What are the valid values?
1500 keeps getting rejected, and I dont ahve a serial cable to figure out whether the boot monitor shows the values. THe terminal does not… So, what can I enter there?
You first have to adjust RAM clock speed, in order to be able to set CPU clock to 1500 MHz.
RAM Clock speed adjustment is also done in /system routerboard settings menu.
Good. Can you give me valid numbers there? as in: I am totally lost WHAT NUMBERS to enter for RAM Sadly this little menu does only say “invalid” and not “ok, these are valid numbers”.
Try
/system routerboard settings set memory-frequency=?
THat worked - got me a nice list of possible values. Thanks.
