The Gigabyte GA-P55-UD3R is an ATX format motherboard supporting Intel LGA1156 format CPUs. This is similar to the Gigabyte GA-P55-UD3L, but has expanded RAID support and 2 eSATA connectors. The serial and parallel ports have been removed as well. Otherwise they are very similar, with 4 DDR3 sockets supporting up to 16GB of memory and 6 SATA connectors. RAID support allows for RAID 0, 1, 5 and 10 configurations, enabling the motherboard to be used in a home server. Built-in 10/100/1000 Ethernet allows for a fast network connection. On-board audio support is provided in the form of a 7.1 surround sound high definition system that outputs to a coaxial or optical S/PDIF out connector. Up to 14 USB 2.0 ports are supported as well.
