**This guide is specifically designed for, and tested on ubuntu server 18.04, and for NVIDIA GPUs**



# Start with your rig running WITHOUT the GPUs connected



# Install Ubuntu Server 18.04



Don't update the installer when asked, just follow normal installation



# Fix pciebus error severity corrected



[pcie-bus-error-severity-corrected](https://itsfoss.com/pcie-bus-error-severity-corrected/)



```bash

sudo nano /etc/default/grub



GRUB_CMDLINE_LINUX_DEFAULT="pci=noaer"



sudo update-grub



sudo shutdown -h now

```



# Now connect the GPUs to risers and motherboard



then start the rig again.



# Set Static IP



[Set static ip address](https://linuxize.com/post/how-to-configure-static-ip-address-on-ubuntu-18-04/)



First list your network interfaces:



```bash

ip link

```



And a tipical output could be:



```bash

1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: ens3:  mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000

```



Where ```ens3``` will be the interface name



So create the config for static ip:



```bash

sudo nano /etc/netplan/01-netcfg.yaml

```

Use spaces, no tabs, the interpreter is very strict, and obviously choose your address and gateway accordingly to your home intranet, as the name of the interface.



```

network:

  version: 2

  renderer: networkd

  ethernets:

    ens3:

      dhcp4: no

      addresses:

        - 192.168.121.199/24

      gateway4: 192.168.121.1

      nameservers:

          addresses: [8.8.8.8, 1.1.1.1]

```

Apply it and reboot:



```bash

sudo netplan apply



sudo reboot

```



# SSH from now on!!!



Now your rig will always have the same IP



# update system



```bash

sudo apt update && sudo apt dist-upgrade -y

```



# install needed packages



```bash

sudo apt install dkms libmicrohttpd-dev libssl-dev libudev-dev libncurses5-dev libncursesw5-dev cmake build-essential libhwloc-dev git curl nano p7zip unrar unzip xinit inxi xterm

```



# install nvidia cuda and drivers



```bash

sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/3bf863cc.pub

sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub



curl -O "https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-repo-ubuntu1804_10.0.130-1_amd64.deb"



sudo apt update

sudo apt dist-upgrade

sudo apt install cuda

```



Then reboot:



```bash

sudo reboot

```



Now install the cuda toolkit:



```bash

sudo apt install nvidia-cuda-toolkit

```



and check to see what the hugepages is set at for your current user:



```bash

/sbin/sysctl vm.nr_hugepages ; ulimit -l

```



If the result is vm.nr_hugepages = 0 then hugepages is not on.  We will now enable hugepages:



```bash

sudo nano /etc/sysctl.d/60-hugepages.conf

```



Then add the following



```bash

vm.nr_hugepages=128

```



Now edit memlock size:



```bash

sudo nano /etc/security/limits.d/60-memlock.conf

```



The add the following:



```bash

* - memlock 262144

root - memlock 262144

```



reboot again



```bash

sudo reboot

```



# Check nvidia hardware



Check nvidia-smi



```bash

nvidia-smi



nvidia-smi -L



nvidia-smi --query-gpu=index,name,gpu_bus_id,pci.device_id,pci.sub_device_id --format=csv

```



List pcie VGA devices:



```bash

lspci -vnn | grep VGA -A 12

```



# Create and edit xorg.conf for overclocking



```bash

sudo nvidia-xconfig --cool-bits=31 --allow-empty-initial-configuration

```



Do not consider the ```No package 'xorg-server' found```, the xorg config file is now available.



Now, before editing xorg config, copy the ```edid.bin``` file included in this repo in your home folder



```bash

cp edid.bin /home/YOUR_USERNAME/edid.bin

```



Now edit ```xorg.conf```



```bash

sudo nano /etx/X11/xorg.conf

```



Then use the ```xorg.conf``` included in this repo as a template, just modify it to fit the number of GPUs installed in your rig.



Here an exemple of an hypotetical rig with 6 GPUs installed:



```bash

# nvidia-xconfig: X configuration file generated by nvidia-xconfig

# Edit visudo



We need to add NOPASSWD permissions to some commands in order to have overclock working, edit visudo:



```bash

sudo visudo

```



then add this at the end of file:



```bash

# nvidia overclock

user    ALL = (ALL) NOPASSWD: /usr/bin/xinit

user    ALL = (ALL) NOPASSWD: /usr/bin/nvidia-persistenced

user    ALL = (ALL) NOPASSWD: /usr/bin/nvidia-smi

```



save and exit, then reboot



```bash

sudo reboot

```



# Test it and start mining



Everything is configured now, just use the included resetGPUs.sh script to test the system ( the script just remove any overclock and stops all fans ) and if no error appears, then you're ready to mine, just download the last release of the miners of your choice and configure them!



Included in this repo there is a generic template script for that, just use it as a guide to configure and overclock properly your gpus.



# Enjoy! and Donate



This mini guide seems an easy one, but it really took a lot of time to clean it up and redude it to the minimum, it's not a wide documented topic, there are a lot of tutorials over there, but most of them always lack some information or are outdated.



If you want to mine DIY, without pre-builded mining OS, this guide will be really helpful, but if you want to have it easier and don't mind paying a little for that, HiveOS ( free for the first worker, and for other three if mining on their Hiveon pool ) or Simple Mining ( first month free, then 2$ per worker per month ) are really good options.
