I have a DE3815TYBE and am trying to run a graphics card from it without much look. I'm using a fairly standard mini PCIe -> PCIe x16 riser.
I've confirmed the slot actually works with a wifi card that is recognised just as it should be.
The bizzare thing is the behaviour of the board when a card is plugged in. It doesn't display anything out to my monitor yet the power LED is on. It seems to be in a strange power mode though. The USB Suspend hub LED doesn't come on as it does on a usual boot, and when you press the power button the board briefly powers down before coming back on again, only properly turning off when the button is held for a fairly long time (this is contrary to typical behaviour).
Any thoughts? I know mini PCIe can't handle all 16 lanes, but as far as I can tell using a GPU with a mini PCIe port is fairly common and while limited in bandwidth has none of these issues
Does anyone have any thoughts or maybe avenues to look into?
Thank you for joining the Intel Community Support.
The mini-PCIe connector on the DE3815TYBE NUC board is provided for the addition of a wireless capability. This means that the PCI Express slot will not support external GPUs.
