@emilyyoung Oh man. Thank goodness I bought a B650 before the price creep. $700CAD for the ASUS board is painful.

Your rig is basically my iPhone 13 Pro Max saga, I spent nearly $2600 trying to un-lemon my 13 Pro Max and it's ALSO critical to my content creation plans. I had similar mistakes, just to Apple iPhone repair and how it should be done. It was a costly mistake.
