Ok yes, im that guy that was really exited about getting a second HD4850 to make a crossfire set and now I am majorly frustrated. Turns out I got my card today in the mail.
Well I did acomplish one thing, which was lowering the temperature on the card by intalling the ZALMAN VF1000, now my idel is a 40C! i love it. Shortly after im done with that I install the second card along with this one in my system.
A long story short, after Vista intalls the new VGA adapter, I reboot. Then when Im booted back I go into ATi Catalyst and very anziously waiting for it to load and... to come to my surprise, there was no crossfire option under the Overdrive option.
I have done some research online and the issue most people are having is with Vista 64-bit, which is the one I have so thats not good to hear. One thing I did hear is to revert back to 8.11, I did. Nothing. and the final thing I heard was an 8.12 hot fix. Tried it. Nothing. Now im stuck. I think I have 3 possible things that could be wrong.
- Software drivers
- I have to activate the 2nd PCIe 2.0 on my board
- too much RAM?
I read up on the last one while on the research, idk...
Another thing you guys should know is that when I look in the "Information option in Catalyst, I click on "hardware" and It comes up with "primary adapter" and it list the specs of one of the 4850's. Below it there is another that says "disabled" adapter, however it is not disabled in Device manager.
What do you guys think?
