First of all I apologise in advance for my sheer stupidity.
My system:
Proc:- i7 3770k 3.5Ghz @ 4.5Ghz
mobo:- Gigabyte GA-Z77X-UP4TH
Cards:- 2x 680 GTX (KFA2 both exactly the same version) "sli"
I have scoured the interwebs for help with my sli issue. Both cards are detected in device manager as working without any alerts for any issues. Both are being detected on the nvidia control panel however there is no option for sli. Where the sli configurator option should be there is the option "Configure Surround, PhysX".
I have tested each card indiviudally and both are in full working order. I have uninstalled and reinstalled the drivers during this process for each to rule anything out. Also I have tested several different SLI bridges in all configurations.
I have an Asus sound card in the lower slot which I don't believe should affect anything.
The system was built by overclockers UK and as much as I value their skills I can't help but think maybe there is something that was overlooked their end as I have made no changes (as yet) to my system.
On looking at GPU-z I can see the Bus Interface is different for both cards. They are as follows:
Card 1 - PCI-E 3.0x16@x8 1.1
Card 2 - PCI-E 3.0x16@x4 1.1
As far as I can figure out, this is my issue right here however my knowledge is completely lacking in changing these speeds.
Any guidance would be very much appreciated and can it be confirmed that I have diagnosed the issue correctly?
Many thanks in advance for any thoughts over this.
