  • Select the Tuning section, where you can enable manual tuning.
  • Adjust the GPU clock frequency by increasing it incrementally, typically in 10-20 MHz steps.
  • Modify the memory clock similarly, watching for stability and temperature.
  • Optionally, increase the power limit slider to allow the GPU to draw more power during peak loads.
  • Monitor GPU temperature and performance metrics in real time to ensure safe operating conditions.

Radeon WattMan also allows you to save custom profiles, which can be switched depending on workload requirements.

Third-Party Overclocking Tools

While Radeon WattMan is the default tool for AMD GPUs, several third-party applications provide more granular control and additional features:

  • MSI Afterburner: Widely used due to its versatility and detailed monitoring capabilities. It supports most AMD GPUs and allows for voltage adjustments, fan curve customization, and on-screen display of performance stats.
  • AMD Overdrive: An older utility still functional for some legacy GPUs, though less commonly used today.
  • GPU-Z: Primarily a monitoring tool but helpful for verifying clock speeds and voltages during overclocking sessions.

When using third-party tools, always cross-reference settings with Radeon WattMan to avoid conflicting commands.

Recommended Overclocking Settings and Limits

Each GPU model behaves differently, so it is crucial to understand safe limits to avoid hardware damage. The following table provides approximate starting points and maximum recommended values for popular AMD GPUs:

GPU Model Base Core Clock (MHz) Starting Overclock (MHz) Max Recommended Core Clock (MHz) Base Memory Clock (MHz) Starting Memory Overclock (MHz) Max Recommended Memory Clock (MHz)
RX 5700 XT 1605 1650 1900 1750 1800 2100
RX 6800 1700 1750 2100 2000 2050 2300
RX 6900 XT 1825 1850 2200 2000 2100 2400

Start with conservative increments and test stability before pushing to higher values. Overclocking beyond recommended limits may result in instability or hardware damage.

Stress Testing and Stability Verification

After adjusting clock speeds and voltages, it is critical to verify stability using stress tests and real-world benchmarks. This process helps identify if the overclock is sustainable or if adjustments are necessary.

Recommended stress testing tools include:

  • Unigine Heaven/Valley: Provides intense graphical workloads to push the GPU.
  • 3DMark: Comprehensive benchmarking suite with stress test modes.
  • FurMark: Known for generating high thermal loads, useful for temperature and stability testing.

During stress testing, monitor key parameters:

  • GPU temperature: Should ideally remain below 85°C under load.
  • Clock speeds: Should stay consistent without throttling.
  • Artifacting or crashes: Visible glitches or system crashes indicate instability.

If instability occurs, reduce the overclock increments or increase voltage cautiously. Always aim for a balance between performance gain and system reliability.

Adjusting Fan Curves and Voltage

Effective thermal management during overclocking often requires tuning your GPU’s fan curve and voltage settings. Increasing fan speeds at lower temperatures helps maintain cooler GPU operation but may increase noise levels.

Key points when adjusting fan curves:

  • Set a gradual increase in fan speed from 40°C upwards.
  • Avoid sudden jumps to maximum fan speed to reduce noise spikes.
  • Use custom fan profiles to balance temperature and acoustics according to your preferences.

Voltage adjustments can improve stability at higher clock speeds but should be approached carefully. Increasing voltage raises power consumption and heat generation, so only increase it incrementally and monitor temperatures closely.
