Hey there everyone!

My PC specs:
Intel i5-3570K with Corsair h100i cooler. [Ive havent done any overclocking's yet]
Kingston Hyper X 1866mhz RAM 16 gigs
Asrock Z77 Extreme6 which has SLI support
Two Inno3D GTX 770
Kingston Hyper X 3K SSD
And two 1TB Western Digital green HDD's
Silverstone Stryder 700W

I did some upgrading to my computer... I bought Asrock Z77 Extreme6 motherboard and two Inno3D GTX 770 which are Hybrid cooled (Water and air).

So the issue is I cant get my cards running in SLI... There is no SLI option in nvidia control panel.

Things ive tried already:

Switch graphics card in their slots, trying to put SLI bridge into left or right on my graphics card's.
Installing drivers that came with the GTX 770 CD and installing the newest ones from nvidia.com
Disabling or enabling IGPU-Multimonitor from BIOS.. I dont know if it even does anything with SLI
Putting PCI-E to work from Auto or Gen3 mode.

Im thinking to install Windows 7 64bit again and installing drivers again.

One thing that I found out too that GPU-Z founds my both graphics card but they seem to have different BIOSES and revision or something... Ill put screenshots below.

And that Bus interface should be 3.0 on both of the cards but one is running at 1.1, and when I run the render test it doesnt go to 3.0 and it stays at 1.1

Hi vikizor,
i have ran into this problem a few times,
Firstly update your nvidia drivers for your 770 then you will have the option for sli in your nvidia control panel , do this from nvidia's site
It is not a problem with windows just your card drivers

Windows 7 installed and it still not working... No SLI options appeared into nvidia control panel.

Ive checked the manual several times and I have my graphics cards in their correct slots.. One in PCI-E2 and one in PCI-E4.

Might it be that my PSU wont be able to give that much power for SLI? I was reading today that 850W PSU should do the trick but I found many posts that said 700W can power it up too..

I am almost positive this is a driver issue , on multiple occasions i have installed cards on a motherboard and gone into the nvidia control panel and found that the option to select sli is not there , i have updated the nvidia drivers and then there is the option to configure sli,surround,physx , i really do believe this is your issue, and yes your power supply has enuff grunt to run these cards.
You have spent a lot of time trying to fix your problem ,
so what can this hurt , please amuse me and download from this link and install
http://www.nvidia.com/download/driverResults.aspx/57492/en-us
after you do this if option still not there check windows update for any graphics related drivers

I like where mickypheonix is going. To add to the driver-suspicion, here's a refinement: Manually uninstall everything related to NVIDIA. You'll have to restart several times in order to do that. After you uninstall the last piece of NVIDIA software, restart your computer again, even if it doesn't ask you to do so. At that point, your system will be more susceptible to the updated driver profiles that you're trying to install. I've had drivers not take when simply installing on top of others. Best of luck :D

Alright thanks for the replys!! :) I hope this is getting me somewhere. Should I do a driversweeper in safemode?? When I installed windows 7 again there was some driver in windows update for Nvidia but I didnt download and installed it.. just went to nvidia.com and downloaded the newest one. But ill try with that mickypheonix linked driver :)

Nope not working! Did that driversweeper in safe mode.. went back to windows to install that mickypheonix linked driver but it doesnt even find my GPU's so I cant install it... Windows update installed some driver and then I went to nvidia.com to download newest one. So no luck this time.. and now I just checked nvidia control panel and there is still no SLI options.

And no I dont have anything else but just two GTX 770 connected to PCI-E slots :)

Actually, thinking about it, when the 780 Poseidon was released, also a Hybrid water and air cooler, someone told me on this forum that those cards cannot be put in SLI Configuration, I don't know why though!

Nope.. I tried straight with two of my cards to install the driver. I might soon try to install the driver with one card in.. And yes I got Geforce Experience.

I have started thinking that too that these hybrid cards cannot be SLI'd.. If I dont get it working anyhow ill just return these cards and take one 780 ti.. :p
