Is this undervolt working?

[_Pedro_]

Hello there i have an Aorus 15p xd with i7 11800h and rtx 3070 laptop, I wanted to make an undervolt but shortly after there were a lot of crashes even tho there were no errors in TS bench( I put it on infinite and left it for 20min) I unlocked undervolting via modyfing bios with grubx64.As a last resort I installed clean Bios version and now Im wondering if the undorvolt was causing the issue or was it some kind of Bios issue.
