I am having some issues with SLI configuration with 2 Palit GTX 960 OC 2GB.

I've been running a Palit GTX 960 2GB for a couple years now, and since the prices for cards have come back down (thanks bitcoin...), I snagged a second one for $70. I installed the card and utilized the SLI bridge that came with the motherboard. The computer recognizes both cards as being installed, however, there's no option to enable SLI in the Nvidia Cotnrol Panel. I have already looked in the BIOS and don't see any settings regarding SLI. I tested by playing Fortnite and it only showed the primary GPU being utilized. Do anyone know what would cause it to not allow SLI?


System:
MOBO: ASUS P8Z68-V Pro/Gen 3 [BIOS: 3802] (https://www.asus.com/Motherboards/P8Z68V_PROGEN3/)
CPU: i5 3570
RAM: 8GB Crucial (2x 4GB)
GPU: 2x Palit GTX 960 OC 2GB (http://www.palit.com/palit/vgapro.php?id=2442)



Thanks a ton!!

1) Test the new card by itself in the 2nd x16 slot

2) If that works the the SLI bridge is likely defective

3) if #1 fails then move it to the top x16 slot, again by itself (if that passes the card is good if it fails the card is bad)

Basically you need to prove both cards and both slots separately. So if you test the 2nd card in the 2nd x16 slot with the 1st card removed and it works that only leaves the SLI bridge (or damage on one card related to the SLI bridge connection).

Well then I guess the SLI bridge is jacked then, because I had already tried the steps you provided. Tried both cards independently in both x16 slots. As well as swapping each one as the primary and slave. That's weird though, because the bridge was still sealed and never used.
