RB4011 is missing CPU frequency adjustment

My new RB4011 had a setting to change the CPU frequency with the version of ROS it shipped with (6.45.9), but with 7.1b5 that setting is nowhere to be seen. Is there a fix, or will I be stuck with the default speed?

I think it was mentioned that CPU governor will be dynamic. So you should check CPU frequency from time to time (under different loads), chances are that it’ll be different.

Interestingly, I can’t check CPU speed at all either. It used to be in System → RouterBOARD but now that’s gone as well.

In ROS v6 CPU frequency is shown by /system resource print.

I’m using ROS v7.

Right. Nothing remained unchanged …

So where’s the CPU frequency in v7?

It is right there.

Will this be fixed in a future ROS v7 beta release?

I guess you should report that to mikrotik support.

On my device “cpu-frequency” is printed right between “cpu-count” and “cpu-load”.

Wondering why is this still not fixed? Any reason we should not be able to change cpu freq on 4011 & v7 same as we could on v6?

+1
It should be possible to fix this as it was possible to adjust this before. Mikrotik please fix

Tested ROS 7.4 and not being able to set RB4011iGS+5HacQ2HnD-IN cpu frequency
Is it even possible? Is there any support ticket for that maybe? Anyone knows?

Personally I don’t need the full horsepower of this machine so I would like to reduce its cpu frequency (with the hope it will reduce the generated hot) so I really appreciate if anyone has any progress on this.

I’m afraid it can’t be adjusted. Based on specifications at https://mikrotik.com/product/rb4011igs_5hacq2hnd_in I can see CPU nominal frequency = 1.4 GHz
But other equipments like the wAP ac shows at https://mikrotik.com/product/wap_ac CPU nominal frequency=488-896 (auto) MHz
Or https://mikrotik.com/product/rb5009upr_s_in with CPU nominal frequency=350-1400 (auto) MHz

So, just wondering if our RB4011 is, by design, working at 1.4GHz with no dynamic frequency regulation at all. If so, is there any way to raise a feature request?

Thank you!

Report the problem/issue/request to support.
It’s easy like that.

They may respond with a) we know about it and we are not going to change it, b) thanks for reporting, we’ll look into it, c) fix is on the way.
Or something else :laughing:

I guess that Mikrotk want to do some product segmentation if it is not a firmware bug.

I think the CPU frequency on the 4011 is not adjustable, and it was a bug in older versions that is was shown as adjustable.
This “bug” has been “fixed” and now you cannot see or adjust the frequency anymore.

then rb4011 at 1.800 mhz is a beautiful bug

I’ve said before that it is adjustable in older versions and even made tests with nice screenshots.

Maybe it depended on hardware revision or so. On my 4011 I adjusted the frequency and while I did not make measurements like that, I tried to measure power dissipation and I saw no difference. Hence it was my conclusion that it did not change anything (normally you see quite different power dissipation depending on clock frequency).
