It stated that r44719 is one of the favourate built (perhaps is more stable)?. What would be the major advantage of upgrading to the beta 18.11.21?
44719 is old and has security holes...always good to read new builds threads, as well SVN line... and run last builds...usually the last builds have fixes and ect.
There is not such an animal as a 'stable build'....its stable for one, but not stable for someone else, it depends what kind of set up you run on your router... _________________ Atheros

One line will work if you do not make typos.
Typos are hard to spot in one line.
If you just copy paste it it will work but when typing there is a difference between // and ||
The rule "must" be used together with:
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
Otherwise the router is really slow.
Does it harm to run at full speed?
I do not think so the router runs really cool even at full speed.
Does it save power?
In theory yes, in practice minimal.
Does running at all the time at full clock speed would not reduce the life of the router?.
No, the CPU governor and ondemand scaling is primarily a power saving function.
However, the differences in this CPU are marginal, only a few milliwatts difference whether the CPU runs at 800 or 1700Mhz.
CPU's are also designed in principle to run at full clock speed and throttling is unnecessary.
Besides, this is a smartphone CPU, the cores are the same as in the Snapdragon S4 pro.
With the difference that they cannot be cooled properly in a smartphone - hence the thermal throttling
In a router like the R7800, the CPU has a massive 5mm thick metal plate as a heatsink.
Even under full load for 30 minutes, the CPU rarely reaches 65-70°C.
therefore scaling and thermal throttling is absolutely not necessary and superfluous in this router.

Yes, there was a typo in the OP. That is why I quoted the thread with the correct text. The other method will work if there are no typos. Sorry for the confusion, if any. This is how I have it entered in my R7800:
Code:
for CPUGOV in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;
do [ -f $CPUGOV ] || continue;
echo -n ondemand > $CPUGOV;
done
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

You have to save that as a startup script; it may or may not work via the web shell due to syntax or some other anomaly. This is meant to be saved as a startup script, not run on the fly. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

That's perfect I wasn't sure if I could test the code before saving as start-up. That's a great pdf you have I keep coming back to it for updates. Thank You
