CRITICAL: Safety First

FurMark is a "GPU Burner" designed to pull maximum power. Do not run FurMark if you have:

  • An inadequate or low-quality power supply (PSU).
  • Poor case airflow or non-functional GPU fans.
  • An extremely high manual overclock without testing smaller increments first.

How to Run a Proper Stress Test

1

Preparation

Close all other intensive applications and monitoring tools that might conflict. Ensure your GPU drivers are up to date. Open a hardware monitor like GPU-Z to track secondary sensors.

2

Configure Settings

Start with a standard preset (e.g., 1080p). Enable "Artifact Scanner" to automatically detect stability issues. If testing an overclock, start with "Windowed" mode to easily exit if the system hangs.

3

Monitor and Observe

Run the test for 15-30 minutes for a quick stability check, or 2 hours for a thorough "burn-in" verification. Watch the temperature curve—it should level off and stay within safe limits (usually below 85-90°C).

Troubleshooting Common Problems

Thermal Throttling

If you see your clock speeds dropping or the frame rate becoming inconsistent, your GPU is likely thermal throttling.

Solution: Check your GPU fans, clean out dust from the heatsink, or consider undervolting/re-pasting the GPU if it's an older model.

System Shutdown/Crash

A total system shutdown during FurMark usually indicates a Power Supply Unit (PSU) failure. The extreme power draw of the "GPU Burner" can trigger OCP (Over Current Protection).

Solution: Test with a higher-wattage PSU or reduce the power limit in your GPU tuning software to see if the crashes stop.
