TuxClocker review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

TuxClocker is an open-source GPU overclocking and hardware-monitoring application for GNU/Linux. It is designed for Linux users who want graphical control over supported NVIDIA and AMD GPUs rather than relying only on command-line tools. The Qt interface presents device properties, while a D-Bus daemon provides a separate architecture for reading and changing supported settings. Multi-device support makes it relevant for systems with more than one compatible GPU.

Its main strength is the breadth of controls available in one application. TuxClocker can read and edit GPU clocks, set and read voltage, edit voltage curves on supported GPUs, control fan speed and fan modes, and adjust power limits where the hardware allows it. Temperature, utilization, and VRAM monitoring add operational visibility. Tuning profiles can be applied at startup or when a profile changes, and connections between readable and writable properties can support automation such as fan curves. This gives the product a wider scope than a tool focused only on clock adjustments.

Hardware and driver compatibility define the practical limits. Feature availability depends on the GPU model, driver, and configuration, so the full set of controls is not universal. NVIDIA voltage control is documented for 600–900 series GPUs and Xorg, while several AMD controls are model-specific. Users who need predictable support across different operating systems, hardware generations, or configurations should consider a more narrowly targeted alternative. TuxClocker fits Linux users who are comfortable matching its controls to their GPU and driver environment; it is less suitable when broad, uniform compatibility is the priority.

TuxClocker pros and cons

• Where it wins
  • Controls clocks, voltage, fans, power limits, and monitoring
  • Supports multiple devices with profiles and startup application
  • Combines a Qt interface with a D-Bus daemon for automation
• Where it doesn't
  • GPU features vary by model, driver, and configuration
  • Some voltage controls are limited to supported hardware
  • Linux is the only supported operating system
