The RK3399 Overclock/Undervolt/Voltages Thread

[generaleramon]

Sounds good!  It is expected that reducing the thermal pad thickness, using a copper shim, would result in better heat transfer.

i'm compiling a lot recently and i noticed that the red led blinks sometimes, do you know if it is just temp related or it can be an over-current protection? The SoC is now drawing 11W+ and almost touching 75c

Btw, this is my .dtsi at the moment. Running 1704Mhz / 2208Mhz / 1100Mhz and stable i'm pretty sure that ram bandwidth is holding the SoC back now
