    I was able to install Vista 64 bit SP 1 onto my iMac 3.06 GHz, and I was actually able to install bootcamp on it as well, but the nvidia drivers weren't installed. I tried going to and finding the drivers, but the drivers didn't recognize the hardware on my computer so it couldn't install it. If some one can help me get the drivers on my computer it would be much appreciated.

    pardon my ignorance

    I don't own an iMac and cannot help... sorry. But I am wondering how you got a 64bit version of Windows installed. I didn't think that the iMac was even a 64-bit computer. Nice to know...if true. I assume you tried the Nvidia site???

    Best wishes with the drivers.

    Anyway, Try getting the latest beta drivers from nvidia. That's what I had to do to get the 1st gen mac pro 8800gt to work when it first came out.

    This post should tell you everything you need to do. It's discussing installing 8800GT drivers for the Mac Pro, but since the GS and GT are exactly the same as far as drivers are concerned, it works fine for the iMac as well - worked perfectly for me on your exact machine a month or two ago.

    Oy. It continues to amaze me that Apple blissfully ignores this 64-bit driver problem. Hopefully Snow Leopard will end that.

    Actually, the latest Mac Pro bootcamp drivers do come with drivers for the 8800 GT - the problem only persists with the iMac because Vista 64 isn't officially supported on the iMacs.

    8800gs driver installation - Vista 64-bit

    Hello. I have a 24" iMac with the 8800gs video card. I'm running Vista 64-bit using bootcamp. I've found a way to install a driver and get it working for the video card.

    1. Download the latest Nvidia GeForce Driver for Windows Vista 64-bit.
    2. Run the exe file. It will fail, but the purpose of this is to create the C:/Nvidia...etc folder that contains the driver.
    3. Now open your device manager. If you're a little rusty, that's Start, Right click on computer, properties, device manager (on left)
    4. Navigate to the 8800gs graphics adapter under display adapters (it may not be called 8800gs yet)
    5. Right Click and update driver.
    6. Select Browse my computer for driver software.
    7. Select Let me pick from a list of device drivers on my computer.
    8. Select Have Disk and then browse to the location that was made in step 2. This is usually something like c:/nvidia/drivers/.....vista64bit.
    9. Then scroll down and select the 8800gs driver and install it (this may take 2 or 3 minutes)
    10. Restart and you're finished!

    I now have a 5.8 rating in the Vista performance tool. Sweet!

    video issues

    Hi All,

    I have followed the procedure to get the 64bit Nvidia drivers working in Vista under bootcamp. I can get the drivers to install, and I get Areo working, my performance in games is horrible. Half Life 2, which should run fine on this hardware drops frames and cannot be played, and I won't even mention Crysis. I know this isn't the fastest video card around, but it should handle HF2 without any issues. I also get some strange anomalies when playing back video as well.

    The reason the Nvidia drivers do not pick up the video card is that Apple is using the laptop version of this chip, and Nvidia does not provide drivers directly for their mobile hardware because OEM can tweak the chips to their exact specifications for laptops. I had an old Dell with an Nvidia chip, and again I had to get the drivers from Dell.

    I am assuming Apple chose to use the Mobile version of the chip due to heat issues and what not.

    From Wikipedia:

    The 8800 GS has 96 stream processors and 384 MB of RAM and 192 bit memory. In May 2008, it was rebranded as the 9600 GSO in an attempt to spur sales.

    On April 28 2008, Apple announced an updated iMac line featuring an 8800 GS with 512MB of video memory. However, the card is actually a rebranded NVIDIA GeForce 8800M GTS. It features up to 512 MB of 800 MHz GDDR3 video memory, 64 unified stream processors, a 500 MHz core speed, a 256-bit memory bus width, and a 1250 MHz shader clock.

    It sucks that they are using a mobile version of the chip and you lose 32 stream processors.

    Anyways I might go back to 32bit Vista. There is really no reason other than Crysis to run 64bit right now. Hopefully Apple will correct this issue soon.

    According to my system information on my iMac, the 8800GS is also a PCI Express x1 video card. Which is strange, because it should be a PCI Express x16.

    Isn't this what the ATI Radeon 2600HD Pro runs at? 16x?

    I just downloaded the Mac Pro 64-bit installer. The only thing that didn't work were the Intel GMA drivers which I just download from Intel anyways. This is going Boot Camp 2.0.1 on Vista SP1 and then upgrading to 2.1.

    The 8800M GTS is a 16x card. Is this under System Profiler?

    Yes... the bus is a PCI Express x1, NOT a 16x
