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?
Re: RB4011 is missing CPU frequency adjustment
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.
Re: RB4011 is missing CPU frequency adjustment
Interestingly, I can't check CPU speed at all either. It used to be in System -> RouterBOARD but now that's gone as well.
Re: RB4011 is missing CPU frequency adjustment
In ROS v6 CPU frequency is shown by /system resource print.
Re: RB4011 is missing CPU frequency adjustment
I'm using ROS v7.In ROS v6 CPU frequency is shown by /system resource print.
Re: RB4011 is missing CPU frequency adjustment
Right. Nothing remained unchanged ...I'm using ROS v7.In ROS v6 CPU frequency is shown by /system resource print.
Re: RB4011 is missing CPU frequency adjustment
So where's the CPU frequency in v7?Right. Nothing remained unchanged ...
Re: RB4011 is missing CPU frequency adjustment
It is right there.

Re: RB4011 is missing CPU frequency adjustment
Will this be fixed in a future ROS v7 beta release?
Re: RB4011 is missing CPU frequency adjustment
I guess you should report that to mikrotik support.Will this be fixed in a future ROS v7 beta release?
On my device "cpu-frequency" is printed right between "cpu-count" and "cpu-load".
Re: RB4011 is missing CPU frequency adjustment
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

Re: RB4011 is missing CPU frequency adjustment
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.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?
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
Re: RB4011 is missing CPU frequency adjustment
I guess that Mikrotk want to do some product segmentation if it is not a firmware bug.
Re: RB4011 is missing CPU frequency adjustment
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.

Re: RB4011 is missing CPU frequency adjustment
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.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.

Re: RB4011 is missing CPU frequency adjustment
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).
Re: RB4011 is missing CPU frequency adjustment
For my part, I had the opportunity to observe the change in performance from stock 1,400mhz to 1,800mhz under heavy load (for that device) in various scenarios like BRAS for 450 subscribers almost 600mbs of peak traffic, and border-router/PCC-load-balancer up to 900mbps
by increasing the CPU clock, effectively CPU usage is reduced proportionally
In another case, with CPU usage maxed Out as a BRAS with around 700 subscribers increasing the CPU clock, effectively increased throughput while still being maxed out
I choose 1.800 MHz as a safe barrier to staying because that kind of CPU core (A15) implementations typically were commercialized around that clock

Re: RB4011 is missing CPU frequency adjustment
My 4011 is already running too hot for my liking (47C core temperature with a small fan besides it) so I certainly would not overclock it...
In fact my objective was to set a lower clock to see if I could make it run cooler. I couldn't.

Re: RB4011 is missing CPU frequency adjustment
I have seen changing the clock from 1.400mhz to 1.800mhz rises temperature only around 2-3 °C in the worst case, with not a single event of instability or reboot.
I have made this change on dozens of 4011
At this level, it can rival ccr1009 in scenarios requiring processing like mangle and queues.

Re: RB4011 is missing CPU frequency adjustment
I would believe Mikrotik wants to lock hardware performance for pricing.
Particularly cpu overclocking.

Re: RB4011 is missing CPU frequency adjustment
If that would be the reason, they could easily limit the range of CPU clocks to the official spec (i.e. no overclocking, only underclocking)...
Re: RB4011 is missing CPU frequency adjustment
Not to mention that there is no “unlocked” RB4011 in the lineup at a premium price.
Do I understand the conspiracy theory’s premise correctly, that we could all just drive our home routers at 2, 3GHz and avoid the CCR line or something?
Lunacy.

Re: RB4011 is missing CPU frequency adjustment
Mikrotik just updated hAP ax² and Chateau 5G ax performance results.
What I've noticed is that they both have IPQ-6010 + 1G RAM(DDR3L or DDR4?) + 128M NAND.
IPQ-6010 on Chateau 5G ax is running at auto (864-1800) MHz ,
but it's running at 864 MHz on hAP ax².

Re: RB4011 is missing CPU frequency adjustment
In 7.7 I can't see evem the cpu speed.
Re: RB4011 is missing CPU frequency adjustment
In a recent test version I can see the momentary CPU speed of my 4011 but it is still not possible to manually set it.
It is usually running at 533 MHz but it steps up when there is load, usually to 1200 or 1400 MHz.

Re: RB4011 is missing CPU frequency adjustment
That is the idea of auto, no ?
Re: RB4011 is missing CPU frequency adjustment
Yes, but in many many versions there was no display of the actual frequency.
Wait, I checked incorrectly. It is now at "auto" but it can again be configured to a fixed frequency between 533 and 1900 MHz.

Re: RB4011 is missing CPU frequency adjustment
I can't found options to set up the cpu speed.
Re: RB4011 is missing CPU frequency adjustment
Wait for 7.8beta1
