Now all works fine including overclocking and powerlimits, just one trouble left - if I connect 8-th GPU, nvOS hangs on boot
Allright, i've done with the hanging-on-boot problem on z270-p rig with eight gp106-100 onboard. When I discovered this issue for the first time I have tried to update BIOS right away, done it, and the problem persists. My mistake was that I've tried to update BIOS online from Asus server. Later I've discovered that online update's latest BIOS version is not the same as the latest BIOS version on their website. Only when 0810 version of BIOS was installed, my rig started to boot normaly with 8 GPUs connected.
So I suppose we should add this info about Asus z270-p to FAQ - nvOS works normally with 8 GPU on this motherboard only from BIOS ver.0810.
Also important current info about GP106-100 - in my case full headless rig with monitor never connected requires Xorg reconfigure to start mining:
Code:
sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration
sudo reboot
sudo reboot
