(09-22-2018, 06:24 PM)Takenover83 Wrote: How is your stability/temps at 2/1.5GHz? My plex server sure could use that extra gear.

OK - got my new heatsink - will post details in the heatsink thread. But more importantly it is an improvement from Pine64 30mm job  - now running 2.1/1.5GHz with no throttling running sbc-bench -T 70 at ambient 23C. (In the past days since you asked have not noticed any issues when running at 2.1 - but also spend reasonable time running stock 4.4.138 kernel to get sound.)


Code:
# ./sbc-bench.sh -T 70
Thermal efficiency test using /sys/devices/virtual/thermal/thermal_zone0/temp

Installing needed tools. This may take some time... Done.
Checking cpufreq OPP... Done
Heating SoC from current 70°C to 70°C. This may take some time... Done.
Executing cpuminer. This will take 5 minutes... Done.

PS - @ddimension - many thanks for 4.18.10 update. BTW I am no expert but do things very differently to your README:
1) unzip
2) restore a .config
3) edit dts and dtsi as appropriate
4) make -j6 bindeb-pkg
5) cd ..
6) dpkg -i linux-image...

Which also means I can remove with dpkg -r or synaptic
