# NVidia GPU
|
|
|
|
## Ingredients
|
|
|
|
1. [Nvidia drivers](http://www.nvidia.com/Download/driverResults.aspx/104284/en-us) for your GPU
|
|
2. Some form of X11 GUI preconfigured on your linux host (yes, it's a PITA, but it's necessary for overclocking)
|
|
|
|
## Preparation
|
|
|
|
### Install kernel-devel and gcc
|
|
|
|
The nVidia drivers will need the kernel development packages for your OS installed, as well as gcc. Run the following (for CentOS - there will be an Ubuntu equivalent):
|
|
|
|
```yum install kernel-devel-$(uname -r) gcc```
|
|
|
|
### Remove nouveau
|
|
|
|
Your host probably already includes nouveau, free/libre drivers for Nvidia graphics card. These won't cut it for mining, so blacklist them to avoid conflict with the dirty, proprietary Nvidia drivers:
|
|
|
|
```
|
|
echo 'blacklist nouveau' >> /etc/modprobe.d/blacklist.conf
|
|
dracut /boot/initramfs-$(uname -r).img $(uname -r) --force
|
|
systemctl disable gdm
|
|
reboot
|
|
```
|
|
|
|
### Install Nvidia drivers
|
|
|
|
Download and uncompress the [Nvidia drivers](http://www.nvidia.com/Download/driverResults.aspx/104284/en-us), and execute the installation as root, with a command something like this:
|
|
|
|
```bash NVIDIA-Linux-x86_64-352.30.run```
|
|
|
|
Update your X11 config by running:
|
|
|
|
```
|
|
nvidia-xconfig
|
|
```
|
|
|
|
### Enable GUID
|
|
|
|
```
|
|
systemctl enable gdm
|
|
ln -s '/usr/lib/systemd/system/gdm.service' '/etc/systemd/system/display-manager.service'
|
|
reboot
|
|
```
|
|
|
|
## Overclock
|
|
|
|
!!! warning
|
|
Like overclocking itself, this process is still a work in progress. YMMV.
|
|
|
|
Of course, you want to squeeze the optimal performance out of your GPU. This is where the X11 environment is required - to adjust GPU clock/memory settings, you need to use the ```nvidia-settings``` command, which (_stupidly_) requires an X11 display, even if you're just using the command line.
|
|
|
|
This command gives you a "fake" screen so that X11 will run, even on a headless machine managed by SSH only:
|
|
|
|
```
|
|
nvidia-xconfig -a --allow-empty-initial-configuration --cool-bits=28 --use-display-device="DFP-0" --connected-monitor="DFP-0"
|
|
```
