7800x3D BIOS Optimization


I saw this video of a guy optimizing the BIOS for a 7800x3D on a X670E Taichi:

Sadly he doesn't elaborate on all changes he did, so I noted down the full list in hopes others have input.
I use my PC solely for browsing and gaming. Only devices hooked up is keyboard, mouse and a Xbox controller.
7800x3D, NH-D15, B650 Taichi Lite, 2x16Gb, 6900XT, 750W SuperNova P2, Win10.

    Why disable cstates the power supply setting shouldn’t change anything either and I doubt changing llc settings truly offsets unstable systems

    You changed so many settings without even testing your co per cores lol
