    Er, no? It can't be done. For all sorts of reasons.
    Unless you can show me software that can physically redesign the CPU, I'm going to say it's impossible.

    (There are a bunch of tweaks that can be made to sort of get closer to this, but none are without their disadvantages, and generally the cost is paid in system instability)

    Try to add /pae in the boot.ini, it worked for windows server 2000+ 32bit to utilize more than 4gb of installed hardware memory. Never tried it on a Desktop OS yet.

    You didn't tell us what OS you are using. /PAE might work on XP, 2000, but it doesn't work on Vista. /PAE also might cause bad instability if used on the older windows

    /PAE may cause instability on every Windows. Because it's an unusual setting, that not all drivers may handle correctly.

    It wasn't causing instability on windows 2000 and 2003 running SAP R3 24/7 in 3 years for a major company I've been to.

    You can read the Microsoft documentation for more details.

    I think what you meant to say is, " I have not seen it causing instability on windows 2000 and 2003 running SAP R3 24/7 in 3 years for a major company I've been to, but you might see different results".

    The problem with /pae is that drivers need to be written very carefully so they don't cause the system to crash. A server company would put much effort into this and a lot of testing, but I would not expect the same effort from every desktop company.

    What orev said.

    Of course, it may not cause any problems, but just because *you* haven't seen any issues with it doesn't mean that none exist. Have it occurred to you that the company you worked with for 3 years may not have been running a representative sample of *all* hardware and software that people run on Windows machines?
