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

Phenom

processor (socket AM2+)/Athlon

64 X2 Dual-Core/Athlon

64/

Sempron

processors for high-end business or personal desktop markets.

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.

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.

The motherboard incorporates the AMD RS780 Northbridge (NB) and AMD SB700

Southbridge (SB) chipsets. The Northbridge supports the HyperTransport

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.

*Due to the DRAM maximum size (2 GB per dimm) at present, the memory

maximum size we have tested is 4 GB.
