RAM overclocking #286

Open bodeni opened 5 years ago

bodeni commented 5 years ago

Hi! Try RAM overclock following guide: echo 933000000 | sudo tee /sys/bus/platform/drivers/rockchip-dmc/dmc/devfreq/dmc/max_freq tee: /sys/bus/platform/drivers/rockchip-dmc/dmc/devfreq/dmc/max_freq: No such file or directory echo performance | sudo tee /sys/bus/platform/drivers/rockchip-dmc/dmc/devfreq/dmc/governor tee: /sys/bus/platform/drivers/rockchip-dmc/dmc/devfreq/dmc/governor: No such file or directory

CPU overclocking works fine!

Ok, after upgrade to bionic beaver files still does not exist. Actually in /sys/bus/platform/drivers/rockchip-dmc\ path only three files: bind, unbind and uevent... Any suggestion?... uname -a Linux rock64 4.4.132-1075-rockchip-ayufan-ga83beded8524 #1 SMP Thu Jul 26 08:22:22 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

Maybe try a sudo find / -name max_freq to see if you can find it elsewhere on the system.

Only for GPU: /sys/devices/platform/ff300000.gpu/devfreq/ff300000.gpu/max_freq
