cannot enable sli
i am having trouble getting sli to show up in my nividia control panel, everything is hooked up properly and both cards show up in the panel yet i do not get the option to turn on SLI.
I have ran the installer every time i installed each card. And after everything was installed i ran it again to do a clean installation yet nothing so far.
I don't know what i have to do more? could it be the sli connector is defective?

Can anyone suggest an idea as to how i can make this work?
I have until Friday to return any part seeing i just bought them and built it during the weekend.


My current set up:

Casing : NZXT PHANTOM
PS : OCZ ZT series 650w Modulable
M/B : AUS P8Z77-V
Intel i7 2600k
GPU 1 : Asus GTX 550 TI Direct CU 1GB DDR5 910mhz Overclocked ( first one on top)
GPU 2 : NIvidia GTX 550 TI 2 GB DDR5

Windows 7 home premium SP 1

Which specific version of the P8Z77-V motherboard do you have? Only some of them support SLI.

Would it happen to be the P8Z77-V LE or LX? Those do not support SLI. Asus likes to make their model numbers confusing.

Hello,

I finally resolved the SLI activation issue on my Asus P8Z77 V-PRO (SLI of 2X 560GTX-TI) :

After long nights spent to figure out a solution I have switched my PSU from a 650W to a 1050W : it worked immediately : did not have to reinstall drivers, the second card was recognized at once and I finally got the posibility to activate the SLI via NVDIA control panel.

I think the power was not strong enough for the 2nd card to "activate"

Note that you will also need to play a bit with the MB BIOS and select the X1 option in the Onboard devices menu, to activate all PCI slots.

I don't have the sli option in my control panel, a common problem indicated by all the posts and sites across the internet I have seen. I bought a new Seasonic 650w psu just for my second 560 ti which I was so stoked to finally being able to sli but I do not think the possible lack of power would cause the control panel to not have the sli enable function so I am going to quit trying to sli. I have spent the entire day trying to fix this and have come to the conclusion I will be going with Radeon when I change cards next. There is also a problem with heat if one doesn't have an ample space between cards. I guess this is why they make 570, 580, and 590 video cards, so one can have great performance without the heat, installation problems, control panel bugs, and overall PAIN of trying to sli. It is so maddening in that I have looked forward to this for months and will have to send back the second 560 ti I just bought. UGH! Nvidia fail.
