Nvidia Control Panel doesn't show SLI options

Hi Everyone,

I have been struggling with getting my SLI to work.

System:
| i7-2770k 3.5gHz | ASUS P8Z68-V Pro | 2x4gb Kingston Hyper X | PoV Nvidia GTX 550 Ti 1gb | Gigabyte Nvidia GTX 550 Ti 1gb | Cougar 750watt PSU | Windows 7 Enterprise |

The VGA cards are:
Connected via SLI link.
Connected to power.
Connected correctly on the Mother Board.

My Mother Board is SLI compatible.
My PSU is SLI compatible.
My drivers are installed and up to date.
I have re-installed my drivers as well.
I have updated my Bios as well. (During which my Primary drive got corrupted and I had to start all over)

Nvidia Control Panel is STILL not giving me any SLI configuration options. It detects that both VGA cards are connected and I can select which core to use, but nothing about SLI.

I'm stuck and need to be pointed in the right direction.

Can anyone offer some advice?

Thanks in advance!:)
