How to stop Power Limit Throttling

Hello! My acer laptop has a 15W power limit on the CPU wich forces it to downclock to 1.6 GHz when under load. I was wondering if there is a way to bypass /disable power limit throttling to stop this from happening. I tried Undervolting the CPU but there was no change.

XTU could let you raise the power limit, if Acer didnt lock it down that is.

 

check your temps

Most throttling issues stem from a gpu or cpu getting too hot

Throttling is not caused by the power limit, it's caused by overheating.

It shows a tool to raise the power limit and avoid power throttling (up to a certain point). I'm not sure if it'll work, but at least it's a start

ThrottleStop is usually the go-to tool for these kinds of issues.
