Free 300-MHz boost for your RPi 4 with Bullseye

Depending on the SoC on your particular Raspberry Pi 4, the latest Raspbian might kick it up to 1.8 GHz:

tl;dr: if the second line ends in "C0T," Bullseye will run on it at 1.8 GHz. Older-production RPi 4s will have a second line that ends in "B0T," and will still run at 1.5 GHz.



I checked all of the Pis I bought over the past couple or three months for a home cluster, and they're all of the C0T variety. Guess it's time to wipe and reload them again to get the speed boost. :)

Jeff got that slightly wrong; it's not the SoC revision but the board revision that determines eligibility. See

My two older Pi4s (B0T chip, 1.1 board) are also happy to run at 1.8 GHz, by the way, with Buster.

...and he acknowledges as much in the comments:

Might need to look at the older RPi 4 I have (not in the cluster) and see if the speedup applies to it as well, and to apply it to Gentoo if it does (pretty sure I'm running 64-bit Gentoo on it).
