My device runs at 125 - 1000 24-7-365. When it's not processing, drop the CPU speed to the lowest possible number, in this chips case, 125Mhz.

The risk (as with any adjustment of vCore) is instability. What is a greater risk is INCREASING vCore to get higher stability which generates more heat through the resistance of the CPU - but DECREASING vCore will increase battery life (lower voltages = lower pull on resource, resource being battery) lower the temperature of the CPU, but may affect the stability of the device as the square waveform running through the CPU has a chance of degrading.

What will happen is the device reboots. Thats it. Call it a risk if you will, but it's nothing I would be overly concerned with. If you do get a random reboot, then the device will load stock kernel configuration with 250 - 600 limits, as this is a safety net built in to the code of kernel-power.

YES, IT IS SAFE.
