Gtx 970 Sli, "no Sli-Bridge connected"

[DisILLusionZzz]

Hi,

i have an annoying Problem with my two Gtx 970 cards. One is an Inno3D GeForce GTX 970 OC, HerculeZ X2, 4096 MB DDR5 , the second is a 4096MB Palit GeForce GTX 970 JetStream Aktiv PCIe 3.0 x16. I put Ek-Fc 670 Waterblocks and a Backplate on both.

 

These cards run great alone, but i cant start SLI Mode. I run them on an Asus Rampage IV Extreme. The Mainboard LEDs show me, both cards are working. In the Device Manager are 2 Cards, Cpuz and Gpuz shows me 2 cards, Aida 64 Shows me 2 Cards, Msi Afterburner shows me 2 cards. Opening the Nvidia control Panel and clicking on "Sli, Surroung, Physix" i get and Error which tells me to Connect Cards with a SLI-Bridge. I tried 4 different Bridges, i tried change PCIE Slots 1+2, 1+3, 1+4. I changed the upper and the under Card. I tried to put the Board to Pcie 2.0. Not working at all.

Can you help me?

 

Thanks

 

 

P.S.: im sorry for bad english..

Do you have the SLI bridge connected? there are two gold contacts on each card and you should have a ribbon cable to snap onto each one.

is the bridge upside down?

i tried it with 4 Bridges and i connected them right. i tried two different Dual Sli Bridges, one 3sli bridge and another 4sli bridge.

Check your motherboard manual, and look for SLI configurations. Some manufacturers have specific slots for SLI and putting it in any other configuration won't work. I had this problem when I SLI'd my old 760s on an X79-UD3 board from Gigabyte.

I tried it in any possible way. Slot 1 and 3 is the best connection because of x16. The other Ways work too.

 

 

 

 

EDIT: New installing of Windows 8.1 doesnt fix the Problem.

From the sounds of it, I'd say there's a very good chance that they're not SLI compatible.  Check with the manufacturer to be sure.
