March 31, 201610 yr Hello, i've been trying to run a VM but I have the problems with NVIDIA Cards and PCI passtrough on primary display/graphics card. I have no integrated graphics and people here pretty much told to buy a cheap pci card. I got one but I can't set it to my primary display in BIOS so i'm trying to set it as primary display when I run unraid console. I can't find a way or a config file to set it manually.
March 31, 201610 yr Hello, i've been trying to run a VM but I have the problems with NVIDIA Cards and PCI passtrough on primary display/graphics card.

I got one but I can't set it to my primary display in BIOS so i'm trying to set it as primary display when I run unraid console. I can't find a way or a config file to set it manually. I am not sure of a way of doing this in unRAID. Are you SURE you can't set which GFX card to use as primary (either by specifying which PCI-e lane to use or simialr)? I have never come across a board that doesn't have this option in some form or another. Not that I dispute what you're saying, I am just surprised. What make / model motherboard do you have?
March 31, 201610 yr Author I am using a P9X79 (non pro) and I have no options to set primary display (maybe there's a custom bios to set it but so far I haven't found neither in the bios istself nor the manual of the card) If someone knows a way it would fix all of my problems. I know the system always boots on PCIEX16_1 (upper slot) and I can't move the cheap card to the top because there isn't enough space between bottom ports for my cards to fit.
March 31, 201610 yr Just a thought, but have you looked at all of the hardware (MB, GPU. etc.) for BIOS (or Firmware) updates?
March 31, 201610 yr Author Yes I have the latest bios update which add support for PCI-E 3.0 but I can only choose GEN 1 GEN 2 GEN 3 in PCI Slot settings
March 31, 201610 yr ...a cheap pci card. Do o mean PCIe or PCI card? AFAIK if you have 2 PCIe cards it will always boot from the one on the 1st slot, if you have a PCIe and a PCI card then it's usually possible to select the one you want in the bios.
March 31, 201610 yr Author I have a 980 Ti, a 970, and a cheap old amd card. I just found out that no matter where I put the amd one the 970/980ti will be prefered if they are plugged.
