Ryzen 9950X3D Overclocking - BIOS UI Guide
(This is specific to my motherboard.)
PBO Limits
The PBO limits (PPT/TDC/EDC) are measured in mW or mA (as stated in the BIOS). They’re absolute values, so to input 250W, you put in 250000.

Curve Shaper
There are 15 numbers you can set to shape the PBO curve:
| Min Frequency | Low Frequency | Medium Frequency | High Frequency | Max Frequency | |
|---|---|---|---|---|---|
| Low Temp | Low Temp Min Freq | Low Temp Low Freq | Low Temp Medium Freq | Low Temp High Freq | Low Temp Max Freq |
| Medium Temp | Medium Temp Min Freq | Medium Temp Low Freq | Medium Temp Medium Freq | Medium Temp High Freq | Medium Temp Max Freq |
| High Temp | High Temp Min Freq | High Temp Low Freq | High Temp Medium Freq | High Temp High Freq | High Temp Max Freq |
For the purposes of my overclocking, I don’t care about the temperature values. I only care about the frequencies.
For shorthand, I express the curve shaper configuration with 5 numbers:
- The first number is the number set to Min Freq Low Temp, Min Freq Medium Temp, and Min Freq High Temp.
- The second number is the number set to Low Freq Low Temp, Low Freq Medium Temp, and Low Freq High Temp.
- etc.
To achieve this in the BIOS,
