The mainstream models will replace the current LGA1156 'H1' Clarkdale and Lynnfield CPUs (Core i3 and Core i5) and will use LGA1155 'H2' packaging. Yes, that's right, LGA1155 - one fewer pins than current LGA1156 CPUs. These sockets are NOT compatible, so you cannot use an existing LGA1156 CPU in a new motherboard or visa versa. Not only is the position of pin-1 different, the socket notch has moved from 9mm to 11.5mm from the centre and the entire voltage plane layout has changed ...
