Adjust voltage settings on a Ryzen 5 2400G for better performance and efficiency.
Adjust voltage settings on a Ryzen 5 2400G for better performance and efficiency.
I possess a Ryzen 5 2400G setup with an ASRock B450M Pro4 board and no graphics card. I began adjusting the processor voltage long ago at 1.25V (stable), now aiming for further reductions. I've explored various methods—ZenStates, BIOS settings, and manual tuning—but the core voltage keeps rising to 1.25V according to ZenPower. When I adjusted via BIOS, it still returned to 1.25V, and even after using ZenStates, the output remained unchanged.
Here’s a summary of my attempts:
- Changed CPU frequency and voltage settings in the BIOS (manual mode, 3600Hz, 1.225V).
- Ran ZenStates with voltage set to 1.225V and frequency unchanged.
- Followed the provided command line instructions for ZenStates.
The output from ZenStates after both BIOS and ZenStates adjustments showed the same result: core voltage stuck at 1.25V.
Regarding your questions:
- Are you applying the steps correctly? Double-check that you’re using the right commands and saving them properly.
- As for the maximum achievable undervolt, it depends on the chipset and motherboard capabilities. Most modern Ryzen processors can typically be reduced to around 1.0–1.1V under stable conditions, but this varies widely.
- If you're curious about performance limits, expect gains only if the voltage reduction is significant enough and the system remains stable.
Please let me know if you need further clarification or troubleshooting steps.
