GTX 690 internal sli NOT recognized

[j6044]

Hoping you guys can help me out.

It seems that my pc will not recongize the internal SLI of the 690.

When all 3 dvi ports have a display attached only 2 and 3 will output.

When only 1 display is attached to dvi 1 port it operates fine.

Device manager and precisionx only sees 1 GTX 690 (regardless of which ports actually have signal).


Opening up nvidia control panel and going to 3d settings / configure surround, physx has the "span displays" greyed out.

EVGA has sent me another board and the symptoms are exactly the same.

Evga wants me to reinstall the OS...

I have switched pci e ports and it made no difference.

Any ideas would be appreciated.

My next move is to send them both back and get a refund.
