Ok, I fixed this just now. Here's how:
Terminal (Alt+F2) > sudo thunar (replace thunar with your file-manager)
> / > sys > devices > system > cpu > cpu0 > cpufreq > scaling_min_freq
> edit to the lowest value you want (800000 in my case) > save > ignore any failure errors > exit thunar
> back to terminal > cpufreq-info
TADA! It should be done now. In case you need to edit you maximum scaling frequency, replace Scaling_min_freq with scaling_max_freq.
