Carrizo products will be compatible with socket FM2+ motherboards, built around A78 and A88X chipsets. My motherboard has A55, so thats why its not supported. Problem solved.
I totally forgot, I have rev. 3.0 which says that it supports FM2/FM2+ sockets. But in cpu support list I cannot find 845 one, 860k; 870k; 880k and even 840 are there. Is this a mistake?
