Dynamic PX. Higher frequency. More stable operation. Lower temperature. (Patreon)
Content
This video compares Dynamic PX with the stock BOOST performance.
HWINFO logging allows to show the dynamics of frequency change, from 4850MHz (base for PX MID) to 5000MHz (peak) on 4 threads.
Why can't CO do that? CO always works at standard voltage, it affects the telemetry values of the processor (cheats), due to which it achieves an increase in frequency. That is, you can get a significant increase in frequency, but the processor will not become cooler.
Dynamic PX works a little differently. My research showed that for Zen 3 silicon the voltage sweet spot is in a completely different range. The voltages should be lower, much lower than AMD suggests. Also the lower temperature of the silicon allows it to run more stable due to reduced static leakage currents. No self-heating which starts a chain reaction (temperature - > add voltage -> temperature). Second, I use completely different bias values for telemetry, which allows to go beyond the limitations of CO.
Another advantage of the dynamic profile is that the frequency will be lowered if necessary. This avoids the crash.
