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 line-out.
*Due to the DRAM maximum size (2 GB per dimm) at present, the memory
maximum size we have tested is 4 GB.
The motherboard incorporates the AMD 785G Northbridge (NB) and SB710
Southbridge (SB) chipsets. The Northbridge supports the HyperTransport
TM
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, are fully
compliant to the PCI Express Gen2 (version 2.0). In addition, one PCI Express x1
slot is supported.
The SB710 Southbridge supports two PCI slots which are PCI v2.3 compliant. It
integrates USB 2.0 interface, supporting up to eight functional ports (four USB ports
and two USB 2.0 headers support additional four USB ports). One onboard IDE
connector supports two IDE devices in Ultra ATA 133/100/66/33 modes. The
Southbridge integrates a Serial ATA host controller, supporting six SATA ports with
maximum transfer rate up to 3.0 Gb/s each. It provides AMD SATA RAID configura-
tion with RAID 0, 1 and 10 modes supported.
