Ryzen 7000/9000 Undervolting Guide

DIFFICULTY: BEGINNER UPDATED: JANUARY 2026

>> INTRODUCTION

🇩🇪 Deutsche Version
Ryzen Undervolting Hero

RYZEN UNDERVOLTING

More performance, less heat – for free.

⚡ WHY DO THIS?

AMD Ryzen 7000 and 9000 processors come with very aggressive factory settings. With Curve Optimizer (Undervolting), we can lower the voltage.

The result:

  • Cooler Temperatures (-5°C to -15°C)
  • Higher Clock Speeds (Sustained boost)
  • Lower Power Consumption

⚠️ WARNING:

While undervolting is very safe compared to overclocking, extreme instability can lead to data loss. Test your system thoroughly! All changes are done at your own risk.

>> TOOLBOX

You will need these free tools:

HWInfo64

For monitoring temperatures and clock speeds.

Cinebench R23/2024

Benchmark to test performance.

OCCT

Stress test for system stability.

>> THE PROCESS

1

ENTER BIOS

Restart your PC and press DEL or F2 to enter BIOS. (Press F7 for "Advanced Mode" if needed).

2

FIND PRECISION BOOST OVERDRIVE (PBO)

Navigate to:
> Advanced CPU Settings or > AMD Overclocking

Look for Precision Boost Overdrive.
Set it from "Auto" to Advanced.

BIOS PBO Menu
3

CONFIGURE CURVE OPTIMIZER

Open the Curve Optimizer submenu.

Setting Value
Curve Optimizer Mode All Cores
Sign Negative (-)
Magnitude 15
Curve Optimizer Logic

What do these values mean?
Negative: We are removing voltage.
Magnitude 15: We start with -15 counts (approx. -45 to -75mV). This is a safe starting point for almost all Ryzen 7000/9000 CPUs.

* Pros use "Per Core", but "All Cores" is sufficient for 95% of results.

4

TEST & OPTIMIZE

  1. Save and exit BIOS (F10).
  2. Windows boots? Good. Run Cinebench.
  3. Compare your score with before. You should have a higher score!
  4. Run OCCT for 30min (CPU Test).

System crashes?

Go back to BIOS and change Magnitude from 15 to 10 or 5.

Everything stable?

Try Magnitude 20, then 25, until it becomes unstable.

>> CONCLUSION

You have successfully undervolted your CPU! Expect lower temperatures with equal or better gaming performance. This is one of the easiest and most effective tweaks for modern Ryzen systems.
