turn off sli

Hello everyone,
Here is my problem. I have an A8N-SLI deluxe MB. with two ATI x800pro's. I want to run dual cards, non SLI, with 3-4 displays. Both cards work. When I put then together the system only see one. I have the bios set to dual card and have tried the auto setting too.
The SLI card has been turn to dual card,and you cant use the bridge withese card.
OS is XP Pro 32bit.
I have read different blogs, and they say that it will works, the band width will just be split x8 and x8 and it acts as two seperate slots.
The one thing they all say is to turn off SLI..... Where and how do you do this? I know if they were Nvidia board you could do it in the Nvida control panel. But since it is ATI cards no NCC. The ATI CCC just show the one working card. Is the CCC causing the problem? Should I just load the driver and not ccc and use windows to set up the displays?
Any help would be great THIS IS DRIVING ME CRAZY

Ati does not use SLI, but crossfire. I believe your board doesn't support crossfire, only SLI.
 
what version of ccc are you using? those are old cards. You should be able to just set it up with windows.

Your cards always run in non-sli. That is nVidia talk for dual gpu. Ati's version is called crossfire. Secondly, X800 pro's aren't capable of crossfire so you don't have to worry about turning it off
 
Why is it only finding one. should I deletet CCC.
The CCC is for legacy products
When you go to ccc it shows one display as primary and the other is secondary, but both on are on the same card.
 
I think you need to flip the SLI switch key on the motherboard to enable both PCI-e graphics slots. Try it ( I have a hunch it will work). Failing that then the others above are correct, your board will not support 2 cards from a non-nVidia manufacturer.

The switch key looks like an so-DIMM for laptop memory it has "normal mode" printed on one side, going by the photos I have seen. It was a particular quirk of this series of motherboards as later boards simple detect howmany PCI-e slots are populated and act accordingly. HTH
 
I did switch it to dual. Made its not seated well. Will check that tonight.
When it is on dual and they are nor SLI card they should work as seperate lots, just the band width goes from X16 toX8 each.
 
Well thanks to all the that helped. I did get it working. The two things I did was to reinstall the E-Z select card and change the 3rd monitor to the DVI plug.
Thanks again
