'SLI' Not on option in Nvidia control panel w/ 2 GTX 680s

by zrstoddart - 3/5/13 7:20 PM

OK I recently purchased a second GTX 680 instead of dropping the extraneous dough for a 690 or TITAN. Upon installing it, my computer recognizes a second 680 is installed everywhere that matters (EVGA Precision X, Windows Device Manager, CPU-Z, even NVIDIA control panel...) here is a screenshot of all of the listed applications acknowledging my second GTX 680 http://postimage.org/image/arv9q9snx/

BUT, as you see in the picture if you look hard enough at the NVIDIA control panel. No option to enable SLI is present. JUST "Configure Surround, PhysX" with no mention of SLI.

Upon seeing this I started scouring the internet, I flashed my Bios to the latest version, uninstalled my display drivers, re-installed them, uninstalled them again, then installed beta drivers, switched the direction of my SLI connector, switched the PCIE 3.0 slots my cards are in, scoured my Bios for SOME option to enable SLI. NO LUCK. NVIDIA control panel REFUSES to offer the option to enable SLI. I'm losing my mind!!

Here are my specs:
CPU: Intel I7 3770K
Mobo: Asus Sabertooth Z77
RAM: 32GB GSKILL Ripjaws Z 240-Pin DDR3 2400
GPU: 2x EVGA GTX 680
PSU: Cooler Master Silent Pro M 1000W

PLEASE TELL ME HOW TO ENABLE SLI!!
