Processor
The motherboard uses a micro PGA 478-pin socket that has
the following features:
•
Supports 533/400 MHz frontside bus (FSB)
•
Accommodates Pentium 4 processors at 1.5G/1.6G/1.7G
…3.06G and above
Chipset
The
SiS651 Northbridge
and
SiS962L
Southbridge chipsets
are based on an innovative and scalable architecture with
proven reliability and performance.
•
Support Intel Pentium 4 series CPU with data transfer
rate of 533/400MHz
•
Support 12 outstanding transactions
•
Supports DDR333/266/200 SDRAM
•
AGP v2.0 Compliant
•
Supports Graphic Window Size from 4MBytes to
256Mbytes
•
Perform 533MB/s bandwidth in 66MHz x 4 mode
•
Built-in a high quality 3D engine
•
PCI 2.2 specification compliance
•
Supports PIO mode 0,1,2,3,4 and Multiword DMA mode
0,1,2
•
Supports Ultra DMA 133/100/66
•
Three independent OHCI USB 1.1 host controllers and
one EHCI USB 2.0 host controller, support up to six ports
•
System wake-up events include: Power button, keyboard
password/hot key, RTC alarm, Modem ring-in, LAN,
AC’97 wake-up, USB wake up and 1394 wake up
Additional key features of the motherboard include support for
six USB ports, an AC’ 97 link for audio and modem, hardware
monitoring, and ACPI/OnNow power management.
Memory
The motherboard supports DDR 333/266 SDRAM. It accom-
modates two unbuffered 2.5V 184-pin slots. Each slot supports
up to 1 GB with a total maximum capacity of 2 GB.
Graphics
The motherboard includes an AGP slot that provides four
times the bandwidth of the original AGP specification. AGP
technology provides a direct connection between the graphics
sub-system and the processor so that the graphics do not
have to compete for processor time with other devices on the
PCI bus.
USB
The USB 2.0 Controller is compliant with Universal Serial Bus
Specification Revision 2.0.
The USB 2.0 supports data transfer rates up to 480MB/sec for
high-speed devices and specifies a microframe that will be
1/8
th
of a 1msec frame. This allows the USB 2.0 devices to
have small buffers even at high data rates.
The USB 1.1 connectors and other full speed cables can sup-
port the higher speed of USB 2.0 without any changes.
The chipset has the following advanced USB features:
•
Compliant with Enhanced Host Controller Interface
(EHCI) Specification Revision 0.95 and Universal Host
Controller Interface (UHCI) Specification Revision 1.1
