bigpup could you check this on your Chromebook (see screenshot):
1) shows percentage of max cpu speed, i've messed something with scaling tool in Slacko, max should be 100% and in Bionic is that value
2) shows max and min speed i've messed something in Slacko in Bionic max is 2160000
Edit:
I've found info:
dmidecode -t processor or more precise: sudo dmidecode -t processor | grep "Speed"
Will not only give you a MHz in use but also the Maximum you can push / overclock your CPU to.
$ sudo dmidecode -t processor | grep Speed
[sudo] password for cyrex:
Max Speed: 4000 MHz
Current Speed: 2666 MHz

So PSI show value for overclockers. So maybe should have info about this.
Edit:
More info:

I think that for my processor Max Speed not overclocked should be:
2249100KHz/1024~2196MHz/1024~2.14GHz
I don't know if my N3050 can work with speed of 2.16GHz like in specs. I think Intel divided 2160000 by 1000^2 (not 1024^2) and this maneuver gave 2.16GHz on the paper.
No, i'm wrong look at end of the post. 2.16 is when max_perf_pct = 100%.
Edit again:
Screenshot 2
1) Formula to stress the CPU:
Code: Select all
echo "scale=10000; 4*a(1)" | bc -l &
2) Core 2 load is 100% that give max speed in (3) 2082.500 what is equal to PSI CSoC. And 2160000 (i've setup this value via:
Code: Select all
echo 2160000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 2160000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
divided by 1024 give ~ 2109MHz which is ~ 2082MHz.
3) Show speed of both cores in real time:
Code: Select all
watch -n1 "cat /proc/cpuinfo | grep \"^[c]pu MHz\""
Edit again (my silly brain is burning
)
2.16 GHZ of N3050 when multiplied by 1024^2 give 2264924.16KHz and 92% of this value (taken from max_perf_pct) give 2083730.2272KHz when divided by 1000 give speed at 100% load 2083MHz

I've read my whole comment again.
Aargh! I made a mistake with one another. Memory with frequency.. Divider for memory is 1024 and for frequency is 1000. Shame on me
