| From my testing on clocks on the Pi 5, it looks like the default
| clock of 2.4 GHz is pretty close to the sweet spot for this chip
| (BCM2712), and you burn a lot of power for small incremental
| gains after that[1]. (Which you seem to also show with the 3.3
| GHz overclock!).
|
| I also spoke to one of the Pi engineers about the chip behavior
| at higher clocks, and he suggested unlike some chips, this chip
| might run more stably at higher temperatures (like 50-60degC)
| rather than 'as cold as you can get it'. So that poses some
| challenges since most cooling solutions aren't tuned for 'keep a
| temperature' but instead 'get it as cold as possible', without a
| lot of manual tweaking.
