Understanding Your Card’s Limitations
Every GPU is different, and some cards will overclock better than others. This is due to manufacturing variations and other factors. It’s important to understand that you may not be able to achieve the same overclock as someone else, even with the same card.
Also, remember that the quality of your GPU cooler matters. A card with a beefy aftermarket cooler will generally overclock better than a card with a stock cooler.
The Overclocking Process: A Step-by-Step Guide
Now that you’ve prepared your system, you’re ready to start overclocking. The following steps will guide you through the process of safely and effectively overclocking your GTX 1660 Super.
Step 1: Establishing a Baseline
Before you start tweaking any settings, it’s important to establish a baseline for your GPU’s performance. This will give you a point of reference to compare your overclocked results against.
Run a benchmark like 3DMark Time Spy or Unigine Heaven and record your score and average FPS. Also, monitor your GPU temperatures during the benchmark to get an idea of how hot your card runs at its stock settings.
Step 2: Incrementally Increasing the Core Clock
The first step in overclocking is to increase the core clock speed of your GPU. Open MSI Afterburner and adjust the “Core Clock (MHz)” slider. Start with a small increment, such as +25 MHz.
Apply the changes and run a benchmark to test the stability of the overclock. Monitor your GPU temperatures closely. If the benchmark runs without any issues, increase the core clock by another 25 MHz and repeat the process.
Continue increasing the core clock until you experience instability, such as crashes, graphical glitches, or driver errors. If you encounter instability, reduce the core clock by a small amount (e.g., 5-10 MHz) until you find a stable setting.
Step 3: Incrementally Increasing the Memory Clock
Once you’ve found a stable core clock, you can start increasing the memory clock. The process is similar to overclocking the core clock.
In MSI Afterburner, adjust the “Memory Clock (MHz)” slider. Start with a small increment, such as +50 MHz. Apply the changes and run a benchmark to test the stability of the overclock. Monitor your GPU temperatures closely.
Continue increasing the memory clock until you experience instability. If you encounter instability, reduce the memory clock by a small amount until you find a stable setting.
Step 4: Adjusting the Voltage (Optional)
Increasing the voltage to your GPU can sometimes help you achieve a higher overclock. However, it also increases the risk of overheating and damage. Therefore, it’s generally recommended to only adjust the voltage if you have a good cooling solution and you’re comfortable with the risks involved.
In MSI Afterburner, enable the “Unlock voltage control” option in the settings. Then, you can adjust the “Core Voltage (mV)” slider. Start with a small increment, such as +10 mV.
Apply the changes and run a benchmark to test the stability of the overclock. Monitor your GPU temperatures very closely. If the benchmark runs without any issues, increase the voltage by another 10 mV and repeat the process.
Be very careful when adjusting the voltage. Do not exceed the maximum recommended voltage for your GPU, as this could cause permanent damage. A good rule of thumb is to stay under +50mV unless you have a very advanced cooling solution.
If you encounter instability, reduce the voltage or the core/memory clock speeds until you find a stable setting.
Step 5: Stress Testing and Finalizing Your Overclock
Once you’ve found a stable core clock, memory clock, and voltage (if applicable), it’s time to stress test your overclock to ensure that it’s stable in all situations.
Run a demanding benchmark like FurMark or 3DMark Time Spy for an extended period of time (e.g., 30 minutes to an hour). Monitor your GPU temperatures closely. If your system remains stable throughout the stress test, your overclock is likely stable.
If you encounter instability during the stress test, reduce the core clock, memory clock, or voltage until you find a stable setting.
Once you’re satisfied with your overclock, you can save it as a profile in MSI Afterburner. This will allow you to easily load your overclocked settings whenever you want to use them. You can also set the profile to apply automatically on system startup.
Fine-Tuning and Advanced Techniques
Once you have a basic overclock, there are a few things you can do to fine-tune it and potentially squeeze out even more performance.
Power Limit Adjustments
Increasing the power limit allows your GPU to draw more power, which can help stabilize higher clock speeds. In MSI Afterburner, you can adjust the “Power Limit (%)” slider. Increasing the power limit can improve overclocking potential, but also increases heat output. Monitor temperatures closely.
Fan Speed Control
Adjusting your fan speed curve can help keep your GPU temperatures under control. In MSI Afterburner, you can create a custom fan speed curve that increases the fan speed as the GPU temperature rises. A more aggressive fan curve can lead to lower temperatures, but also potentially more noise.
BIOS Modding (Advanced)
For experienced users, BIOS modding can unlock even more overclocking potential. This involves modifying the GPU’s BIOS to remove power limits, adjust voltage settings, and more. However, BIOS modding is a risky process that can potentially brick your GPU if done incorrectly. It’s only recommended for advanced users who are comfortable with the risks involved.
