Did you mean 17.04 ? Ubuntu site can't have link to 17.10. Only 17.04

PCH option under the PCI-Express speed works on PCI-E X16 slot 0. But I am using PCI-E X1 slot 2,3.
Does it change anything?

Yeah, 17.04LTS.

You need to set all the slots to Gen 1 or Gen 2, whichever one works. Otherwise, you'll get weird Nvidia display errors.

For example: Asus Prime H270 Plus - when it is not set to Gen 1 - on either Gen 2 or Gen 3 you get display errors, before the log in page.

And, only 2 cards are recognised - even though motherboard support is for 4 GPUs on PCI-E 1X.

Hey! Do you have any clues how to make my Asus Z270-P Motherboard recognize 5 or more GPU-s. I can do 4 but not more Sad

i am desperate. Not sure what to do. I use ubuntu 16.04 downloaded from ubuntu site. Desktop version

Have Bios version 0609.

Find DMI/OPI Configuration and change to Gen 1

Find PEG Port Configuration and change to Gen 1

Then after installing drivers on Ubuntu Nvidia drivers go back into bios and find Above 4G Decoding and change it to Enabled

I see you say install the drivers then go back and enable Above 4G encoding. What about if you're using a prebuilt OS with drivers already loaded like pimpOS?

Try it! It takes less than 1 hour to install a Linux OS.

It's just to avoid getting a no display event (black screen) when you don't have drivers installed.

Yep I've been trying everything but can't seem to get past a black screen with 4G enabled on the prebuilt OS I'm using. Was just asking since you mentioned drivers first then enable 4G decoding. Thanks for outlining what you did to get this to work. I've been using xorg.conf to enable overclocking, so interested in giving this a shot and comparing the two methods.

Thanks and have a good one!
