Do u use vista 32bit or 64bit software with bootcamp 1.4?

I just got a mac pro and need to use older pc software and will load vista.
macpro is 64bit computer but the bootcamp 1.4 manual says for XP use 32 bit software. Is this the same for Vista, or can I use 64bit vista software?
Many thanks

Bootcamp only supports 32bit windows and while you are correct that your computer is 64bit and can run Vista 64 its generally not recommended.
First the only real advantage to running 64bit windows is you have access to more ram. The downside is that unlike 32bit windows, 64 bit will only install Microsoft Signed drivers. This can be accomplished by searching the net, but until you get them all your computer will have less functionality.
Third (I cannot confirm this since I don't run 64bit vista) is that 64bit windows reportedly has issues running games and such.
Bottom line, problems with getting the drivers, running games just for a more maximum ram means little advantage to going that route.
Just my $.02

  • Windows Vista 32bit or 64bit?

    Which is better for my new mac book pro, Windows Vista 32bit or 64bit Ultimate? All I care about is all of my programs and games working properly. And what does 86x mean? Will one version of the bits work faster than the other?

    Hi Konnexion,
    There is another more important limit with 32-bit versions of Windows, and that is the limit of 2 GBS of RAM per process. Unless some tricks and tweaks are used (which can result in reduced stability), no matter how much physical RAM is installed, a single application can't use more than 2 GBs. This is important for applications that can use large amounts of RAM like video and picture rendering apps, and even some games these days (particularly in Vista).
    On the other hand, the 64-bit version of Vista has a number of additional security enhancements over the 32-bit version, such as address-space layout randomization, mandatory driver signing. If you have the RAM (at least 4GBs) and games are not a priority, I would actually recommend using the 64-bit version. Of course, why would you be using Boot Camp, if it weren't for games LOL?

  • Vista 32Bit or 64Bit?

    Hi,
    Has anyone got any suggestions and some advice on which version of Vista is better, 32Bit or 64Bit and why?
    My T500 has 4GB memory, but this is the maximum, at the moment, not sure if this will change when the 4GB SDIMM's will be realeased.
    I've currently got Vista Business edition 64Bit installed on it but I'm having issues, not sure if it's me or the software, but would like to get some input from those who have 32Bit and 64Bit version of Vista on their T500.
    Thanks in advance,

    I've tried XP Pro, Vista Ultimate, and Vista Business 64 on my T400.  I ended up sticking with the 64 bit OS since with the switchable graphics option and the limits of a non-PAE 32 bit OS, I only had 2.5G of RAM available with 3G or 4G installed.  With VB 64, I get almost 4G usable which I need for the virtual machines I run.
    I have been able to get (almost) all of my apps to run, and once I got the wifi sorted (by downgrading to the 5100 card) it has been quick and stable.  So far...
    YMMV

  • Changing Vista 32bit to 64bit on Satellite A500-14Q

    Please let me know if I could upgrade my operating system from Windows Vista Home Premium (32bit) to Windows Vista Home Premium (64bit).
    I've initially configured the laptop to 32bit and as this has a RAM of 4GB, I need to know if I could upgrade it to 64bit so that I could upgrade to Windows 7.

    Hi
    The recovery procedure doesnt take a long time Maybe 15 to 30 minutes. I dont know it exactly. I only make few clicks to start the procedure and then I drink a coffee. ;)
    The advantages of 64bit system Well mate, I think its the support of 4GB or more RAM. On 32bit system you can only use ~3.2GB. Thats all!

  • HP Pavilion 15-p229ax using windows 32bit or 64bit ?

    Guys, anybody know about the OS of my laptop (HP Pavilion 15-p229ax AMD) ? 32bit or 64bit ? 

    Hi: I recommend you install a 64 bit operating system.  It will be easier to find drivers for it and if you ever want to add memory you will be able to, since with a 32 bit operating system you are already at the max.

  • Use Windows Server 2003 or 2008 with BootCamp?Just want to run basic things

    Hey, well I can get a copy of Microsoft Windows Server 2003 and 2008 with the DreamSpark program (as I am in college) for free. But my question is, is this a good idea to use with my MacBook Pro? I wasn't sure how well it'd work with Boot Camp, and all I'd want is to just run basic programs and/or games.
    Is it a good idea? And does anyone have tutorials for how to install it?

    Hi,
    Windows Server 2003 and XP 64-bit share the same codebase and XP-64bit is not supported with BootCamp.
    Windows Server 2008 and Vista 64-bit share the same codebase and Vista 64-bit is only supported with BootCamp on some Macs. See here: http://support.apple.com/kb/HT1846
    For running 'basic' things with the Server versions, why not use one of the Virtualization apps like Parallels, VMWare Fusion or VirtualBox ?
    http://www.parallels.com/products/desktop/
    http://www.vmware.com/products/fusion/
    http://www.virtualbox.org/
    VirtualBox is open-source, so you don't have to pay for it.
    Regards
    Stefan

  • I need all windows vista drivers on imac20" leopard with BootCamp

    Hi Dears,
    I have formatted my windows vista on my imac20" and I installed windows Vista again but I found that I don't have sound in the system and the video quality became worse than before, and I can't type in arabic, So I need all the drivers for it to work again as before,
    sound, video, keyboard ( I have Multilingual keyboard Arabic & English ),
    and what ever drivers you guys think that I will need..
    Thanx & Regards

    You can find people here, where even AFTER installing Apple hardware support, they still had audio problems; needed graphic drivers.
    Glad it works fine, I'd reserve "perfect." Boot Camp 3 has trouble with the AppleHFS if you look around.
    I've heard so many stories of support advice, and I doubt unless they work with BootCamp and Windows on Mac fulltime they know all the ins-outs.
    64-bit versions of Vista/7 are still not getting Apple official support. Have to see if the newest iMac changes that, would be a crime, now that it can easily be outfitted with such niceties as 8GB, better graphics, Core i5/i7.

  • Vista 32bit or 64bit for video games

    I installed vista 64bit on my macbook pro and I'm trying to play ea sport games like fifa 2009...
    I notice that there is some performance lags during gameplay....
    would there be a difference if I installed the 32bit version of Vista instead?

    How much memory is installed?
    Have you - or are you able - to update the graphic drivers?
    Windows 7 (now build 7057) is much better than any version of Vista. Otherwise, XP has a smaller footprint but can't use more than 2GB.

  • Problem with printing checks from quicken 2004 - using Vista (32bit) and Officejet J6480

    I have used my quicken 2004 version with my old XP with no problems and HP officejet J6480 All-in-One.  Just got a new computer and everything was going great until I went to print checks - it prints one line and then stops printing.  I assume the problem is with the Vista - is the Quicken 2004 too old?

    Hi , Welcome to the HP Forums! I noticed that you cannot print checks with Quicken, when using your HP Officejet Pro 6830e all-in-one on iOS. I am happy to take a look into this issue for you! Some questions for you: What version of iOS are you using? If you do not know the Operating System you are using, please visit this website. Whatsmyos.What happens when you try to print in TextEdit?Are you able to make copies with the printer?

    BTW:
    You perhaps can install Audigy 2 drivers and software to your card. Here are the instructions how to do it.
    It's quite easy process. Download Audigy driver/software package (~20MB) (link is there), extract it into some directory. Download the patch (link is on Automatic Method sentence)and follow instructions how to patch the instalation package. Then installation process. I've modded my Audigy 2 to Audigy 2 Zs using a similiar method and everyting else, but GraphicMixer, works great.
