RB4011 wont run at default CPU frequency

RouterOS Beginner Basics
1

RB4011 is set on 533 CPU clock, I’m trying to set to different value (auto) but it’s shows an error.
The error is : couldn’t change settings- not allowed by device-mode (6)

How to get rid this message and to get higher speeds on this unit ?
I updated to most recent beta to try with.
Thanks!

Your best bet for reliability is to not change the factory default CPU clock speed settings.

If you increase the CPU clock speed , it may run a little faster but … It will run hotter and also not as stable.
If you decrease the CPU clock speed, it may run slower and cooler … however there also is a chance it may not be as stable.

All of the devices on a computer board have parts that are rated to run at a maximum bus speed. When you increase the CPU clock speed, there is a chance of the CPU or other parts on the CPU bus of now having a shorter operational life or possibly bricking the entire unit.

You’ll have to update Device Mode with the “routerboard=yes” setting.

If I understand DDM he’s trying to set frequency to “auto” … which is default since around 6.47.

@DDM: read about device mode … in particular, you’ll have to enable routerboard property (i.e. set it to yes).

Edit: meh, have slow fingers

Thanks for the answers!

So, I tried but seems that I cannot do it properly. It doesn’t work for me. Where I am wrong ?

First enable changing of routerboard settings in device mode.
This will require a reboot.

Then you can change the setting.

Okay,
I tried

/system/device-mode/update mode=advanced

then it showed counter and to press reset button/ to unplug the power.
Once I tried with reset. and once removing the power cord.
But after the reboot - shows same error (6) when I’m trying to get access to Routerboard menu.

You need:

/system/device-mode/update routerboard=yes

It worked!
Thanks a lot!
