SLI Option Not Appearing

Good evening!

I have recently joined Tom's Hardware, and this is my third time posting the same thread for the third time, hoping I might receive more than just one response, and even a solution to my problem.

I have been having difficulty setting up SLI on my system. The two graphics cards I am using are the EVGA GTX 670 4GB. One however, is the FTW edition, which I was informed should not be an issue for SLI as long as the RAM is consistent.

The SLI option is available when my SLI bridge is disconnected on my NVidia control panel, I even receive a notification on my taskbar indicating that SLI can be configured.
Once entering the NVidia control panel to configure SLI, I of course am given a message that I need to connect the SLI bridge to enable SLI. After connecting the SLI bridge, the SLI configuration option in the NVidia control panel is gone.

I have replaced the SLI bridge thinking that was the issue, I assure you it is not.

System Specs:

Processor: Intel Core i7-3770k
Motherboard: ASUS Sabertooth Z77
Graphic Card(s): EVGA GTX 670 (2)
Hard Drive: 1T

Thanks for the feedback!

  1. Are you connecting the bridge with the system powered up?
  2. Thank you for the prompt reply!

    I am not connecting the bridge while it is powered on. This is done while the system is off.
  3. that's good, your post gave me the wrong impression. What PSU are you using?
  4. I am using a 850W PSU manufactured by CoolerMaster.
  5. That should be more than enough, what driver version?
  6. The driver version on my graphic card is 327.xx
