Hi, 1st of all id like to say that my level of knowledge in computers is rather low so dont be surprised if some of my questions sounds stupid or if im slow to understand.

Here it goes... so today i decided it was a good time to format my hard drive and reinstall everything so i started by reinstalling windows(without updating it so far), after I installed my wireless card drivers and then downloaded the lastest catalyst version(9.9). thats where the problem starts... so in my older version of catalyst, there used to be a tab in the menu called "crossfire" where i could enable/disable crossfire and now theres no crossfire tabs so I downloaded older versions to c if it was just because the new drivers didnt work for me and it didnt show up either. I checked in the device manager and it detects 2xhd4850. So far, i've tried to reinstall everything, install service pack 2(i have vista 64 bits) download updates and it still doesnt show up.

Well i think that sums my problem pretty much...

Thanks in advance for the help

PS: if anymore information is needed just let me know.

Does this help?






EDIT: As I read again it looks like I misunderstood your issue, have you tried running GPU-Z and seeing if both cards show up there?

It shows both of my cards in the device manager. When you run gpuz can you click on the little bar at the bottem and switch between both of your cards, and if so do they both show up correctly?

Yes the crossfire tab is in all versions, the device manager shouldn't say anything about crossfire it should just show your GPU's.

completely unistall you current driver and try an older version of catalyst, like 9.6 and see if that changes it.

I honestly don't know, I don't suppose you have another computer that you can try the card it to see if it works?

Hey try un-installing the CCC again... boot into safe mode and run driver sweeper... reboot...now power back down and remove the second gpu...power back up and install the driver.... once thats done power down again and install the 2nd gpu and dont hook up the x-fire bridge.... boot back up and see if the 2nd gpu is showing up in the device manager.... if it does than power down and install the x-fire bridge... it should now work for ya... good luck :toast:

2nd card? crossfire bridge? he's a 4850x2, single card

the only reason he even has that menu is cuz of the 4 dvi outputs, in order to use all 4, one must disable CF (on my 4870x2, there is no CF tab in CCC)



anyway, i think you should have done windows updates first (SP2), then driver install

any reason you wanna disable CF?

It would be nice if he filled in his system spec...
Also we had the impression he was using 2 single gpu's WOW :shadedshu
