When PBO limits are turned off, the system uses the default stock configurations, meaning PPT 142, TDC 95, EDC 140 work as intended—no issues there. To lower power usage, you must switch to manual mode and adjust the values yourself. The choice isn't about right or wrong; it hinges on your specific objectives with undervolt settings. If you're only applying the undervolt adjustment, disabling PBO limits is a smart move so the CPU stays within its standard power draw—Auto typically handles this automatically, which can lead to higher consumption, hence the video recommends setting it to "Disabled."
I'm not very experienced with this, so it's best to disable it completely. Disabling means keeping the CPU below 1.5V at all times. I tested another game and noticed the CPU consistently ran at 4.8GHz with only 1.4V, playing for many hours at that level. Since my CPU is already stable in that range, I think it's safe to keep it there. Overall, I'm satisfied with the lower temperatures and higher clock speeds as shown in the video.
To maintain its stock performance, keep the CPU disabled. Adjusting the power settings requires manual changes. The 1.4V specification aligns with AMD's design goals, and long-term testing by der8auer shows the Ryzen 5000 series can operate stably at a consistent 1.45V for extended periods with little to no decline, making it suitable beyond typical gaming use.
You're looking for improvements in overall core performance, reduced power consumption, and stable temperatures. Voltage settings are just one factor, and using PBO2/CO won't cause damage to your CPU or board.
@YoungBlade captures the essence perfectly. These adjustments are typical, especially with Curve Optimiser in place, which often raises performance to 4.7 in games and around 4.3–4.4 across all cores in Cinebench. That’s solid efficiency at lower temperatures. On my end, I achieve -30 on every core, PPT at 175, TDC at 110, and EDC at 155, giving a 4.5Ghz all-core Cinebench score and 4.7–4.8 in games under 75°C air cooling. You can use these as a starting point and adjust if needed. It looks like you have a strong chip, so the settings should work well.
Comparing Intel and Ryzen is like mixing apples with oranges—it doesn't make sense.
You're doing a solid 100% load for about an hour of gaming. The voltage and temperatures look normal overall—core voltage stays around 1V, CPU core voltage fluctuates but stays in the expected range, and core temperatures average around 60°C. During intense gaming, spikes up to about 70°C are typical, which is within safe limits for most systems. Your cooler appears to be handling the load well despite being a small 240mm AIO model. Keep monitoring temps if you notice any unusual behavior.
Are you working with voltage shifts? If yes, then stay away. I'm wondering since your voltage isn't falling as expected.
