My friend needs a new Z77 motherboard. 2 of his ram slots on his current board died. Unfortunately it was slots 3 and 4 leaving him with 1 and 2 and only able to use 8GB of ram and he has seen a sizable decrease going from 16GB to 8GB. He does not wish to upgrade his entire CPU motherboard and ram because he has a I7 3770k. Anyone know where i can located a Z77 for him?
