ALL CPU's stuck at 800Mhz ubuntu 20.04.3

Cpu's all stuck at 800Mhz

I type in watch -n1 "cat /proc/cpuinfo | grep MHz" (to see cpu's)

No matter what I do, I launch a large program and render an animation in Blender or use Octave to crunch numbers the CPU's don't go past 800Mhz

 rt@sys76:~$ cpupower frequency-info --policy
analyzing CPU 0:
  current policy: frequency should be within 800 MHz and 2.40 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.

Here is how you can make your CPU go at max speed:

Make a file named cpumaxspeed.sh or any name that you like and enter in this code:

#!/bin/bash
#Getting and setting variables

echo Getting info....

CPUMIN=$(cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq)
CPUMAX=$(cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq)
CPUMAXGHZ=$(echo "scale=1; $CPUMAX / 1000000" | bc)
CPUMINGHZ=$(echo "scale=1; $CPUMIN / 1000000" | bc)

#Display min and max CPU frequency in MHz
echo CPU min frequency: $CPUMIN" MHz" / $CPUMINGHZ" GHz"
echo CPU max frequency: $CPUMAX" MHz" / $CPUMAXGHZ" GHz"

#Setting CPU governor
echo Setting governor to performance
sudo cpufreq-set -r -g performance
echo Set governor to performance

#Setting to max frequency
echo Setting CPU frequency to be $CPUMAX" MHz" / $CPUMAXGHZ" GHz"
sudo cpufreq-set -r -f $CPUMAXGHZ"GHz"
echo Set CPU frequency to $CPUMAXGHZ"GHz"

done

To execute the file run this command:

sudo sh yourfilename.sh

Replace [yourfilename] with the name that you entered.
