No option for SLI in Nvidia Control Panel

[Xythian]

I recently just built my computer and I just put the second graphics card in today. When I went to the Control Panel there is no option to enable SLI(and yes I already completely reinstalled the drivers). I want to say that both of them are detected in the control panel and in device manager. There is just no option for SLI. Any help would be appreciated, thanks!

My system Specs
i7 5960x @ 3GHz (3.5 Turbo)
x1 780 Ti Evga Superclocked w/ACX Cooler
1x 780 Ti Evga Kingston Classified
16gb G.SKILL. Ripjaws @ 3200 Mhz
Corsair 1200w AXI Powersupply
Motherboard ASUS x99 Rampage Extreme V

Kingston or Kingpin?
Do they both have the same amount of memory? It used to be SLI required both cards have the same amount of memory. That may have changed, however.

Also, is the SLI bridge installed?

I figured it out, thanks for the help and the GPUs are Kingpin(Typo on my part). Had to change the GPU's slot it was in.
