  • Free 300-MHz boost for your RPi 4 with Bullseye

    From Scott Alfter@21:1/5 to All on Tue Nov 9 20:56:23 2021
    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 https://www.raspberrypi.com/news/bullseye-bonus-1-8ghz-raspberry-pi-4/

    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).
