Idle measurements with a usb meter on an 5.3v adapter by changing MIN_SPEED and setting GOVERNOR=powersave: 120MHz: 0.28 A 480MHz: 0.28 A 960MHz: 0.29 A 1200MHz: 0.31 A Nothing plugged in, except for a usb wifi adapter (no traffic) which is pulling 0.18 A itself. Maybe i exchange that one...

Is there any source for that claim? I use this OPi mostly headless for music streaming, so storage performance is irrelevant, standby drain is not. Anyway, i will check the idle power consumption with both settings.

The 408000 setting came from the package. I've set the frequencies to this now: MIN_SPEED=120000 MAX_SPEED=1400000

Thank you, that worked! hardware limits: 120 MHz - 1.37 GHz available frequency steps: 120 MHz, 240 MHz, 480 MHz, 648 MHz, 816 MHz, 960 MHz, 1.01 GHz, 1.06 GHz, 1.10 GHz, 1.15 GHz, 1.20 GHz, 1.22 GHz, 1.25 GHz, 1.30 GHz, 1.34 GHz, 1.37 GHz

Yes, /etc/default/cpufrequtils is mostly identical: ENABLE=true MIN_SPEED=408000 MAX_SPEED=1296000 GOVERNOR=ondemand cpufreq-info shows: hardware limits: 648 MHz - 1.01 GHz available frequency steps: 648 MHz, 816 MHz, 1.01 GHz The H3 SoC is rated to 1.3 GHz and was running about that high with the legacy kernel.

Hi, i am running armbian stretch on an OrangePi PC with "-dev" kernel and uboot. This was originally an jessie installation with legacy kernel, that was upgraded. I'm wondering now, why the cpu frequency only scales between 648 and 1008 MHz instead of 408 and 1296 MHz. Is this to be expected? cpufrequtils is configured to the latter. # lscpu Architecture: armv7l Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 Model: 5 Model name: ARMv7 Processor rev 5 (v7l) CPU max MHz: 1008,0000 CPU min MHz: 648,0000 BogoMIPS: 30.85 Flags: half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm armbianmonitor -u: http://ix.io/1xNM
