WebOct 3, 2024 · This is the cause of “Unable to determine CPU Frequency” errors. cpuinfo_max_freq is populated by the cpufreq driver used for frequency scaling—that is, making the CPU run faster or slower depending on power-saving settings. Naturally, frequency scaling is not typically permitted in virtualized environments, because each …
WebAug 2, 2008 · Re: CPU Scaling. It's only 2-3 Watts difference and that has to be mostly due to the reduced VCore needed at the lower frequency as power is proportional to frequency but proportional to the square of voltage, so the voltage has a greater impact.
