Hey guys
I recently bought a new motherboard (MSI 970 Gaming) and a second gpu (same as the first, MSI GTX 760 2gb). After assembling the new components into my PC, it all runs smoothly, except i cant for the love of me get my second GPU to work with my original.
Now, firstly, i know for a fact i put the cards in the right slots and no, i didnt forget to install the SLI bridge!!!
When i flick on the power, i can see both GPU's run (so i know it cant be a PSU problem, ive been told many times 750W is plenty for an SLI configuration.). However only the GPU that is placed in the top PCI slot is detected, when i plug in my HDMI cable into the top GPU, my monitor gets signal. However when i plug it into the bottom gpu, nothing. My device manager and the motherboard BIOS both say only one GPU is installed and that the bottom PCI slot is free & not being used, despite the second graphics card being installed and running.
Next i took both GPU's out and placed each one in the top PCI slot on its own. Both worked completely fine. So i know both graphics cards are ok and actually work.
I did exactly the same with the bottom PCI slot, the cards had power but my monitor wasnt picking up anything for either.
I have uninstalled, cleaned and installed the latest and freshest drivers for my mobo, and gpu's. Still, nothing.
I tried a second SLI bridge, still nothing.
Both Nvidia Control Panel & Windows Device Manager only ever pick up on GPU installed in the top PCI slot and never both.
Ive tried everything i can possibly think of or find solutions for online and im still stumped.
Thank you so much to anyone that has advice. I'm desperate now!
