[ 0.049094] smpboot: CPU0: Intel(R) Celeron(R) CPU J3355 @ 2.00GHz (family: 0x6, model: 0x5c, stepping: 0x9)

It's in fact 2.5Ghz and was recognized as so in old ARPL.

Is it still 23.7.5?
You can try 23.8.1 and the modules in 23.8.1 add back cpufreq_performance.ko Library.

It's 27.8.0. I'll try 23.8.1. сб, 5 авг. 2023 г. в 08:41, Ing ***@***.***>:

On 23.8.1 cpu freq is detected correctly. Thanx!
