    It is possible that 130mV is not enough for the CPU to operate, so I suggest you to try increasing to -120mV. If the computer keeps restarting after that, increase it a bit more or try removing the undervolt to find out if this is what is causing the unexpected restarting.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    You have undervolted the processor too much. How much have you reduced the voltage by?

    Hi! Well I used XTU to decrease temperature with undervolt CPU. So I made an 5 minute stresstest with original settings and after with -0.110V. Test passed and CPU temperature changed from 73 C° to 65 C°. Predator Sense showed last time max 91 C° CPU and 85 C° GPU degree (playing with World of Warships, graphics optimalized by NVidia GeForce), now show CPU 78 C° max and GPU 74 C° max, so I'm totally satisfied. My configuration is Predator Helios 1060 GTX and i7-7700HQ.
