Is it safe to set the max CPU frequency?

[interfaSys]

powerd seems to work fine, I can see it adjust the clock when I'm monitoring it in the shell, but my CPU's burst clock is 2.08Ghz and the limit in OPNsense is set at 1.6Ghz.
Is it safe to set it right?

You can see the artificial limit being set in "dev.cpu": 1601/2000 1600/2000 1520/1900
The burst mode is disabled.

It turns out the 1Mhz difference is there to signify that Intel Turbo Boost is enabled...
