RK3368 DDR/GPU/CPU Overclocking Voltage/Clock Levels

[Shomari]

Anybody out there running kernels/firmware with overclocked, higher than factory-set values?

I'd like to compare my test values with whatever is out there to get an idea of device tolerances.

So far I can run the following clock speeds with the stock power supply:

GPU: 625
CPU: 1608 - all eight cores
DDR: 810

I'd like to overclock is there a flashable image for rk3368 boxes then?

The goal is to make a universal script for users to change values, kind of like the old RKpathomatic of the RK30/31 generation. For now I need to determine the parameters in the stock kernels you see what's possible.

Want to help test?

I do like to get the most out of these devices, and normally the least effective overclock is the CPU in terms of performance gains. But, I noticed the little cores in the RK3368 are factory set to match voltage with the big cores; and the parameters allow them to scale even higher than the big cores, which defeats the energy efficient functions of the big.LITTLE design. Knowing this, I set out to get the most of those power domains - including every dvfs regulated component, not just CPU.

If I understood development I'd help but I don't understand it.
