How do i know if both of the cards are in sli correctly? i have 2 650 ti boosts and nvidia control panel is recongizing both cards but nothing is telling me if they are in sli.

Motherboard- GigaByte 970A-DS3P
GPUs- Nvidia 650 ti BOOST 2gb -two of them
 
Solution


Where is the enable sli indicators? I cant seem to find anything in the nvidia control panel referring to sli.
 


3D settings in the top bar, by Desktop. Sorry for the lack of clarity - it should be in the dropdown menu of 3D settings.
 


The only thing that drops down from the 3d settings button is "Show Physx visual indicator"
 


Ok, do you have an SLI bridge between the cards? Just double checking as you need one of them to use SLI
 


Yes i do
 


Some checks to do include:

Is SLI enabled in the BIOS?
Make sure that your video cards are properly seated and that the SLI bridge is installed correctly
Get the latest drivers for you BIOS and video card
Verify that Windows Device Manager is showing two identical graphics cards in the Display Adapters section.
If you have an older motherboard, you may need to configure your jumpers to enable SLI. Consult your motherboard manufacturer's manual for instructions.

Sorry if this is a bit repetitive but it's good just to make sure that all of these conditions are fulfilled to ensure SLI works.
 


I have made sure every one of those is done. At first i was concerned that my motherboard didnt even support sli. it says it supports crossfire but one pci-e port is x16 and the other is pci-e x4

 


It may be that - SLI is different to crossfire I think, the PCI-E port difference may affect it but I am not too sure about that.
 


Alright well thanks a lot for staying here and trying to help :)

 


NP mate, you can always upgrade the motherboard if you really want SLI. :)
 


That right there is why you don't see an SLi option, your motherboard does not support SLi.
