AMD Athlon / Athlon
North Bridge Chipset: the nVidia
chipset. The controller supports a 64/128bit DDR memory controller and
up to 3 GB of 400/333/266/200MHz DDR memory. The 128bit memory
controller provides a exceptional 6.4 GB/second system memory
bandwidth.
South Bridge Chipset: Features the brand new nVidia
MCP integrated peripheral South Bridge controller operates at 800MB/
sec to communicate with the North Bridge for maximum bandwith required
for PCI, USB and support for Fast Ethernet devices. The chipset has an
integrated APU (Audio Processing Unit) for Dolby
encoding(optional). The controller supports standard UltraDMA133/100/
66/33 for burst mode data transfer rates of up to 133MB/sec. Separate
data paths for each IDE channel are built-in for up to two IDE devices.
The controller supports 2 IEEE 1394 ports (optional), six USB ports, two
LAN ports (optional), and is PCI rev2.2 compliant. The MCP-T/MCP
supplies an LPC 1.0 interface along with AT legacy functions, a clock
synthesizer and meets ACPI 1.0 and PCI Power Management 1.1
specifications.
PC3200 / PC2700 DDR Support: Equipped with three Double Data Rate
Dual Inline Memory Module (DDR DIMM) sockets to support up to 3GB of
DDR DRAM, the newest memory standard with the highest bandwidth
and lowest latency currently available. This new memory technology
supplies data transfer rates up to 6.4 GB/s for 400MHz DDR SDRAM
and 5.4GB/s for 333MHz DDR SDRAM.
UltraDMA133/100 Support: Comes with an onboard PCI Bus Master IDE
controller with two connectors that support four IDE devices on two
channels. Supports UltraDMA133/100/66/33, PIO Modes 3 & 4, Bus
Master IDE DMA Mode 2, and Enhanced IDE devices, such as DVD-
ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
Multi-I/O Chipset: ITE IT8708 offers support for a variety of I/O functions.
Provides two high-speed UART compatible serial ports and one parallel
port with EPP and ECP capabilities. UART2 can also be directed from
COM2 to the Infrared Module for wireless connections. The Super I/O
controller supports a floppy disk drive, PS/2 keyboard, and PS/2 mouse.
