Hello,

Specs:
Intel Q9550
OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
GIGABYTE GA-EP45-UD3P (up to date firmware F9)
Visiontek 4850 (two)
600 watt PSU antec


My problems started when I first built the computer with windows xp which was when I ran xfire while playing an online game to stream I would get a BSOD most of it had to do with some ati related file. I tried updating drivers I would get the same thing. So I didn't think much of it since I was able to play games.

Yesterday, I just upgraded to window7. I tried downloading the driver off amd.com for win7 64bit+4800 series during near completion of the installation of the driver it would fail on installing. Thus I can't not activate crossfire. I tried using both cards as singles and I was not able to install the driver. I was able to install the "windows update" version of the ati driver update but it doesn't have the controls to activate crossfire.

So currently I am running on a single card with massive BSOD (~10 today) usually (5x) it would be during game play. One of the BSOD I saw pci.sys seemed to be the issue.


thank you.

This question requires a very long explination,... i direct you to an article on anandtech about 1+ yrs ago about crossfire. The short answer it that one must install the cards, the driver and then enable xfire. If you are going to change anything you must disable xfire and then excute, example update the driver. Do read the anand tech article it will tell you how to fix your system.

Well that is what I did... since I built the computer myself. I added both 4850s and then installed window and then the driver for it for windows XP.

However for Windows7 I formatted and then instaled windows7 using their ati driver. I tried updating it but it would refuse.
