Objective

Overclock Radeon RX 400 series and newer graphics cards under Linux using the AMDGPU open source drivers.

Distributions

This method will work on any Linux distribution running the AMDGPU drivers.

Requirements

A working Linux install running kernel 4.10 or newer with root privileges and the AMDGPU drivers installed.

Difficulty

Easy

Conventions

  • # - requires given command to be executed with root privileges either directly as a root user or by use of sudo command
  • $ - given command to be executed as a regular non-privileged user

Introduction

The open source AMDGPU drivers don't have a fancy GUI interface that lets you overclock your card. Actually, they don't come with any kind of control center at all. That's alright, though, you can still overclock your card by modifying a couple of values in configuration files, a perfectly Linux solution if you think about it.

Introduction

The following post is a little bit different from my other posts as it does not solve any of your Linux configuration problems. Apologies there! This post is an attempt to kill multiple birds with one stone, hence expose children to a command line, avoid web flash and ads driven multiplication practice tests online and most importantly gain some multiplication skills along the way.

My daughter reached the age where she is required to perform multiplication calculation at school. So together we have developed a below Bash script to take her 1x1 to 10x10 multiplication tables practice to the next level. She approved all the output colours with a "cool" mark, and to my surprise, she was very quickly able to correct my forgotten closing quotation marks during the development thus significantly improving development efficiency:-)

Example

Below is a video sample of running multiplication.sh script with 2 random multiplication, addition, subtraction and division questions:


The script accepts a single argument which is used to set a number of questions asked during the multiplication practice quest. If no argument supplied, it defaults to 20 questions.
