Upgrading To 8800gt from 7600gt

So what's the best way to do this? Do I just pop the 7600gt out, put the 8800gt in, start up the computer then install the 8800gt drivers? Or could the 8800 drivers conflict with the 7600 drivers? Or do I install the 8800gt drivers, take the 7600gt out then put the 8800gt in? If I uninstall the drivers, remove the 7600gt then put in the 8800gt will windows detect the 8800gt or do some kind of nvidia drivers need to be installed first?

  1. Yeah, you are generally advised to delete the 7600 from your computer before you take it out. Then you can slot in the 8800 and windows should pick it up. Then just install the drivers from the CD and you are laughing.
  2. While the 7600 is in:

    Go to your device manager and uninstall the drivers for the 7800. It may ask you to restart, just tell it "no" and shutdown. (It is advised to use something like Driver Cleaner Pro to completely remove the old 7800 drivers)

    Remove the 7800 / Put the 8800 in (make sure you connect the extra power adapters) and boot up. It may say "new hardware found - blah, blah, blah" Tell it not to install it and that you have the disc. Install the latest driver from the manufacturer site, restart, and you're now good to go.
  3. Ok thanks for the help, I just have one more question. Will my 550 watt Antec Truepower2 PSU be able to handle a 700mhz core 8800gt (limit is 19A on the psu)? Also, looking in speedfan the +12v rail is at 0v, is that because I'm not using anything that uses the +12v rail? My -12 volt rail is at -16.97, is this bad? And how do I see the amperage of each rail, is there a way to do that in speedfan?

    Check the side of the PSU. There should be a sticker that lists the specs.

    Found this:



    Looks like 19A on the +12v, so that should do just fine for a single 8800.
  5. Ah, I edit right as you post, lol. How do I see what I'm currently using for amperage now that I know the max? And do you know the answer to my -12v rail being at -16.97v? Is that supposed to be like that?
  6. I think SpeedFan is reading it wrong. It the +12v should be at like 11.8-12.0v. You can try going into the BIOS and checking the hardware monitor. That should tell you what your +12v rail is capable of.

    As for the amperage, I'm not sure how to check how much your system is currently using. You could just check individual parts you own and see how many amps they recommend if you're worried. I don't think it will be a problem though.

    Ok, thanks for all the help.
  8. A 550W Antec should power your setup. Don't put too much trust in SpeedFan, or for that matter any Windows based voltage monitoring application. Your BIOS is the best place to look for voltage readings unless you have a good old-fashioned multimeter.
  9. The Antec TP2 550w has dual 19 amp rails and a max combined of 36 amps. it will power any single gaming card out now, and easily the 8800GT.

    But yeah, make sure to at least remove the "Nvidia display driver" from within control panels "add/remove programs" before shutting down and removing the 7600GT. If you want to go a step further with driver cleaner, better yet.


    edit: lol didn't see the PSU pic before posting. :)

    Agree, except would not go to "manufacturer site" for drivers. You are not likely to get the latest as many of these sites are not timely updated. Go directly to Nvidia for drivers and installation instructions if you want the latest.
  11. yeah I always go right to NV's site too.
