2.1.1 Core Specifications
• AMD
®
Athlon
™
XP / Athlon
™
/ Duron
™
Processor support: Features the latest
AMDs, 500MHz to 1.6 GHz and higher.
• North Bridge System Chipset: Features the brand new nVidia
®
nForce
™
IGP-
128 integrated GPU/North Bridge controller chipset. The controller supports a
64/128bit DDR memory controller integrated with a GeForce2 MX-class
advanced Graphics Processing Unit (GPU) with a high performance dual pixel
processing pipeline, a 256-bit 3D/2D graphics accelerator that supplies per pixel
shading rasterization and a full AGP 4X interface, a digital video interface to
DVI transmitters /TV encoders and an interface for up to 1.5 GB of 266/200MHz
DDR SDRAM memory. The 128bit memory controller provides a phenomenal
4.2 GB/second system memory bandwidth.
• South Bridge System 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) that provides 6-Channel AC’97 compliant 3D positional
audio and 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 to support up to four IDE devices. The
controller supports six USB ports and 5 PCI slots and is PCI rev 2.2 compliant.
The 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.
• PC2100 / PC1600 DDR Support: Equipped with three Double Data Rate Dual
Inline Memory Module (DDR DIMM) sockets to support up to 1.5GB of DDR
DRAM. DDR DRAM supplies the highest bandwidth (64/128 bit) and offers
the lowest latency currently available, improving the memory system’s ability to
service multimedia requirements.
• Easy Frequency Changes: Now, easily overclock all important frequency
settings - simply and quickly with the onboard BIOS firmware.
• Smart BIOS: 2Mb firmware enables Vcore and CPU/DDR SDRAM frequency
adjustments, boot-block write protection, enhanced ACPI, DMI, Green and PnP
Features Plus.
