- Check your PSU rating: Make sure your power supply has enough wattage to handle your GPU’s maximum power draw.
- Watch for sudden spikes: Big jumps in power usage can indicate instability, especially when overclocking.
- Combine power and thermal checks: More power usually means more heat, so keep an eye on temperatures at the same time.
- Use results to plan upgrades: If your GPU is drawing too much power for your current setup, you may need a better PSU or improved cooling.
By analyzing your GPU’s power consumption, you can make smarter choices about hardware, efficiency, and system stability, keeping your PC running smoothly and safely.
Overclocking Stability Testing
If you want to get a little more performance out of your graphics card, overclocking is one way to do it.
Overclocking means running your GPU faster than the speed it came with from the factory.
While this can boost your gaming performance, it’s very important to make sure the GPU stays stable and doesn’t overheat or crash.
That’s where overclocking stability testing comes in.
After you increase the GPU’s clock speeds or memory speeds, you need to run some tests to check if it’s still running smoothly under pressure.
You can use stress tests like FurMark or synthetic benchmarks such as 3DMark Time Spy Extreme to check stability.
These tools push your graphics card to work at full capacity, so if something’s wrong, you’ll notice it.
While testing, keep an eye out for these signs of instability:
- Visual artifacts – weird lines, flickers, or blocks on the screen
- System crashes – your PC freezes, restarts, or shows errors
- Overheating – GPU temperatures going too high, usually above 85–90°C
If you see any of these issues, your overclock may be too high. Try lowering the clock speeds a little and test again.
Tips for safe and effective overclocking stability testing:
- Increase speeds slowly: Don’t jump too far ahead—go step by step and test each time.
- Use reliable tools: Tools like FurMark, 3DMark Fire Strike, or Time Spy Extreme are great for checking stability.
- Monitor temperatures: Use software like MSI Afterburner or HWMonitor to keep an eye on heat levels.
