asmoore Posted December 15, 2005 Posted December 15, 2005 Just built my rig using the parts listed in my signature. Purchased 2 7800GTX for an SLI configuration. However, I've attached the bridge and followed instructions according to the DFI manual and the board recognizes both video cards. Yet, when I go to configure SLI under nVidia settings it gives the following message: "You must remove any graphics cards that are not compatible with Scalable Link Interface Technology before you can enable SLI" Both cards are from the same manufacturer, and they are both fully opperational. Both cards are manufactured by XFX. I've downloaded the latest card drivers along with the nForce driver that came with the mobo. Does anyone have any explanation as to why I am receiving this error?

chupa320 Posted December 15, 2005 Posted December 15, 2005 do you have your sli jumpers set correctly? try one card, with sli enabled, turn on boot into windows. next shut down, install the other card and boot again. See what happens Share this post Link to post Share on other sites More sharing options...
Evancold Posted December 15, 2005 Posted December 15, 2005 do you have your sli jumpers set correctly? try one card, with sli enabled, turn on boot into windows. next shut down, install the other card and boot again. See what happens The Expert board does not have the SLI jumpers. Do you happen to have the bios settings changed to run SLI? Share this post Link to post Share on other sites More sharing options...
Reinvented Posted December 15, 2005 Posted December 15, 2005 The Expert board does not have the SLI jumpers. Do you happen to have the bios settings changed to run SLI? The board might not have jumpers, but an easy way to eliminate the problem is to definitely check the video card bios. It's becoming an issue now. People are getting a 2nd card further and further apart from the first purchase date, and by then the manufacturer will have a different release or what not. Give XFX a ring and see if they can help you determine what bios you are using and if you can RMA them for a pair that will work in SLI. I believe you'd only get that message if in fact your cards have a minute difference such as that. Share this post Link to post Share on other sites More sharing options...
Cyberparasite Posted December 15, 2005 Posted December 15, 2005 ok, how do you explain people running cards from 2 different manufacturers on sli mode if indeed it is the card bios that is the problem? Share this post Link to post Share on other sites More sharing options...
Reinvented Posted December 15, 2005 Posted December 15, 2005 That's a driver implimentation right there. Two vendors, not a bios problem. This guy's problem is from ONE vendor, not two different ones. Share this post Link to post Share on other sites More sharing options...
gr8golf Posted December 15, 2005 Posted December 15, 2005 I have another thread with pretty much the exact same issue - only significant difference is the card manufacturer. Maybe we should merge them? Share this post Link to post Share on other sites More sharing options...
gr8golf Posted December 16, 2005 Posted December 16, 2005 Also - for you peeps that have SLI running with the Expert, what Expert BIOS are you using? Share this post Link to post Share on other sites More sharing options...
asmoore Posted December 19, 2005 Posted December 19, 2005 I'll mess around with BIOS abit to see if that could be the problem- however, I don't think that would be causing the SLI compatibility issue. Does my board fully support 7800GTX vid cards? Share this post Link to post Share on other sites More sharing options...

Reinvented Posted December 19, 2005 Posted December 19, 2005 Contact XFX, because they will be able to flash your cards to the same bios so it'll run fine in SLI. Share this post Link to post Share on other sites More sharing options...
