Hi guys, my Logic board is dead so i'm going to look at getting a new one on ebay most likely. My question is , The current board is a 630-9399 LTC 2009 which has been flashed to 5.1. I need a flashed version as i have a 12 core cpu tray. Do i need to get this exact board or could i get away with a 7A1 661-4996, or maybe there is other options?
