I recently bought a 2nd gtx 1080 strix(one is a tad bit larger but still the same card) When I power on the computer both card light up but only one is synced to what I want it to be. I went into device manager not a single thing is showing up except for the other gtx 1080. I have 2 sli bridges connecting them together right now and both are receiving power. I have reinstalled the drivers multiple times and have also constantly checked for changes to the nvidia control panel to see if it finally recognized the card but it has not. I was wondering if anyone had input as to what the problem may be...
