I have one Quadro M4000 and have purchased another new one for much less than the going price to go with it. I need Quadro's for my software otherwise would have gone with one of the top GeForce cards (or 2). NVIDIA says that only certain workstation systems are SLI capable. My build of course is not on their short list. I had been looking at getting a Tesla to pair with the M4000 but talked to NVIDIA support and they said I could not mix the Kepler Tesla with the Maxwell Quadro M4000. He did say that the best bang for my buck would be to buy another M4000. Two M4000 card, not in SLI, have more throughput for may applications than a the M5000, and more CUDA cores.
I see that there has been hack software to run Quadro's in SLI in systems other than the anointed ones. My question is there any harm in trying to get it into SLI? My Extreme 7+ supports it.
Ideas?

I installed the second Quadro M4000 in Slot 4, first one is in Slot 2. Got the 6 pin connectors on 2 separate PCIe cables to the PSU. SLI bridge installed and booted PC. Went to NVIDIA control panel and set SLI from Disable SLI to Maximize 3D performance. The other option is greyed out, 'Activate all displays' Not sure what that means but all are working in SLI after applying and closing. I guess they have opened up a bit on which 'Authorized Systems' can enable SLI on Quadro cards. I did get the latest driver and the notes for it mention added MB support. Now for some testing to make sure it's working nice.

What software are you using? Maya, Max, Cad, and pretty much every single DDC software will not see or use SLI at all. Having 2 Quadros in SLI is pretty useless unless you are really using software and uses raw CUDA.
