Hey there, newcomer! I see you're curious about AMD CPUs and their voltage behavior. Let's break this down:
1. The load voltage you're seeing (around 1.013V) is typical under normal operation, especially with PBO disabled. It's generally safe for most workloads.
2. With PBO off, the system tends to run hotter under load, which can cause fans to spin faster temporarily. This is normal and usually not a problem unless temperatures spike.
3. Ryzen Balanced with 85%-100% usage is fine for most tasks, but if you notice instability or overheating, turning PBO back on might help.
Keep in mind, what you're experiencing could be normal for your current setup, but always monitor temperatures and performance. Let me know if you need more details!
These readings don't look correct; the voltage should be around 1.35v to 1.4v when under load. The software you're using is likely affecting the measurements. Undervolting isn't harmful as long as clock speeds remain stable and the system runs smoothly. Voltage spikes are normal if you check the CPU usage graph frame by frame—they usually peak briefly before returning to baseline.
I clarified why the performance is that low by turning off PBO, which was set to AUTO. The voltage now sits between 1.35V and 1.4V. After disabling it, the drop was noticeable but there were no issues—no freezes, no BSOD, and everything functioned normally. The CPU reached a maximum of 3.59GHz without boosting to higher frequencies, and it seems safe to continue using this configuration. Reducing voltage helps lower heat and can extend the CPU's lifespan. PS: I’m using HWInfo64, which closely matches Ryzen Master’s readings.
In short, lower numbers mean performance was better than before, which is a concern. Ryzen2 runs on a smaller chip size than 12nm or even 14nm, so as chips shrink voltages drop. Modern processors occasionally adjust speed to balance heat and performance, which can be tricky to track. This trend started with older CPUs like the Centrinos. Lower clock speeds reduce heat and boost efficiency, making it possible for chips to run faster only when needed. It’s unlikely you’ll cause damage with lower voltages, and the most likely outcome is just a slight slowdown. Edited March 26, 2021 by Bombastinator
Well i can make them to be 1.35V -1.4V but then the temp and voltage SPIKE every damn minute or every damn MOUSE MOVE so yeah ... i disabled it and the voltage dropped to that ... but im still confused if its safe or not for the CPU also i noticed that with PBO disabled and XMP enabled games crashing .... gues that low CPU voltage is not enough for XMP ? and if i want to use XMP i need to enable PBO ?
Generally you can’t easily break anything unless you intentionally remove protections, which usually only occurs in very intense LN2 overclocking scenarios. This isn’t a simple task and often demands installing unique firmware that isn’t widely accessible. Modern CPUs tend to limit performance if they reach their thermal limits, and some laptops even operate in that manner continuously. Spending time at those high temperatures can be risky.
Personally I would manually overclock of you aren't going to use PBO. If you stay within the proper efficient frequency range you can run at very low voltage while still getting decent frequency. Usually there is a point where you have to increase the voltage significantly only to get a few extra hundred megahertz. I know for the old r7 1700 it was 3.7ghz. If you went any higher it would dramatically increase voltage requirements. For the 2700x i believe it was 4.0ghz. As for the 3600 I am unsure but you could probably figure that out with some tinkering.
The readings under load with PBO turned off and C-state disabled seem normal. You're not experiencing any issues, though you're feeling uneasy about it. The spikes in voltage and temperature during browsing are likely due to the Ryzen architecture, but overall it appears stable.
Low voltages keep your hardware safe. The main risks are system stability and possible crashes, but those won’t damage anything. If you require a fully stable setup, it could be a concern, though testing stability would help confirm. For pbo and higher voltages, the system usually adjusts to safe limits without harming components. You might notice increased CPU fan activity for better cooling.
