Processor
The SVX400 mainboard includes a mPGA Socket 478 that has
the following features:
•
Supports up to a 400/533 MHz front side bus (FSB)
•
Accommodates Intel Pentium 4 processors
Chipset
The chipset on SVX400 includes the VT8754 Northbridge and
VT8235 Southbridge which are based on an innovative and
scalable architecture with proven reliability and performance. A
few of the chipset's advanced features are:
•
An advanced V-Link memory controller architecture that
provides the bandwidth and performance necessary for
even the most demanding Internet and 3D graphics
•
Support for an 2x/4x8xAGP interface providing vivid 3D
graphics and video performance
•
An ATA 133 interface on the VT8235 chipset, which helps
boost system performance by providing a high-speed
connection to ATA 133 Hard Disk Drives, delivering
maximum sustained data transfer rates of 133 MB/sec
Additional features include support for four USB ports, an AC
97 link for audio and modem, hardware monitoring, and
ACPI/OnNow power management.
Memory
The mainboard accommodates three 184 pin, 2.5V DDR
DIMM sockets with a total capacity of 12 GB.
VGA
The SVX400 includes an 8xAGP slot that provides eight times
the bandwidth of the original AGP specification. The AGP 3.0
(8xAGP) offers a significant increase in performance along
with feature enhancements to AGP2.0. This interface
represents the natural evolution from the existing AGP to meet
the ever-increasing demands placed on the graphic interfaces
within the workstation and desktop environments.
AC' 97 Audio
The AC'97 Audio codec is compliant with the AC' 97 2.2
Codec
specification, and supports 18-bit ADC (Analog Digital
Converter) and DAC (Digital Analog Converter) resolution as
well as 18-bit stereo full-duplex codec with independent and
variable sampling rates. Further features include support for
four analog line-level stereo inputs.
USB 2.0
The built-in VIA VT8235 PCI 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
th
1/8
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
support 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
•
PCI multi-function device consists of two UHCI Host
Controllers for full/low-speed signaling and one EHCI Host
