?If the CPUs and other parts on the SoC have nothing to do, so use-case 'idle'To underclock by limiting the max frequency, one of the Engineers said there is no point in going lower than its base frequency as there is no difference in power usage. That was within the past months.
But fix max clock to 1500 and let the Pi do something, like compiling a mainline 6.16 kernel for example. Keep your fimgertip on the SoC metal all the time.
Of course using it will use more power. Just on about underclocking lower than 1.5G is near pointless if looking for idle power saving.
Limiting or increasing the top frequency (overclocking beyond the default settings) is a different thing.
