#CPUFREQ PERFORMANCE UBUNTU 18.04 DRIVER#

Setting the frequency under performance or userspace governers has no effect. I am stumped as to how the CPU MHZ can drop like this, it's not overheating or over using I am logging temp and utilisation.

set the governer to both performance or userspace.

disabled the intel_pstate driver and verified that acpi-cpufreq are running.

Even reboots don't restore the MHz, only driving to the data centre and powering off the server for 10 seconds or so restores to 800 MHz (Idling clock speed). So I have this Dual Intel Silver 4116 CPU server that will set the MHz to 132 randomly, the server becomes unusable after that point.
