Hey,

Ok. I'm new to rpi4= and arm in general but tomorrow I will force 'arm_freq=3D1800' aga= in just to see it it crashes again.
I will check too what values = linux shows.

I don't know if firmware/uboot ve= rsion included in 12.3 supports this feature.

Chee= rs,

Hi Nuno,
I'm not sure where to start - I just happened to notic= e in the documentation here:=C2=A0https://www.raspbe= rrypi.com/documentation/computers/config_txt.html that the cpu frequenc= y Pi4B R1.4 was listed as 1800 if arm_boot=3D1 so I tried it.
Doug.

Hello Doug,

I have too a 1.5 rpi but arm_boost=3D1 isn't doing any= thing, htop shows 1500Mhz when doing something intensive.
I'm= running 13.2 stable

Do I missing something?

Could you take a look at my setup?
