1-2 Chip Set Overview
The 440GX chip set, developed by Intel, is the ultimate processor platform tar-
geted for 3D graphics and multimedia applications. Along with a System-to-PCI
bridge integrated with an optimized DRAM controller and data path, this chip set
supports the Accelerated Graphics Port (AGP) interface. AGP is a high perfor-
mance, component level interconnect targeted at 3D applications and based on
a set of performance enhancements to PCI. The I/O subsystem portion of the
440GX platform is based on the PIIX4, a highly integrated version of Intel's PCI-
to-ISA bridge family.
The PCI/AGP and system bus interface controller (82443GX) supports up to two
Pentium II/III processors. It provides an optimized 72-bit DRAM interface (64-bit
data plus ECC). This interface supports 3.3V DRAM technologies. The control-
ler 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 inter-
face is based on AGP Specification Rev 1.0. It can support data transfer rates
of up to 133 MHz (532 MB/s) .
1-3 Slot 2 Architecture
The Slot 2 architecture supports Intel Pentium II and III Xeon CPUs. This tech-
nology offers a larger L2 cache that can run at full CPU speed.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER S2DG2/
S2DGU/S2DGE/S2DGR. 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 continu-
ously. 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.
