"they" didn't tell me, they told everybody:

mid way down the original post:
- NEW: To activate 2 ghz mode run
Code:
echo 1 | sudo tee /sys/kernel/tegra_cpufreq/overclock
echo 2091000 | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq
then run the command to force max freq if you want to use anything intensive
- To always use 2.0ghz mode copy
Code:
echo 1 > /sys/kernel/tegra_cpufreq/overclock
echo 2091000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq
to /etc/rc.local before the exit 0 line
thats the original post, this one we're in came later done by someone else. they left out A LOT of the info from that main page.
It looks like the "run" command maybe isn't permanent and the "always" one is. But don't know. Then how is the overclock removed and put back to normal, which they don't cover.
And I understand what it does but what you're saying is that these cpu changes occur at the bios level and regardless of what you boot into, once any changes are made, the switch initially boots with those settings for everything and its not determined by what you're booting into telling the switch to "overclock" when you run it?
Cause I know for sure, its not like that for everything. I have a Pi4 with 3 different SD cards and each one will tell the cpu/gpu what speed to run when it boots up. One is stock the other 2 are not. The speed is determined by which card I put in. So technically the Pi always runs stock speed regardless which card I put in, but then a few lines in a file changes that, at boot, depending on what is on that file in the card.
So I want to know if it's definitively that way or not for the switch too.
