Don't have SLI option in nvidia panel

[Sunne boy]

So i reformat my pc and tried to SLI both of my cards.
but i don't see the SLI options there


My specs:CPU: i7-4770k
GPU: 2x Gigabyte GTX760 Windforce 3 fan OC 2gb
Ram: 8GB corsair platinum dominator
Mobo:z87-gd65
PSU:GS700

Tried 2 different bridge
Tried reinstalling the drivers
Tried reinstalling the Windows
Tried to update my windows
Tried both card on my main PCIe slot
GPU z detects both of my card But one of the card's bus interface is PCI-E 3.0x16@x8 3.0

and the other one is PCI-E 3.0x16@x8 1.1

a does your board support 2-x16 slots?? or 1x16 and 2 8x by 8x? also if you hit that ? and start the render test watch and see if the buss interface changes it shouls or may jump higher from idel when the card are in full use

also how did you uninstall and reinstall the driver?
