i have upgraded armbian on tinkerboard asus form 5.35 to 5.38.  And this changed cpu governor to conservative. I have changed it to performance. BUT previous max cpu speed was 1.80GHZ and now i have only 1.61.GHZ I have cooler with fan on my tinkerboard and iam not scared high cpu temperature. Hov to get back to the maximum 1.80 GHZ frequency ???? I cant add 180000MHZ via sudo nano /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies to each core permission deni
