Nominal CPU frequency is 1700MHz. But it’s possible to overclock it by setting /system/routerboard/settings set cpu-frequency=. Nowdays default setting is auto which allows ROS to scale frequency up or down depending on CPU core load. Sometimes this doesn’t work too well (it takes sone time to scale up and during that period of time router performance lags somehow).
I checked it, winbox doesn’t show that option.
CLI kind of the same:
[admin@x] /system/routerboard/settings> set cpu-frequency=1700
input does not match any value of cpu-frequency
[admin@x] /system/routerboard/settings> set cpu-frequency=2000
input does not match any value of cpu-frequency
[admin@x] /system/routerboard/settings> set cpu-frequency=auto
input does not match any value of cpu-frequency
[admin@x] /system/routerboard/settings> set cpu-frequency=
[admin@x] /system/routerboard/settings>
Running export doesn’t show any changes to the default.
Also check settings in /system/device-mode … I think you have to enable routerboard property to change cpu frequency setting … just don’t know which particular ROS version started to require that (could be it’s 7.17).
