Problem with GPD G1

[Ghost Defense]

Hi everyone, I use my Gpd g1 with my Legion Go, set to 30W tdp efficiency mode, fan at maximum and in the BIOS the VRam on Auto.. CPU boost turned off.. often when I activate lossless scaling (X2 or X3), the Lenovo Legion Go sometimes suddenly switches off completely after a few seconds or minutes.. does anyone know why this is happening?
