The tool supports undervolting the CPU by configuring voltage offsets for CPU, cache, GPU, System Agent and Analog I/O planes. I suggest you to use the excellent s-tui tool to check and monitor the CPU usage, frequency, power and temperature under load! Undervolt Is this tool really doing something on my PC?

#CPU THROTTLED INSTALL#
The install script was updated, but please report back if anything breaks. The latest commit () switched from the legacy name lenovo_fix for the tool/config/system to a more uniform throttled.
On systems where the EC doesn't reset the values (ex: ASUS Zenbook UX430UNR), the power limit can be altered by using the official intel_rapl driver (see Static fix for more information) Warning! The CPU package power limit (PL1/2) is forced to a value of 44 W (29 W on battery) and the temperature trip point to 95 'C (85 'C on battery) by overriding default values in MSR and MCHBAR every 5 seconds (30 on battery) to block the Embedded Controller from resetting these values to default. This tool was originally developed to fix Linux CPU throttling issues affecting Lenovo T480 / T480s / X1C6 as described here.
