  • Windows 7 32-Bit With More Than 4GB Of Memory

    Is it true that if I want to install more than 4gbs of ram I need to switch to windows 7 64-bit?

    Thanks

    It is true that if you want to use all of your 4gb of ram or more, then switch to x64.
    My local hospital has a sign which reads "This way for accidents and emergencies." Haven't people in hospital got enough to worry about without looking for further misfortune?

        In a word,yes.

        You can physically install more than 4GB of ram in a 32bit operating system pc but it will be wasted as the os will only use about 3.5GB.

        So for anything over 4GB you need a 64 bit os.

          Even worse than above, the total memory allocation for a 32bit Os is ~3GB and that means if you have a modern GPU which often have 1GB RAM onboard, then an absolute maximum of ~2GB of system RAM will be available.

            RAM is counted after all the other memory is counted, so GPU, CPU cache etc. will all add up and remove the total amount of RAM available on 32bit.

                Not quite true - Generally, the rule of thumb for consumer versions of 32bit Windows is the maximum memory is 4Gb. So with a 1Gb Graphics card, you'd see 3Gb of RAM.

                Although there are 32bit versions of windows that can support up to 128Gb, but thats a whole other discussion

                    Doesn't address it in the proper sense and is server only.

                        As Invader says, its the server software which is able to address more than 4Gb, when PAE (Physical Address Extension) is enabled too..

                        Let me do some digging for the relevent info..

                        EDIT:

                        Windows RAM Limits across all operating systems:

                        What PAE is and how it works (And why the Operating System still doesnt address more than 4Gb RAM properly)

                          interesting links, wonder why win 7 home permium is limited to 16gb whereas the pro version can take 192, sounds like a sales ploy to me

                            Also not quite true as I have a 4870 1GB card and have 4GB of ram
                            and have 3.5GB of usable memory

                              You are quire correct, sales ploy. Also why would a home user actually want more than 6-8 gb?
