NETWORKING

Native Gigabit Ethernet technology

  • The fastest Gigabit Ethernet solution in the market
  • Supports 10/100/1000Base-T Ethernet

Advanced networking features

  • TCP segmentation offloads
  • Jumbo frames
  • Checksum offloads
  • Interrupt moderation
  • Traffic prioritization
  • Remote wake-up
  • Network management for easy set up, configuration, and monitoring
TCP/IP Acceleration
  • Dedicated hardware engine
  • Reduces CPU overhead

STORAGE

NVIDIA RAID

  • RAID 0 disk striping support for highest system and application performance
  • RAID 1 disk mirroring support for fault tolerance
  • RAID 0 +1 disk striping and mirroring support for highest performance with fault tolerance
  • Disk alert system provides a visual indication so users know exactly which hard drive to replace during an array failure
  • Morphing allow users to change the current state of an array to another using one single step without reboot of the PC
  • Cross-controller RAID uniquely supports both SATA and PATA disk devices within a single array

Serial ATA

  • Support for SATA 3Gb/s, 1.5Gb/s disk controller standards
  • Dual controller architecture providing full 3Gb/s bandwidth to each disk
  • Features 4 integrated SATA 3Gb/s ports  

Fast Ultra ATA-133 Disk Drive Controller

  • 5V-tolerant primary and secondary channels, with support for up to four devices
  • Supports UltraDMA modes 6-0 (UltraDMA 33/66/100/133)
  • Industry-standard PCI bus master IDE register set
  • Separate independent IDE connections for 5V-tolerant primary and secondary interfaces

CONNECTIVITY

PCI Express interface

  • PCI Express high-performance, scalable interconnect. Rapidly being adopted by the PC industry; designed to replace the AGP and PCI interconnects currently in use.
  • x16 PCI Express link has 4 times the total bandwidth of today’s AGP 8X interface
  • x16 PCI Express link for high-performance graphics cards featuring the latest graphics processors with Microsoft DirectX 9 Shader Model 3.0 support
  • Additional x1 PCI Express links for other add-in cards
  • VC1 support on all links provide guaranteed bandwidth to CPU for time-sensitive applications

USB 2.0

  • USB 2.0 Enhanced Host Controller Interface (EHCI)/dual and USB 1.1 Open Host Controller Interface (OHCI)
  • Support for up to 10 ports
  • Supports transfer rates at high speed (480 Mbps), full speed (12 Mbps), and low speed (1.2 Mbps)
  • Dynamically configures slower devices for best utilization of bandwidth
  • Allows USB concurrency

PCI interface

  • Integrates a fast PCI-to-PCI bridge running at 33 MHz. Includes an arbiter that supports six external master PCI slots.
  • Features of the PCI interface include:
    • PCI 2.3-compliant, 5 V tolerant
    • Supports six external PCI slots at 33 MHz
    • Supports six bus master arbitration PCI master and slave interfaces
    • Supports both master-initiated and slave-initiated terminations
    • Bidirectional write posting support for concurrency
    • Flexible routing of all four PCI interrupts
    • Supports read ahead: memory read line (MRL) and memory read multiple (MRM)

PERFORMANCE

HyperTransport technology

  • 16 x 16 link running at 1GHz for extremely high throughput (8.0GB/sec)
  • Differential lines with low voltage swings

AUDIO

AC ’97 2.3 compliant interface

  • Supports 2, 4, 6, or 8-channel audio
  • Dual AC-Link: supports up to two codecs
  • Dual S/PDIF: supports two simultaneous digital outputs; handles stereo PCM or AC-3 output
  • 16-bit or 20-bit stereo, 48kHz output and 16-bit input streams across AC-Link
  • 24-bit, 96kHz stereo output on the secondary S/PDIF output
  • Supports input, output, and general purpose input/output (GPIO) channels for host-based modems
  • Separate independent functions for audio and modem

MOBILITY

  • Power management
  • Full support for AMD PowerNow! technology
  • ACPI 2.0 compliant
  • Support for ACPI C3 state
  • Low-power 0.15 micron process
  • Maximizing real estate efficiency enabling small form factor designs
    • Single-chip solution
    • Lower latency for higher performance
