Bluetooth 1 Mar 2010

The mainboard comes with 1 PCI slot, 3 full length PCIe 2.0 slots that operates in PCIe x4 (orange) mode. The red colour slots are either in PCIe x16 (single slot) or PCIe x 8 (dual slot). There are another two PCIe x1 slots on board. The audio codec, dual LAN PHY can be seen on the PCB. To the right is a huge heatsink covering the North bridge and mosfets. Directly below is the AM3 Socket with label Six Core CPU support. Down underneath is the 4 DIMM slots that can support up to 32GB DDR3-1800 (OC).

On the left is the south bridge SB 850. It supports 6 SATA 6Gbps ports. On board we see only 5 with the other as eSATA at the back panel. On the side are orange connectors for external USB brackets. Beneath it are the power on/off, reset switch and front panel connectors.

Missing on the back panel are PS/2 Keyboard and mouse port. In replacement, we have the D-SUB, DVI-D, HDMI and DisplayPort. There is a red CLEAR CMOS button right next to the HDMI port. There is a eSATA port and 6 USB 2.0 ports and 2 GbE LAN ports. To its right is the audio ports and S/PDIF port.
