IMPORTANT: Safety Guidelines

FurMark operates as a "GPU Burner" that draws maximum power. Avoid running FurMark if your system has:

  • An insufficient or low-quality power supply unit.
  • Inadequate case ventilation or non-working GPU cooling fans.
  • An aggressive manual overclock that hasn't been validated through incremental testing.

Guide: Running a Proper Stress Test

1

Step 1: Preparation

Shut down all other resource-intensive applications and monitoring tools that could create conflicts. Verify your GPU drivers are current. Launch a hardware monitoring tool such as GPU-Z to track additional sensor data.

Step 2: Configure Test Settings

Begin with a standard preset such as 1080p. Activate the Visual Error Detection for automatic stability issue detection. If testing an overclock, use Windowed mode for easy exit if the system freezes.

Step 3: Monitor & Observe

Execute the test for 15-30 minutes for a quick stability check, or up to 2 hours for thorough burn-in validation. Monitor the temperature curve closely — it should plateau and remain within safe thresholds, typically below 85-90°C.

Solving Common Issues

Problem: Thermal Throttling

If you notice clock speeds decreasing or frame rates becoming erratic, your GPU is most likely thermal throttling.

Solution: Inspect GPU fans for proper operation, clean dust from heatsinks and filters, or consider undervolting or re-pasting thermal compound on older GPUs.

Problem: System Shutdown or Crash

A complete system shutdown during FurMark typically points to Power Supply Unit inadequacy. The extreme power draw from the GPU Burner can activate OCP (Over Current Protection) circuits.

Solution: Try testing with a higher-wattage PSU, or reduce the power limit in your GPU tuning utility to determine if crashes cease.
