What TuxClocker is
TuxClocker is a free GNU/Linux program for monitoring and controlling hardware, with a D-Bus daemon and Qt graphical interface. It supports multiple devices at once, and lets users select device properties to read or change. NVIDIA features include fan, clock, and power-limit controls, plus temperature, utilization, and VRAM monitoring; voltage controls and readings are available for 600–900 series GPUs under Xorg. AMD features include fan and clock controls, performance parameters, voltage and VRAM monitoring, and voltage-frequency curve editing on applicable GPUs. CPU functions cover frequency and utilization monitoring, governor settings, frequency limits, power use, and energy-power preferences. Installation options include a prebuilt release tarball and packages for openSUSE Tumbleweed. NVIDIA editing requires Coolbits; AMD editing requires the amdgpu.ppfeaturemask boot parameter. Optional libraries provide vendor support, and python-hwdata can improve AMD device naming. The project uses GPL-3-only licensing and lists GNU/Linux as its current platform focus.
Good
