Okay, does your motherboard support SLI? Does your CPU have enough PCI-E lanes to support SLI? is it possible your SLI Bridge is damaged?

What motherboard are you currently using? What does the translation of the text with the Caution icon next to it say?

My mobo does support SLI as it's written on it. ( its Gigabyte P55A-UD4) and cpu is i5-760...

Gigabyte p55a-ud4 ---> the translation says "for maximum 3d performance connect sli brige"

You CPU supports 1x16 or 2x8 pcie lanes. How many PCI lanes are populated?

If both adapters show in device manager and are the only pieces of hardware in pci slots I would uninstall all nvidia drivers and software. I would remove the sli bridge and reboot. Reload all the drivers from scratch and see if both cards show up in the nvidia control panel. If they do, shutdown and install the sli bridge. When you start back up you should be able to enable sli.

The board definitely supports SLI.

i did clean Windows install w/o sli bridge. installed nVidia drivers in safe mode and then connected them with the bridge.

Try pulling the bridge out slightly. Sometimes it is not recognized when plugged all the way in.

Are you using PCI slots 1 & 2?

[Tiso]

does the bios version matter? one has 70.10.20.00.80 and the other has 70.10.60.00.82 (says on the sticker on pcb of the card)

Wiggle the bridge around abit, they're abit finicky, when I ran my 550ti sli rig I had to have the bridge about half way off the fingers and tilted as far to the right as possible.

- BIOS Version
-- You can use as many different BIOS versions between the cards you have in SLI as you like.

IMO I wouldn't wiggle something in my computer when it is powered on. I would power down and re position. 

[Canio22]

I had to restart to get SLI to be recognised but pulling it half way got that to be detected, but then after enabling SLI I had colour issues with my screens, causing them to have a purple hue, then while the system was on I moved it around until the colours went back to normal.
