    Hello everyone

    I have recently purchased an ATI Radeon HD 5770 for my Mac Pro 1,1. Under OSX (10.6.8) it works just fine, quiet as a mouse. Under Windows 7 64-bit, however, it's a different story. The fan on the graphics card seems to be putting in a lot of extra effort, it's actually quite loud and distracting.

    I have installed Bootcamp 3, or rather, the version that comes with the retail version of Snow Leopard and generally everything is working perfect, even though technically the 64-bit version of W7 is not supported on this model.

    Looking under the Screen Resolution properties I am only given the choice to go up to 1152 x 864 so clearly something is amiss here.

    My question to all those out there is am I able to update these drivers direct from the manufacturers website without screwing anything Bootcamp-related up? Will that even help reduce the fan noise?

    Thanks for your advice.

    Definitely sounds like a driver issue. I can see no harm in installing the Windows drivers from the manufacturers website.

    Though, make sure the card is seated properly/receiving proper power/has right drivers. My GTX 660 was having similar issues last week, and now it's in the mail for replacement by EVGA.

    Hello both

    I have just upgraded the drivers for my 5770 and it went smoothly, no issues so far. The fan noise is so much better now and the screen nice and sharp.
