i placed a piece of thermal pad between the shield and the backcover now to press it down and be sure to have more contact, i'll report back after compiling the kernel again. i can't believe that it needs more than that, BUT, worst case, i'm gonna put some thermal glue and a real heatsink on it an call it a day
NEWS: i found out how to overclock the CCI(CCI-500,CoreLink Cache Coherent Interconnect, so it works like the infinity fabric in AMD Ryzen CPUs).
in the rk3399.dtsi file "cru ACLK_CCI" is set to 600Mhz (Thanks to this GitHub Commit), i upped it to 800Mhz and i instantly gained 150-200MB/s in memcpy(3550MB/s) and memset(8200MB/s).
The entire SoC should benefit as the CCI manage all the data flow and cache/memory coherency. Still no idea if it is 100% stable and if i can push it more, i need time
.
This little RK3399 is becoming a beast
