I'd perform a clean install of the newest Nvidia drivers and start with that. Also you don't need to add a profile for BF3 manually as there is already a profile in the drivers.

If you are running Ultra with MSAA and SSAO at 1080 you won't be getting 110fps with a single card so if that is the case, SLI is likely working but why the usage and clocks are being reported as low is beyond me. Id start with the drivers.

I have latest drivers 304.48. In the picture you can see that the second graphics card is not usage!! I have max 110fps!!

Have you confirmed SLI is working correctly in other applications? Also what settings is the game being rendered at?

The game Sniper elite V2 and call of duty MW3 is ok!!

Lock this pictures. sniper elite 2 work fine

I have the 680s and SLI works fine. Did you install the second card some time after the first? If so, you'll need to install the drivers again. Try the 304.48 beta drivers -- working fine for me.

I have 304.48. I immediately put two With drivers 301.42 the problem is the same
Could you paste the settings in the nvidia control panel for BF3. ( My third image ) ? I do not have Nvidia recommended SLI and this is problem!!

The problem is in the game BF3. In Nvidia control panel no show Nvidia recommended SLI

You may need to reinstall the Control Panel. I use the stock 3D "Global Settings" for all games. Here's settings for BF3 settings:

I reinstall Battlefield 3 and now works amazing. Thanks for all. How much voltage is okay for a gtx 670 on air ?

Here's reply to same question from Jacob over at EVGA:

I think I finally understand how the Power Target slider works, but my questions are:
Is it safe to set it to max (~ +130) given I've the PSU to handle it (Antec TPQ 1200W)?
Is there a max EVGA recommended "safe" voltage? Or should I just trust the card's and Precision X's dynamic voltage handling?
Regards, Rick

Yes 130 is fine, that does not actually increase your voltage, all it does is just increase the power ceiling, so max is fine.


So, don't even touch pre-set voltages, just the Power Target to max (voltage is dynamically handled by the GPU).

Here's settings for 3DMark11:
