"the Titan X do not want to work with any PCIe slot that isn't a true PCIeX16 power slot." You should try shorting the presence detection contacts, as described in the middle section of my post: http://blog.zorinaq.com/?e=42 http://blog.zorinaq.com/?e=42 That was years ago I did it, but it never failed in making any x16 card work in an x1 PCIe slot.

I'm using these adapters that give me a PCIe x16 mechanical connection as well as the extra juice via a molex/sata power conector: http://www.frozencpu.com/images/products/main/cab-1907.jpg http://www.frozencpu.com/images/products/main/cab-1907.jpg So i don't think I need short the detection contacts to ground i think because the PCIex16 mechanical slot is does it for me (the AMD cards work without any modification). The Titan X doesn't want to work with these, I never paid it much thought since i wasn't going to fill the machine i have with Titan X's anyhow, I just wondered if i can use them when i retire them (i filled with 5970's since i got 4 of those for about 300$ a about a year ago). I will investigate this further if at any point I'll retire the Titan X's and decide to replace my some of the AMD cards, atm I'm still using the Titan's for gaming, and I really don't want to build a mixed GPU rig since it won't give me any boost to performance unless i somehow manually batch my hashes since iirc hashcat doesn't know how to address multi vendor GPU's my itself.

  In my experience many PCIe extenders—even those extending x1 to x16 with a separate power plug—do not short the presence detect pins. Also, I don't think the fact AMD cards work does not mean shorting won't be required for other cards. The PCIe initialization process is complex enough that there could be a variety of reasons why AMD cards can be down-plugged but not your Titan X. In short (pun intended) I would highly recommend you to try shorting if you feel confident in doing it.
