I've been running an EVGA GeForce GTX 780 Ti Superclocked GPU and I just installed a 2nd card to run SLI (same exact card but the new one has an EVGA ACX cooler on it). I put it in the 2nd slot, which is where it says to put it on my Asus Maximus VI Formula MB. When I first powered on my system, it installed an Nvidia driver, but my PC doesn't recognize my card. According to Nvidia, to enable SLI, you must select SLI in the Nvidia control panel, but an SLI option isn't where it says it is. Actually, nowhere in the Nvidia control panel is an option for SLI.
Is there a different driver I need to use or does something need to be changed in my BIOS? When I go into my BIOS, under PCIe configuration, it shows my original card in slot 1, now running at 8x instead of 16x (when running SLI on this MB, it says slot 1 and slot 2 will run at 8x, instead of 16x, which it does when running 1 card).
So this makes me think the MB recognizes the 2nd card, but something isn't configured right. I have both slots set for GEN3, and if I boot without the SLI bridge installed, it still doesn't recognize the card.
Here are the specific details for each card. One card, the new one, has a slightly higher base clock than my older card, but I didn't think that would make much of a difference since I have my older card OC'd.
These are both EVGA cards.
New card: Part Number: 03G-P4-2884-KR
Old card: Part Number: 03G-P4-2883-KR
Does anyone have any suggestions to get these working, or at least getting the 2nd card recognized? And just so you know, I'm running a Corsair AX1200i PSU so I should have enough power. I have my original card watercooled, and I plan on watercooling the 2nd card, but I just want to make sure it's working first. The 2nd card is also a tight fit because the tubing from my 1st card runs to my Z87 chips waterblock next, which is right between the 2 cards. I thought about unhook in my first card and just running the new card by itself to make sure it's working properly, but I'd like to exhaust all my other options first since it's going to be a pain in the ass to remove the card from my waterloop so I can run the other card by itself. Would it make any difference if I uninstalled all my drivers running my 1st card, installing both cards, and then reinstalling the drivers when I have both setup? Or would uninstalling Precision X, which is what I use to OC my card, and try to set them up running at their base clocks or up the levels on the old card to match the base clock of the new card since the new card has a slightly higher base clock?
I know this is a long post, but I wanted everyone know exactly what I have and what I've done to reduced the back and forth initial questions. Please, I hope someone could provide some suggestions. Thanks!
