How to get NVIDIA GTX 660 SLI working?

I've asked this question on multiple forums and IRC channels. When I use Option "SLI" "Yes" my computer freezes with a black screen when I startx. There is nothing in the xorg logs. SLI works fine on Windows. I've tried installing nvidia-beta drivers but it still freezes with a black screen. I've had this issue over a year now and have always been told to just wait for nvidia to update their drivers but I don't think waiting is getting me anywhere.

The output of "lspci | grep VGA" is:

01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1)
04:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1)

My complete xorg.conf file:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 352.21  (buildmeister@swio-display-x64-rhel04-13)  Tue Jun  9 22:44:03 PDT 2015

Have you tried the alternative arguments for SLI, as described in the wiki?
