1 Chapter 1 Introducing the Motherboard Introduction Thank you for choosing the A780GM-M3 motherboard. This motherboard is a high performance, enhanced function motherboard that supports socket for AMD PhenomTM processor (socket AM2+)/AthlonTM 64 X2 Dual-Core/AthlonTM 64/ SempronTM processors for high-end business or personal desktop markets. The motherboard incorporates the AMD RS780 Northbridge (NB) and AMD SB700 Southbridge (SB) chipsets. The Northbridge supports the HyperTransportTM 3.0 in- terface. The memory controller supports DDR2 memory DIMM frequencies of 1066 (AM2+)/800/667/533/400. It supports two DDR2 slots with maximum memory size of 16 GB*. One PCI Express x16 slot, intended for Graphics Interface, is fully compliant to the PCI Express® Generation 2.0. In addition, one PCI Express x1 slot is supported. The SB700 Southbridge supports two PCI slots which are PCI v2.3 compliant. It integrates USB 2.0 interface. It implements an EHCI compliant interface that pro- vides 480 Mb/s bandwidth for 8 USB 2.0 ports (4 USB ports and 2 USB 2.0 headers support additional 4 USB ports). The Southbridge integrates a Serial ATA host con- troller, supporting six SATA ports with maximum transfer rate up to 3.0 Gb/s each. There is an advanced full set of I/O ports in the rear panel, including PS/2 mouse and keyboard connectors, COM, one VGA port, one DVI port, four USB ports, one LAN port and audio jacks for microphone, line-in and 6/8-ch (optional) line-out. *Due to the DRAM maximum size (2 GB per dimm) at present, the memory maximum size we have tested is 4 GB. Introducing the Motherboard

2 Feature Processor This motherboard uses a socket AM2+/AM2 that carries the following features: • Accommodates AMD PhenomTM processor (socket AM2+) AMD AthlonTM 64X2 Dual-Core/AthlonTM 64/Sempron™ processors Supports HyperTransportTM (HT) 3.0 interface speeds • HyperTransportTM Technology is a point-to-point link between two devices, it enables integrated circuits to exchange information at much higher speeds than currently available interconnect technologies. Chipset The AMD RS780 Northbridge (NB) and SB700 Southbridge (SB) chipsets are based on an innovative and scalable architecture with proven reliability and perfor- mance. RS780 (NB) • One x4 A-Link Express II interface (PCI Express 1.1 compliant) for connection to an AMD Southbridge Supports one PCI Express x16 for Graphics Interface, fully compliant to the PCI Express Generation 2.0 (ver- sion 2.0) Proven RadeonTM graphics powering DirectX®10 Enhanced Digital Display integration Fully ACPI 2.0, OnNow, and IAPC (Instantly Available PC) power management Single chip solution in 55nm, 1.1 V CMOS technology Integrated ATI Hybrid Graphics® (support Hybrid CrossFireTM), ATI AvivoTM HD1, ATI PowerPlayTM, Low Power Design, AMD Cool’n’QuietTM 2.0, ATI SurroundViewTM, AMD OverDrive and AMD RAIDXpertTM Compliant with PCI v2.3 specification at 33 MHz Supports six Serial ATA devices which speeds up to 3.0 Gb/s Integrated USB 2.0 Host Controller supporting up to twelve USB 2.0 ports Integrated IDE controller supports Ultra ATA 133/100/66/ 33 modes • • • • • • • • • • SB700 (SB) Memory • Supports DDR2 1066 (AM2+)/800/667/533/400 DDR2 SDRAM with Dual- channel architecture Accommodates two unbuffered DIMMs Up to 8 GB per DIMM with maximum memory size up to 16 GB* • • Onboard LAN (optional) The onboard LAN controller provides either of the following features: • • • • • • Integrated 10/100/1000 Base-T Transceiver Integrated 10/100/1000 Mbps IEEE 802.3 compliant IEEE 802.3u Auto-Negotiation Integrated 10BASE-T/100BASE-TX Transceiver Integrated IEEE802.3z compliant IEEE 802.3u Auto-Negotiation Introducing the Motherboard
