Shunt Mod - Laptop Modding Adventure - Part 4

Описание: Laptop Modding Adventure: Part 4

This one is all about shunt modding! I will talk a little about the silicon quality and how shunt mods work. Finally I will show you how I shunt modded this laptop and what it meant to the performance and temperatures.

The goal of this series still is: An RTX 2070 mobile with 125W and 140W TGP with a ton of documentation and (i hope interesting) data plots.

Hope you enjoy me burning some money ;) Let's hope I succeed.
