    Following on from my previous question, this was the information I was given ...

    "So in order to be able to run Windows 10 (or Windows 8/8.1), you need a processor that supports PAE, NX, and SSE2. Without this, your Windows 10 fun comes to an end.

    PAE gives 32-bit processors the ability to use more than 4 GB of physical memory on capable versions of Windows, and is a prerequisite for NX."

    Does that mean 32bit processors can run 64bit Win 10, and use 8GB RAM but my 64bit processor can't use 8GB on Win 10 32bit?

    I'm confused!!!

    Please create an account and actually reply to your original thread to maintain continuity and keep things relatively clean next time.

    32-bit processors (older ones) simply cannot run 64-bit Windows.

    64-bit capable processors can run BOTH 32 and 64 bit installs of Windows.

    64 bit installs of Windows are required to handle more than ~3 GB of RAM.

    In short, if either the processor only supports 32-bit or the Windows is 32-bit, you aren't going to be able to use 8 GB.

    In the former case you'll need a newer processor which probably entails a newer PC. in the latter case you will have to reinstall windows with 64 bit installation media.
