MSI Afterburner is the gold standard on Windows. But on Linux, we need a different approach.
Welcome back to MusaBase. If you have an AMD Radeon GPU and want to overclock, undervolt, or set custom fan curves on Linux, you have probably searched for an MSI Afterburner alternative. Good news. It exists. But not as a single tool.
The first time I tried to overclock my AMD GPU on Linux, I felt lost. I opened the terminal, found nothing obvious. Then I discovered CoreCtrl. A few clicks later, I was adjusting fan curves and pushing memory clocks. But CoreCtrl alone is not a complete MSI Afterburner replacement. It works only with AMD GPUs and handles hardware tuning, not in game monitoring. For that, I found MangoHud. It gives us exactly what Afterburner's on screen display does: FPS, temperatures, clock speeds, and usage while we play.
In this guide, we will learn:
- Installing and configuring CoreCtrl for AMD GPU overclocking, undervolting, and fan curves
- Setting up MangoHud for real time in game monitoring
- Creating performance profiles that auto switch per application
This guide is for AMD GPU users who want full control on Linux. Just CoreCtrl for tuning and MangoHud for monitoring.
