UXTU4Linux

UXTU4Linux is a power management tool for AMD Ryzen APUs and desktop CPUs on Linux. It lets you set CPU power limits, temperature limits, current limits, clock targets and Curve Optimiser offsets from a terminal, without touching the BIOS.

It runs a background daemon as root. The daemon is the only thing that actually writes to the CPU. The terminal UI runs as your normal user and talks to the daemon over a socket, so you never have to run the whole application as root.

Features

• Four built-in preset levels per CPU family: Eco, Balance, Performance, Extreme
• Custom Preset Editor with around 65 tunable parameters on APUs (34 on desktop CPUs), each with a short description in the editor
• System settings inside presets: power profile, ASUS performance mode / GPU Eco / GPU MUX, CCD affinity
• NVIDIA dGPU clock limit and core/memory offsets
• Automations: switch presets automatically on AC/battery changes and on resume from suspend
• Reapply loop that re-applies the active preset on a configurable timer
• Hardware Information screen with CPU, memory, cache and battery data
• Built-in updater that keeps your config and custom presets across updates
