ASUS A7PRO User’s Manual
2.1 The ASUS A7PRO
The ASUS A7PRO motherboard is carefully designed for the value-conscious PC
user who wants advanced features processed by the fastest processors.
2.1.1 Specifications
• AMD Athlon™/Duron™ Processor Support: Supports Socket A-based AMD
Athlon™/Duron™ processors.
• North Bridge System Chipset: Features the VIA VT8363 (VIA Apollo KT133)
system controller with support for a 200MHz Front Side Bus (FSB); up to 1.5GB
of PC133/PC100 SDRAM / VC 133 Virtual Channel Memory (VCM) SDRAM;
complies with AGP 2.0 specifications for 4X, 2X, and 1X AGP modes; and PCI
2.2. bus interface with support for 5 PCI masters. It is optimized to deliver en-
hanced AMD Athlon™/Duron™ processor system performance.
• “Super South” South Bridge System PCIset: VIA VT82C686A PCIset with
PCI Super-I/O Integrated Peripheral Controller (PSIPC) with support for
UltraDMA/66, which allows burst mode data transfer rates of up to 66.6MB/sec;
AC97 audio; USB controller with root hub and four function ports.
• PC133 SDRAM / VC133 VCM Support: Equipped with three Dual Inline
Memory Module (DIMM) sockets to support Intel PC133/PC100-compliant (8,
16, 32, 64, 128, 256, or 512MB) or NEC’s VC133-compliant Virtual Channel
(VC) SDRAM up to 1.5GB. VC SDRAM is a new DRAM core architecture that
dramatically improves the memory system’s ability to service, among others, high
multimedia requirements.
• Stepless Frequency Selection: Allows CPU external (FSB) frequency settings
to be set in 1MHz-increments or reduction.
• JumperFree™ Mode: Adjust processor frequency settings and makes
overclocking and Vcore voltage control easy, all through BIOS setup. Easy-to-
use DIP switches instead of jumpers are included to allow manual adjustment of
the processor’s external frequency.
• AGP Pro Slot: Supports AGP/AGP Pro cards for high performance, component
level interconnection targeted at 3D graphical applications supporting 133MHz
4X mode.
• UltraDMA/66 Support: Comes with an onboard PCI Bus Master IDE control-
ler with two connectors that support four ATA66/33 devices on two channels.
Supports UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and 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.
• Wake-On-LAN Connector: Supports Wake-On-LAN activity through an op-
tional ASUS PCI-L101 10/100 Fast Ethernet PCI card (see 7. Appendix).
