Re: HOW TO SET UP OVERCLOCKING AND FAN CONTROL ON UBUNTU 16.04 FOR NVIDIA CARDS

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.
