Enabling Advanced View gives access to a wide range of controls along with system monitoring tools. On the top left are multiple performance profiles, including Creator Mode , Game Mode , and two additional options, all of which can be tweaked.
You can also adjust additional parameters, including PPT (Package Power Tracking), EDC (Electrical Design Current), and TDC (Thermal Design Current) with the different PBO modes.
Under Control Mode, you can select Precision Boost Overdrive, which has basic automated EDC, TDC, and PPT values. These values are automatically set to motherboard limits, as the motherboard firmware automatically determines safe values based on its power delivery capabilities.
For more granular control, you can choose Auto Overclocking mode, which allows you to define a Boost Override CPU value that increases the clock speed of the processor beyond the rated boost clock, but this maxes out at +200 MHz. This also unlocks the PBO Scalar option, which increases the amount of time the processor runs at a higher boost clock.
Once you select your desired options, hit Apply and Test at the bottom. The Ryzen Master software will now apply your settings and run a quick test to check for system stability.
Once PBO is active, the CPU should begin using any additional headroom to boost more aggressively during heavy workloads.
With Precision Boost Overdrive enabled, you can now fine-tune the processor using Curve Optimizer. As mentioned earlier, this feature allows you to adjust the voltage-frequency curve of the CPU cores, or in simpler terms, reduce the voltage required for a given clock speed.
Since our goal is to apply a negative curve offset, begin by selecting All Cores to reveal a new section called CO All Core Value. Next, enter a negative value. A good starting point would be –10 before gradually working your way to a lower value, as we don’t want to push the processor beyond its stability limits.
After entering the value, click on Start Optimizing . The Ryzen Master software will run a short validation test to check for stability issues. If the system remains stable, you can save the configuration as a profile.
While Ryzen Master runs a quick validation test, it is best to perform a long stress test to confirm that the undervolt is truly stable, as real-world workloads can behave differently from short synthetic tests. You can test for system stability by running a CPU-demanding game or a benchmark like Cinebench R23 or Prime 95.
Validate your results by running the benchmark before applying a negative voltage offset and comparing the results after applying the offset. Ideally, the benchmark score after undervolting the CPU should improve by a small margin.
Make sure that you also monitor the CPU temperatures, thermal throttling, clock speeds, and system stability during testing. In the event of a system crash, freezing, or hardware error, the curve offset might be too aggressive. Reduce the negative offset slightly and repeat the testing process until you find a stable configuration. With the right settings dialed in, Precision Boost Overdrive and Curve Optimizer can help unlock additional performance and reduce temperatures on your Ryzen processor. By carefully offsetting the voltage, you are allowing the CPU to sustain higher boost clocks for longer during demanding workloads.
Remember, patience is key. Every processor behaves differently, and the ideal settings for one system may not work for another. Take your time to make gradual adjustments and test for stability before settling on a final configuration.
