It is wired to two DIMM slots, supporting up to 16 GB of dual-channel DDR3-1600 MHz memory; and a PCI-Express 3.0 x16 slot. The Intel B75 PCH gives out one SATA 6 Gb/s, and three SATA 3 Gb/s internal ports on the B75IA-E33. Display connectivity includes DVI, D-Sub, and HDMI. Other connectivity options include 6-channel HD audio with 7.1-channel optical SPDIF (TOSLINK) output, four USB 3.0 ports (two the rear panel, two by headers), gigabit Ethernet, a number of USB 2.0 ports, and mouse/keyboard combo PS/2 port.
