First of all the simple observation from the RT-N66U device:
After update of the firmware the overclocking need to be set once via nvram set clkfreq=662,331,165 and nvram commit - and it will survive the restart (hard and soft - see below).
Otherwise the default values of clkfreq=600,300,150 are used.
Now the more complex (and important) behavior on the RT-AC68U device after the update to the version 378.56_2:
I have set the desired overclocking in the init-start script via nvram set clkfreq=1200,666 and nvram commit to overcome the lock-down of the current Asus firmware.
After a hard reset (power toggle) the settings force the CPU to the overclocking performance:
And the nvram show | grep clk shows: clkfreq=1200,666 - same as the web interface (reading the same value).
But after a soft reset (reboot button in web GUI for reboot command via telnet) the CPU performance is at default speed settings only:
But still the nvram show | grep clk shows: clkfreq=1200,666 - which is not the true speed!
Conclusion: if you want your router to run faster, do not forget to set the init-start values and always do a power toggle in case you need to restart it!
Update:
Over night the NVRAM variable was reset to clkfreq=800,666 - looks like something is re-reading the CFE values and updating the NVRAM settings...
But the good news is that BogoMIPS : 2398.61 shows that it's still overclocked.
With kind regards
