I have an old Processor Intel® Core™2 CPU T7200 @ 2.00GHz × 2 Why is the current frequency stuck at 1GHZ if the CPU is built for up to 2GHZ?
Here are the frequency #s when I run the following script
root@imparoUbuntu-ThinkPad-T60:~# paste <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_min_freq) <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq) <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq) | column -s $'\t' -t
1000000 1000000 2000000
Min Current Max
1000000 1000000 2000000
1000000 1000000 2000000
Also please see "current policy" below:

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1000 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance, schedutil
**current policy: frequency should be within 1000 MHz and 1000 MHz.**
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1 GHz.

PS: I already changed governor to "performance" but current policy keeps frequency range at 1000 MHZ for both min and max despite the CPU being built for 2Ghz
