I attempted to do this like a dozen times with my i7/32GB ram 9310. Had a few successful attempts but the board was just fried. Ended up getting an i5/16GB board off ebay. So upset the i7 board crapped out. I had only been using the laptop sparingly for on site work and occasional content consumption and it was only a few months out of warranty when it went to shit.
Been eagerly awaiting this mod since I found my 2-chip in my parent’s attic a year or so ago.
