GB-BACE-3000 Celeron N3000 Speedstep issue

Recommended Posts

Hello,

I am new in here. Reviewing all topics related to Intel Speedstep and couldn't find anything that would solve my issue with nettop GB-BACE-3000 Celeron N3000.

Processor doesn't want to run more than minimal speed 1.04GHz.

I did all checks I found on this forum:

1041000
1041000

It seems Bios limits my CPU freq. By any chance I could set something like:

echo 2000000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

 

I would be grateful for any support.

How did you assess that your CPU is not running above 1.04 GHz? As far as I can tell, the Celeron N3000 CPU's base frequency is 1.04 GHz with a burst frequency of 2.08 GHz.

 

What do you get if you type the following:

sudo dmidecode -t processor | grep "Speed"

 

You can also try this to check the maximum speed of the CPU:

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq 

or

cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq

thanks for your response Polanskiman.

sudo dmidecode -t processor | grep "Speed"

command doesn't work on my nanoboot.

Dysk> cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
1041000
1041000
Dysk>

So this CPU won't run over 1041000, that's a pity :sad:

Have you checked the bios configuration of your mother board see if there is anything limiting the speed?

 

Also run this:

cat /var/log/dmesg | grep "MHz processor" 
 

What do you get?
