Gigabyte has rolled out six mainboard models for Intel’s LGA1156 processors with integrated graphics core. The series is meant to cater to different user categories. It is easy to discuss these mainboards in pairs and we will begin with the two junior models. The microATX GA-H55M-S2H is simpler than the GA-H55M-UD2H. It lacks an additional IEEE1394 (FireWire) controller and there are no eSATA and DisplayPort connectors at its back panel. It also has only two memory slots and is the least expensive product in the series.
