AMD Ryzen 5000 undervolten: This is how the CPU becomes quieter and cooler The CPU knows its limit Less performance, high consumption Undervolting with offset Undervolten with the Curve Optimzier Easier, economical and quiet: The eco mode Conclusion table Of 20 on 90 degrees in a few seconds despite good cooling: under full load, some Ryzen 5000 as a veritable heating plate. Even if AMD regards these high temperatures as safe and the processors meticulously adhere to this maximum limit, in the end it means at least louder fans and, in the worst case, loss of performance due to throttling.

Ours, with still moderate 105 watts TDP specified, Ryzen 7 5800 X does not even get a water cooling confidently captured as soon as maximum performance is required from all eight cores. This is surprising insofar as the Ryzen processors based on the Zen 3 architecture are quite efficient and should run as close to their optimum as possible without user intervention. But the repeatedly unmistakable fan noise raises the question: Can AMD’s tuning be improved?

The Ryzen processors from AMD are inherently fast and efficient, but with a little experience you can squeeze a little more performance out of them.

In order to get a cooler processor without loss of performance, we concentrate particularly on the so-called undervolting: The CPU is operated with less voltage, which results in lower power requirements and thus should lead to less waste heat. Our test system consists of the Ryzen 7 5800 X and the mainboard Gigabyte X 570 Aorus Master. Its beta BIOS F 31 l already offers the “Curve Optimizer” promised by AMD, which, among other things, should make it easier to adjust the voltage.
