So i just got a second 670 at a super cheap price. Everything is connected and set up correctly. I turned on my computer and it recognized the second gpu and started downloading the drivers immediately. The problem is i don't actually know how to "activate" SLI. Everything recognizes the second gpu. If turn on msi kombuster is shows me the temp and load for the gpu #2. In Geforce Expirience if i go under my rig it has 2 670's listed. I know i'm suppose to go to the nvidia control panel but i dont have the sli option. Under 3d settings in the nvidia control panel it should have "Configure surround,PhysX, and sli" but i only get that option without it saying sli? Any idea or other ways to set up sli? Is the sli bridge not connected properly?

I already have those drivers installed.

My Nvidia contor panel only has the "Configure Surround phyX" not the "Configure SLI Surround PhysX" tab

I had those drivers installed prior to ever getting a 2nd gpu. Also windows did install drivers for the gpu when i rebooted the cpu with the 2nd gpu for the first time.

Here is Print screen of my nvidia control panel.

Or am i suppose to download and install the 340.52 drivers again and install them in a different folder or what?

Man i feel so bad right now :( i did so much research to make sure my mobo did run sli, but i was looking at the wrong mobo the entire time lol :p. Anywho i guess its time for a upgrade. Any good mobo that suppers sli :) you might recommend for me?
