T440p running at 798 MHz

[u/drinkuranium]

I upgraded my T440p a couple days ago and installed gentoo, i put a I7 4980hq and 8gb and 4gb sticks of ram inside and also flashed libreboot. Im assuming its thermal throttling but after compiling for a while it sits around 80-90 degrees at 3 ghz or higher then it drops right down to 798 MHz and 50 degrees, im not sure how to fix this or why its happening but i have sufficient thermal paste and even after an hour of 50 degrees it doesnt fix or go back to regular speeds, and rebooting doesnt fix the issue.
