Normally a 32-bit system (x86) can support maximum of 2.75 to 3.25 GB of RAM (depending upon your system configuration) even if you are having 4 GB or more RAM. A 64-bit system (x64) can support up to 128 GB of memory. This is because Windows doesn’t allow users to use more RAM in 32-bit due to licencing issues. Here i’m going to show you how to bypass this issue and use 4 GB or a
