Can't enable SLI mode with new 2nd 770

[discoslice]

I just got a 2nd PNY 770 OC 4 gig - finally got the correct power cable so both cards are detected and working fine. I got an Asus SLI bridge connecting them as well.

But, in nVidia control panel there's no SLI option

I did some Googling about this but couldn't come up with a solution. Help!

What motherboard do you have?

Gigabyte GA-Z68A-D3H-B3 Intel Z68 Chipset DDR3 ATX MB w/ Lucid Virtu + Intel Smart Response Technology & 7.1 Dolby Home Theater Audio. I tried fiddling with some things in BIOS but it didnt seem to help so far. I'll try re-seating the cards but I doubt that will do it.

You have three PCI-Ex16 slots. Check to make sure the second card is in the slot that runs at x8 as you cannot SLI with the slot running at x4.

Ya I have them both in PCI-Ex16 slots. I just swapped their places - no luck. I guess it could be the bridge, but I just bought it. There's another PCIE-16 slot I could try since I have three.

I have the SLI bridge on the finger closest to the base - I have 2 fingers on each card. I tried both fingers with no luck.

Guessing you did not understand my previous post. You have three PCI-Ex16 slots

PCI-Ex16 (@x16) - You must have a graphics card installed here for SLI.
PCI-Ex16 (@x8) - You must have a graphics card installed here for SLI.
PCI-Ex16 (@x4) - You cannot have a graphics card installed here for SLI.

You need to refer to your motherboard manual to determine which two PCI-Ex16 graphic card slots you need to be using for an SLI configuration.

I moved one of the cards to the other PCI-e slot and SLI works now thanks!
