  • Windows 7 32 bit or 64 bit?

    Hey guys,

    I imagine this question has been asked a few times before, but my case is a little different.

    I have a motherboard here with 4 GB of RAM that will only allocate 3 GB on Windows 7 32 bit. I guess thats because of UEFI.

    If I had 3.5 GB or so I would take 32 bit without question, but I'm not sure if 3 GB will be enough since I will be recording 720p and maybe 1080p later and have quite a lot of background programs.

    I tried once using 2 GB and only had 700 mb free and that was without any background programs open and not recording.

    On the other hand I also am concerned with the compatibility of some drivers and applications when running 64 bit Windows. I had some issues in the past, but I am not sure if they were related to 64 bit.

    So, should I stick with 32 bit and only 3 GB or should I go 64 bit?

    Any suggestions and help are appreciated.

    Thanks in advance.

    Just use the 64. Drivers are not much of an issue anymore. I have 64 on 2 desktops and a laptop with no issues. I run 32 in the car because it is a netbook with 2gb of ram. (hindsight almost says I should have used 64 as my desktop that I do test builds on is 64 and I have to tweak skin files to take out (x86) from the end of program files path all the time)

      I am using only 32 bit applications anyway. I also have not measured a difference in performance when using a 64 bit codec compared to a 32 bit codec when recording my camera's feed.
      However, I had some problems with RBC9 (which I dont use anymore, but still) and with XPort because they either dont have any 64 bit support or it simply sucks. It all worked more or less, but it was patched together with many tricks and additional software to make it work, and thats why I am concerned about stability. Also because of the performance drain of WoW64 emulation.

        Tried both. Less driver issues with 32bit.

          I would go with 64-bit, but as an aside, I wouldn't worry to much about how much RAM you are showing free without any programs running. The memory management of Windows 7 is much better than old os's such as XP. Free memory is wasted memory, so what Windows does now is make use of as much Memory as it can, preloading commonly used items into RAM. This helps make the OS feel much snappier, and since that RAM is otherwise sitting unused, is a good use of RAM.

          As soon as a program requires more RAM than is available though, Windows will release some ram back to the program to allow it to run. Once the program is done with the RAM, windows will fill it up again to keep the OS feeling snappy.

          This way, it always looks like you are maxing out your RAM, but in reality your OS is just making use of unused RAM, and is doing a better job at managing what it uses vs. what other programs use.

            Forgot about xport. If you are going to use xport... definitely 32.

              Well, I dont have to use XPort. GPSGate works fine on 64 bit.
              As I said, my main question was about 3 GB being enough for what I have planned.

                It depends on the background programs you are going to run. The recording should cache an amount to the memory then feed the rest to disk. I'm assuming you meant you had the recording software open but it just wasn't recording. It is possible it had already carved out the cache space. Right now on my 64bit win7 with 4gb, I show 1gb used, 2802mb cached and 177mb free. This cached memory will page VERY quickly if you start needing it for something else. In my case this workstation has been running for 4 days so there is a lot of stuff like photoshop and vs.net in that memory waiting to be called on or re-allocated. All that to say, 700mb free doesn't mean much unless you mean 700mb available... then it means more.

                My guess is that you will be fine with 3 gb and 32 bit.

                    32bit.. 64bit is still not supported in all the required ways....
                    There was one software package that was still buggy on 64 as in you needed to run 32bit version... I Believe this was flash or something...cant recall honestly
                    Been awhile...

                    And losing support for 16bit is a concern to some people.
                    Otherwise you should be ok using it.. But for myself i choose 32bit in the office and outside..

                    Only a games machine or a high end number cruncher i would use 64bit for.

                    to myself, 64bit is still a few years away from being mainstream in my business

                    From the java site:
                    SUMMARY
                    64-bit Windows operating systems (which may be Windows 7, Vista or XP) come with a 32-bit Internet Explorer (IE) browser as the standard (default) for viewing web pages. These operating systems also include a 64-bit Internet Explorer browser, however using it is optional and it must be explicitly selected to view web pages. Note that because some web content may not work properly in a 64-bit browser, we recommend using the default 32-bit browser and downloading 32-bit Java.
                    While the 32bit will work on a 64bit system, This only strengthens my argument that 64bit is not yet complete....

                      32 bit, 64 is fine for desktops etc but for a carputer running some hobby based programming you may will have issues and will always wonder is it because its 64 bit? when any challenges arise.
