I've put together a bit of a beast for doing Photogrammetry (3D scene reconstruction with photographs). As this software is CUDA and CPU heavy, I want to continue to use my old GTX660 with the new dual GTX1080s. But when all three are installed, the GTX660 rarely shows up (maybe 1 in 20 boots).
Power connections are fine, I've reseated the GPUs, I've tried isolating PCIe slots (love the DIP switch feature), I've tried changing slots around, I've tried it with and w/o SLI on the 1080s. Nothing seems to get the GTX660 to show consistently.
One curiosity, is that in the BIOS it sees the GTX660, but doesn't provide any details (except that it's running at x8 speed). I don't know if that's because it's an older card, or if it's indicative of a real problem.
At any rate, I've moved the card to my old box, and it works fine. So the card doesn't seem to be the issue.
Any thoughts as to how to further diagnose the problem? Is this a known thing with Asus GTX cards? It's really hard to search for this particular problem, as I typically am finding SLI threads. 🙂

I think you put your 660 in the PCIEX8_4, because it shares bandwidth with Plextor M8Pe M.2 2280 1TB NVMe, that is why you losing 660.
Please use PCiEX16_3 for the third PCI card. Do not do SLI on third card also. Just SLI for the 2 1080. Also, another thing, take out the 660 card and put it back in and make sure it is installed correctly. You will get have stable 660 card.
