Have you made sure the drivers are installed on all 4 cards?

Could you list your hardware please, I am assuming you are on the Rampage IV Extreme but just want to make sure.

Thank you do not want to presume.

Your configuration is interesting (should make no difference of course) is there a reason for the position of the two cards in slots1and 4? And is the problem present regardless of where the cards are positioned?

[Tomeczek]

The situation looks like this:
Slot 1 plus slot 4 (the only setting where we have 16x and 16x)
Quad SLI does not work.

Slot 1 plus Slot 2 (16x and 8x)
Quad SLI is working properly.

I ran out of ideas.
In the case of 16x and 8x do not lose at maximum efficiency?
It will be a significant decrease fps?

[HiVizMan]

Nope you will be fine and there is little or no difference between the two.

I would strongly suggest that you use slot 1 and slot 2 :)

Hi fren, I also have that problem before, what I do is I use the 1st DVI as output:

8431

I also install nvidia 296.10 driver, my card placement is like this:

8432

If you install your card like I did, you will have slot 1 and slot 4 in x16, that had been confirm by the test that I did a few days ago.

Can you try and use the 1st DVI as ouput and see if you can enable QUAD SLI, hope it help :)
