With SLI, do I have to mod in a specific way to make SLI work with the modded BIOS, like should I also mod my VBIOS?

From what I know, I don't think you can buy another gt750M for the y510p lenevo because Lenovo don't sell them individually, unless someone who owns the second graphics and is willing to sell it to you then I doubt there should be an issue installing a second graphic card

I had a similar problem, you have to make sure you have to recent intel proset software and proper drivers, you may need to use previous version of the drivers
