- Balance stability and thermals
- Stability testing:
- Run extended stress tests
- Play demanding games for several hours, including 4K and 8K gaming
Remember, patience is key when finding your card’s stable limit.
Advanced RTX 4090 Overclocking Techniques
For those seeking extreme methods:
- Custom fan curve:
- Create an aggressive curve that ramps up after 60°C
- Aim for 100% fan speed by 75°C
- Undervolting:
- Use the voltage/frequency curve editor
- Find the highest stable frequency at each voltage point
- BIOS flashing (advanced users only):
- Research custom BIOS options for your model
- Always backup your original BIOS
- Water cooling:
- Consider a custom loop for maximum cooling potential
- Potential to hit 2.8 GHz or beyond on core clock
Warning: These techniques come with increased risks. Proceed with caution and always prioritize stability over raw performance.
Real-World Performance Gains from RTX 4090 Overclocking
Let’s compare overclocked vs stock performance:
| Benchmark/Game | Stock Performance | Overclocked Performance | Improvement |
|---|---|---|---|
| 3DMark Time Spy Extreme | 13,500 | 14,500 | +7.4% |
| Unigine Superposition (8K) | 14,000 | 15,400 | +10% |
| Cyberpunk 2077 (4K, RT On) | 62 FPS | 68 FPS | +9.7% |
| Microsoft Flight Simulator (4K) | 75 FPS | 82 FPS | +9.3% |
| Red Dead Redemption 2 (4K) | 110 FPS | 121 FPS | +10% |
Note: These are average results. Your mileage may vary depending on your specific card and cooling solution.
Ray tracing and DLSS performance also see significant boosts:
- RT performance: 7-12% gains in RT-heavy scenes
- DLSS performance: Up to 15% improvement in DLSS Quality mode
Power consumption does increase with overclocking:
- Stock configuration: ~450W peak
- Overclocked configuration: ~500-550W peak
For efficiency, undervolting can maintain stock performance while reducing power draw to ~400W, or push performance +5% while staying at ~450W.

Troubleshooting Common RTX 4090 Overclocking Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Immediate crashes | Overclock too aggressive | Reduce core clock by 25MHz steps |
| Crashes after extended use | Thermal buildup | Lower clocks or improve cooling |
| Artifacting | Memory overclock is too high | Reduce memory clock by 50MHz steps |
| Sudden performance drops | Thermal throttling | Check temps, adjust custom fan curve |
| Black screens | Driver conflicts | Clean install drivers with DDU |
Remember the “overclocking shuffle” when fine-tuning:
- Reduce core clock slightly (-25MHz)
- Increase memory clock (+100MHz)
- Raise power limit (+5%)
- Test and repeat
