"socket 1366 pin missing"に関する回答Lga 1366 socket (B) can be replaced by using a heat gun and removed the same. Just add insulaters around solder areas where heat should not be so solder doesn't melt. socket (B) is solder balls so this action is considered reflow. I have replaced my own and works great. Done this on ASUS Rampage II extreme mother board.
