Gen2 is one step usually needed,

"Above 4G Decoding"

Have gotten 7 GPUs working with the ASUS Z270-A PRIME.
Here's what I found:
-- Had to flash the BIOS. Board shipped with 5.0.0 and I updated it to the latest (7.0.0 I think)-- this is necessary to get the "Above 4g decoding" option. Which appears on the boot menu in the bios.
-- PCIe switched to Gen2
-- Didn't make the other changes.
WARNING WARNING WARNING
When I flashed the BIOS the onboard network hardware stopped working with linux. this caused a bunch of problems.
I had to run this utility to refresh the network drivers ROM to make things work:
https://downloadcenter.intel.com/download/19186
Current setup for this board-
-- Ubuntu 16.04 server
-- 7x NVIDIA 1070 8GB Cards
Working fine. (And about %10 more hash under linux than under Windows.)

"Above 4G Decoding"

It appears my BIOS does not have that option. It's not in the PCIe (and searching ASUS's site that's where it would be). It's not mentioned in the docs for this BIOS at all.
I see it for some Asus, too:

I should mention, the motherboard is a ASUS Z270A, has seven PCIe slots (so I'm not using one) and the two GPUs that aren't being addressed are on good working risers.
I went into the BIOS and changed all the PCIe connections to Gen2 to increase capacity, but no effect.

Here's the situation:
6 1070 GPUS plugged into an ASUS Z270A motherboard (has 7 PCIe slots, the GPUs are using X1 to X16 Risers).
The OS Can see the GPUS, as you can see below. But some are "unclaimed" and it appears the NVIDIA driver does not "claim" them.
This is a stock Ubuntu 16.04 SERVER install, onto which the CUDA 8.0 driver has been installed.
(Driver is installed by a script that shells into the box to do it, here's the relevant part of the script:)
ssh -n $1 'yes | sudo dpkg -i ~/drivers/cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb'
ssh -n $1 'yes | sudo apt-get update'
ssh -n $1 'yes | sudo apt-get install cuda'
My CUDA app can use the four GPUS it can see just fine. How do I enable the last two?
