I am quite embarrassed to open this topic but because I am willing to hold on to my old laptop but I couldn't access and tweak the voltage to my liking - causing it to always thermal throttle all the time. Got suggested by a lot of people to try this out. All options seemed to be locked on both GPU and CPU on Throttlestop and MSI Afterburner.

I'm running Alienware 17 R3 (2015) so exactly the same as the poster's machine
