Can we make SLI bridge between our graphics cards for a faster rendering on blender Cycles renderer? I saw on the blender version 2.79.4 we can faster render on 64*64 render tile on CPU and GPUs, together... that is better than just using GPUs... But I believe it would be even faster when we could render in SLI mode...

2$\begingroup$ Blender works more efficiently when working with each GPU separateley. As far as I know SLI doesn't help you render faster. Splitting the load between CPUs does. But make a test and report back... $\endgroup$– user1853Commented May 8, 2018 at 16:46

SLI was designed to be used in accelerating rendering to display in supported applications with OpenGL or Direct 3D, by either alternating the frames or splitting the frames between the GPUs. As Blender uses the CUDA engine when rendering, and has built-in support for using several cards simultaneously, there is no benefit from enabling SLI.
