To overclock the VIM3 certain modifications must be made, these involve:
- updating the dtb and kernel to add these new frequencies
- make sure cpufrequtils in your linux system adapt to these new higher frequencies and modified cpu governer
some notes about the overclocking: voltage in the opp table exceeds the recommended maximum 1.04v as per the amlogic A311D datasheet, this doesn't mean any immediate damage will incur to the CPU as it if you further investigate in the dtb, the maximum permitted voltage is 1.05v
