Overclock CM3?

Hello I've a Slice with CM3. It has cooling system so it runs in standby around 37c and under load at ~55c.

My current config is:

Code

#force_turbo=0
#force_turbo=1
arm_freq=1350
core_freq=500
over_voltage=4
# prevent scaling

So max speed is 1350mhz. According to bcmstat (thanks for the tool!) it is a :

Code

   Board: 4 x ARMv7 cores available, ondemand governor (CM3 rev 1.0, BCM2837 SoC with 1GB RAM by Sony UK)

Has anyone tried with higher settings? These that I have I guess are the default ones delivered by the 5ninjas.

Overclocking instructions for RPi3 are generally applicable for CM3 too. I used to run some moderate OC with my Slice box, though that's so long ago now that I can't recall the actual details of the options used.
