question about sli, number of cards reported

[jmartin357]

ok, I need a bit of help. I bought a new pc from one of the custom shops and that all went pretty well. booted up and everything appeared to be working.

2x evga 980ti (hydro copper in a liquid loop).
(1 evga sli bridge connecting those)

asus maximus hero viii
6700k (also in the loop)
32 gigs of corsair 2400.

windows only reports 1 card. digging a little deeper, gpu-z only reports 1 card. digging a little deeper, my motherboard tells me it only has one card plugged into the top slot. both cards light up a little bit, but there are no fans, just the liquid cooling.

if I plug my monitors into the top card, everything is cool. the second card does not output video.

so, here's the question, which may be silly: does sli report as 2 cards? or is one a slave to the other and sort of hidden? or, as I suspect, is there something wrong with this setup and only one card is working?

Thanks for your thoughts!

You should see the card whether SLI is working or not. I had a similar problem with one of my setups, and it turned out that the motherboard was bad. It could be the 2nd card also. Since you got it from a shop, id take it back and have them look at it.

Do you have both cards enabled in your Nvidia software as SLI?

Open up the Nvidia Control center and make sure SLI is enabled.

I don't see anything in the the nvidia software about this being sli. for example, when prompted about physx it just says it will figure it out. when it displays what's plugged in, I can see both monitors into the back of one card, and no other cards displayed.
