Have you connected the SLI bridge? ie, are the 2 cards connected to each other?

Go to NVIDIA control panel and make sure SLI is enabled.

funny it is not there must not have it but how come there is two connections the same beside each other

also my two hdd is connected to sata 3 and 4 on the motherboard and sata 1 amd 2 are free

The SLI bridge looks like:

ASUS P5N-T Deluxe nVidia nForce 780i SLI Motherboard Review - PCSTATS.com

It is NOT connected to your SATA ports on your motherboard.

It is connected to your two video cards:

NVIDIA Quad-SLI with the ASUS EN9800GX2 - HotHardware

Your SLI bridge should come with your motherboard or sometimes it comes withe video card.
