version of the operating system
Install a 64-bit version of the operating system
Increase the page file size

The correct answer is: Install a 64-bit version of the operating system

In a 64-bit system, it is designed to handle more than 4 GB of RAM, which is a limitation of 32-bit systems. If less than 4 GB of memory is detected, it is essential to ensure that the operating system installed is indeed a 64-bit version, as a 32-bit OS cannot efficiently utilize RAM beyond the 4 GB limit. Installing a 64-bit version of the operating system would allow the system to fully recognize and utilize the installed RAM, assuming that sufficient physical RAM is present. This upgrade is crucial because the architecture of a 64-bit system can address larger amounts of memory, vastly improving performance and allowing for better multitasking capabilities. In summary, to address the issue of less than 4 GB of memory showing on a 64-bit system, ensuring that a 64-bit operating system is installed is the key step needed to take full advantage of the memory capabilities of the hardware.
