SlI problems

MountainPro · January 23, 2015

Hey everyone,

I have 2 GTX 780's one from EVGA SC series and then a PNY enthusiast edition. I have done research and these cards will work in SLI but my mother board is not recognizing the new card. When the card is plugged in my first GPU will run at 8X but there will be no other card "reported" being connected to the board.

I have an ASUS Maximus VI Formula it is SLI ready but I am very confused on how to fix this issue.

Thank you,

Josh

Connected the SLI bridge?
Updated the drivers?

In Nvidia control panel, does configure multi gpu tab show up and display both cards?
Does the new card work if you swap it to the primary single card?

I have yet to try the new card alone that is what I will be doing this weekend when I get home from school. and Yes the SLI bridge was connected but it was the one that came with the mobo so I was not sure if I connected it correctly. and no it dose not come up in the control panel

Take out your first card and test the second one by itself to make sure it isnt doa

OK, thank you. I will try that as soon as possible I am not new to building PC's but have never done any SLI builds. If the card isn't DOA are there other things that I can test to see if it is the Mother board?

If the card isnt doa then i would test the new card by itself in the second slot (the one you would be using for sli) Provided the slot is in good working order then you will be able to boot normally and the card should be properly detected. If it is detected at that point then I would give it another go with sli and hope for the best. It may be possible there is a defect in the board (very unlikely) That its having trouble enabling sli with both cards installed.
