I just built a system with a x8dah+ mobo that was refurbished and has two xeons on it. I installed a gtx 1060 from evga bstock on it and am using a 750w psu to power the system. The issue when I turn on my machine, everything seems fine, but when I try to hook it up to the monitor, the monitor picks up nothing from the graphics card (connected through hdmi). The graphics card glows white when the machine is on, but only one fan spins. I tried moving the graphics card to a different pci-e slot and using different hdmi cables, but the issue persists. I have does not have onboard graphics either, so I kind of need the graphics card to work. Also the motherboard. Is the issue that the motherboard only has pci-e 2.0, or is the issue not with compatibility, but with the hardware?

  • GTX1060 requires PCIe 3.0. – GabrielaGarcia Oct 28 '18 at 22:48

    @GabrielaGarcia no it does not. You can use it on a 2.0 slot. – DrZoo Oct 28 '18 at 23:45
  • @DrZoo The Nvidia specs say PCIe 3.0. That and only one fan spins pretty much explains why GPU video output is not working. And why would Nvidia not explicitly say it's backwards compatible with 2.0 if it is? – GabrielaGarcia Oct 28 '18 at 23:46
  • @GabrielaGarcia What about the Nvidia page? PCIe 3.0 is backwards compatible with PCIe 2.0. It does not require a PCIe 3.0 slot. – DrZoo Oct 28 '18 at 23:52
  • @DrZoo The backwards compatibility as I understand it is like PCI3 2.0 devices can work in a PCIe 3.0, not necessarily the other way around. Do you have experience with or a reliable source confirming your assertion? And what about the OP's problem, any idea? – GabrielaGarcia Oct 28 '18 at 23:57
