Xiaomi Mi Notebook Pro Bios Voltage Undervolt Patcher

Xiaomi Mi Notebook Pro Bios Voltage Undervolt Patcher

The newer bios on Xiaomi’s Mi Notebook Pro blocked us out of the Intel XTU voltage setting. Meaning you couldn’t undervolt the CPU in – 0.080 or 0.090 volts to lower temps and increase performance. Well, some Russians have come up with the solution to patch the bios to allow access. This is for bios 0502 and 0603. Mi Notebook Pro only, I would not risk it on the 13″ 8th Gen 8250U and 8550U models you could brick the bios.

Rainfaker in the Xiaomi Reddit r/Xiaomi community posted this the patch here. It’s a simple matter of running a batch file with admin privileges and then restarting it.

Thank you, Brandon, for the info!

  1. Sure!
    Undervolting provides a whole lot of advantages
    – lower power consumption
    – lower temperatures on CPU
    – less/slower fan operation = less noise, less prone to suck dust and get dirty
    – longer battery life
    – less thermal stress on CPU, heatsinks, fan, etc

    I just applied the patch linked above by Chris to mi Notebook Pro i5 Bios 603 and worked perfectly
    After undervolting 100mV system is perfectly stable and temperatures on cores dropped from 75/80 °C with some throttling to less than 70 and no throttling.

  2. Sorry if this question is a little dumb but I might aswell ask here. Does undervolting also increases battery life? Or underclocking and undervolting are not even the same?
