AMD® Athlon™ / Athlon™ XP and Duron™ Socket A (462) Processor

North Bridge Chipset: the nVidia® 220D GeForce MX Integrated GPU/ North Bridge controller chipset. The controller supports a 64bit DDR memory controller and up to 1 GB of 266/200MHz DDR SDRAM memory. The 64bit memory controller provides a exceptional 2.1 GB/second system memory bandwidth.

South Bridge Chipset: Features the brand new nVidia® nForce™ MCP-D 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™ digital encoding. The controller supports standard UltraDMA/100/66/33 for burst mode data transfer rates of up to 100MB/sec. Separate data paths for each IDE channel are built-in for up to four IDE devices. The controller supports six USB ports and is PCI rev 2.2 compliant. The MCP supplies an LPC

1.0interface along with AT legacy functions, a clock synthesizer and meets ACPI 1.0 and PCI Power Management 1.1 specifications.

PC2100 / PC1600 DDR Support: Equipped with two Double Data Rate Dual Inline Memory Module (DDR DIMM) sockets to support up to 1GB of DDR DRAM, the newest memory standard with the highest bandwidth and lowest latency currently available. This new memory technology increases performance by executing two actions per clock cycle, resulting in data transfer rates of up to 2.1 GB/s for 133MHz DDR SDRAM and 1.6GB/s for 100MHz DDR SDRAM.

UltraDMA/100 Support: Comes with an onboard PCI Bus Master IDE controller with two connectors that support four IDE devices on two channels. Supports UltraDMA100/66/33, 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: Offers complete 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.

Connections: Parallel Port, PS/2 mouse Port, PS/2 keyboard, 2 USB ports, Microphone, Line In Jack, Line Out Jack, Standard ATX power.
