[solved itself] cpupower doesn't scale ivy bridge high enough

Question

Not sure if I should have put this in the testing section, the kernel section or here. But I try here.
cpu family : 6
model : 58
model name : Intel(R) Core(TM) i7-3632QM CPU @ 2.20GHz
My problem is:
$ analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.20 GHz
available frequency steps: 2.20 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.40 GHz, 1.30 GHz, 1.20 GHz
available cpufreq governors: userspace, conservative, ondemand, performance
current policy: frequency should be within 1.20 GHz and 1.60 GHz.
The governor "conservative" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.
boost state support:
Supported: yes
Active: yes
"current policy: frequency should be within 1.20 GHz and 1.60 GHz."
Why is the maximum of the current policy 1.6 GHz and not 2.2GHz? cpupower knows it can scale up to 2.20GHz. i7z confirms that it never clocks above 1.6GHz when running stress -c 1.
So to make sure no automatism screws with it:
$ sudo cpupower frequency-set -g userspace
$ sudo cpupower frequency-set -f 2.20GHz
But still:
$ cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.

available frequency steps: 2.20 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.40 GHz, 1.30 GHz, 1.20 GHz
available cpufreq governors: userspace, conservative, ondemand, performance
current policy: frequency should be within 1.20 GHz and 1.60 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 1.60 GHz.
boost state support:
Supported: yes
Active: yes
It won't go above 1.6 GHz.
What can I do to convince it to clock to the maximum frequency, and to use "turbo boost" when appropriate?
Edit: I have since rebooted again and this time I see this:
$ cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7
CPUs which need to have their frequency coordinated by software: 0

available cpufreq governors: conservative, ondemand, performance
current policy: frequency should be within 1.20 GHz and 2.20 GHz.
The governor "conservative" may decide which speed to use

current CPU frequency is 1.20 GHz.
boost state support:
Supported: yes
Active: yes
So at least it does clock to the official maximum. i7z doesn't show turbo boost though. Is it a i7z limitation for ivy bridge?
edit2:
After another reboot it works completely. Weird.

Answer 1

Probably same issue here, cant switch frequency at all. At some point it worked, now doesnt work at all. Tried to use Jupiter, but it was unable to change anything when started automatically, so when I removed it from autostart it started to work, but only for 1-2 reboots.
I'm using Core i5 CPU.
Edit:
After suspend it behaves like ondemand, but still very strange behavior + I cant change XFCE settings on acpi events.
Edit again:
I installed jupiter again, but this time i added ROOT user to group jupiter instead of adding it only for my user. Now it works! Switches correctly. 4 reboots. But when closing laptop lid it still goes to sleep instead of black screen....
Try unchecking "Monitor power management control" in power settings if using XFCE, maybe it helps too. My advices!
