Processor Support
• North Bridge System Chipset: Features the VIA
®
KT266A North Bridge that
supports AGP 4X/2X mode, 133/100MHz Front Side Bus (FSB), and
266/200MHz memory bus.
• South Bridge System Chipset: VIA
®
VT8233A integrated peripheral controller
supports UltraDMA133/100/66/33 for burst mode data transfer rates of up to
133MB/sec, and USB controller with two root hubs for four USB ports.
• PC2100 / PC1600 DDR Support: Equipped with three Double Data Rate Dual
Inline Memory Module (DDR DIMM) sockets to support up to 3GB of DDR
DRAM. DDR DRAM is the newest memory standard with the highest bandwidth
and lowest latency currently available. DDR dramatically improves the memory
system’s ability to service, among others, high multimedia requirements. (Caution:
Do not attempt to use SDRAM modules.)
• JumperFree™ Mode: Make processor settings to overclock frequency and
Vcore voltage through BIOS. Easy-to-use DIP switches come with the
motherboard board for manual adjustment of processor frequencies.
• UltraDMA/133 Support: Comes with an onboard PCI Bus Master IDE controller
with two connectors that support four IDE devices on two channels. Supports
UltraDMA133/100/66/33, PIO Modes 3 & 4, Bus Master IDE DMA Mode 2,
and Enhanced IDE devices:DVDs, CD-R/RW, LS-120, and Tape Backup drives.
• Super Multi-I/O: The 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
also supports a floppy disk drive, PS/2 keyboard, and PS/2 mouse.
• Optional Promise
®
chip: The Promise IDE controller chip supports the ATA-
133 protocol and Ultra DMA/133 data transfer speeds. The chip also delivers
reliable redundancy and stable performance for RAID levels 0 or 1. Data
“striping,” RAID 0, improves speed performance as I/O tasks are spread between
two hard disk drives. Data “mirroring,” RAID 1, improves system fault tolerance
by optimizing two identical hard disks to write data to each other.
• C.O.P. Thermal Protection: With AMD
®
Athlon XP
™
installed, the motherboard
offers users ASUS C.O.P. automatic CPU Overheating Protection to prolong the
life of the entire system. If the CPU temperature becomes excessive, the PC
shuts down automatically.
