1-2 Chipset Overview
The 440BX chipset, developed by Intel, is the ultimate processor platform
targeted for 3D graphics and multimedia applications. Along with a System-
to-PCI bridge integrated with an optimized DRAM controller and data path,
this chipset supports the Accelerated Graphics Port (AGP) interface. AGP
is a high performance, component level interconnect targeted at 3D applica-
tions and based on a set of performance enhancements to PCI. The I/O
subsystem portion of the 440BX platform is based on the PIIX4E, a highly
integrated version of Intel's PCI-to-ISA bridge family.
The PCI/AGP and system bus interface controller (82443BX) supports up to
two Pentium II/III processors. It provides an optimized 72-bit DRAM interface
(64-bit data plus ECC) that supports 3.3V DRAM technology. The controller
provides the interface to a PCI bus operating at 33 MHz. This interface
implementation is compliant with the PCI Rev 2.1 Specification. The AGP
interface is based on AGP Specification Rev 1.0. It can support data trans-
fer rates of up to 133 MHz (532 MB/s).
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P6DBU/P6DBS/P6DBE/P6SBU/P6SBS/P6SBA/P6SBM. All have an onboard
System Hardware Monitor chip that supports PC health monitoring.
Seven Onboard Voltage Monitors for the CPU Core(s),
CPU I/O, +3.3V,
±±
±±
±5V,
and
±±
±±
±12V
The onboard voltage monitor will scan these seven monitored voltages con-
tinuously. Once a voltage becomes unstable, it will give a warning or send
an error message to the screen. Users can adjust the voltage thresholds
to define the sensitivity of the voltage monitor.
