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 TV 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
integrated peripheral South Bridge controller operates at 800MB/sec to
communicate with the North Bridge for maximum bandwith required for PCI,
USB, AC’97 Audio/Modem and Fast Ethernet devices. 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 MCH 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 through onboard BIOS firmware.
• Smart BIOS: 2Mb firmware enables Vcore and CPU/DDR SDRAM frequency
adjustments, boot block write protection, and enhanced ACPI, DMI, Green, PnP
Features Plus.
