Fix Ryzen 7 5800x Voltage Problems – Voltage Spikes

The Ryzen 7 5800X is a fantastic processor for gaming and serious work, but like any high-performance tech, it can have its quirks. Voltage spikes, where your CPU’s voltage shoots up briefly for no obvious reason, can cause instability or just make you a bit nervous. Let’s learn why this happens and how to manage it.

Zen 3 Voltage Behavior

The first thing to know is that voltage spikes are somewhat normal on Ryzen 5000 series CPUs (Zen 3 architecture). Here’s why:

These CPUs aggressively push performance, automatically raising voltage when needed. This leads to quick jumps that might look scary at first. Sometimes, it’s the software reading the voltage that’s a bit overzealous, not the CPU itself.

Is It Actually a Problem?

Before diving into fixes, let’s see if it’s causing issues:

  • If your PC is randomly crashing or freezing, especially under heavy load, voltage spikes might be the culprit.
  • Extreme voltage spikes can lead to overheating. Keep an eye on your CPU temperatures using tools like HWMonitor.
  • Even if it’s technically harmless, seeing those voltage numbers jump might just stress you out! Totally valid reason to try and smooth things out.

How To Fix Ryzen 7 5800x Voltage Problems

Here’s how to address those voltage spikes:


  • Updating your motherboard BIOS often improves Ryzen voltage behavior and overall stability.
  • Check your motherboard manufacturer’s website for the latest version and instructions.

Curve Optimizer

  • This is a powerful but slightly advanced feature in your BIOS. It lets you fine-tune voltage on a per-core basis.
  • It takes research and careful testing! There are online guides to help, but proceed with caution if you’re not tech-savvy.

Power Plan

In Windows, try switching your Power Plan from “Ryzen Balanced” to just plain old “Balanced.” This can sometimes calm things down.

Keep Things Cool

High temperatures can make voltage spikes worse. Ensure your cooler is up to the task and your case has good airflow.

Final Words

Ryzen Zen 3 processors are designed to be aggressive. Some degree of voltage spiking might just be how your particular chip rolls. If it’s not causing crashes or overheating, it’s probably safe to ignore and enjoy the performance.
