System Board
1.1
Features
The DX6G Plus is a dual-processor system board built on an
®
extended ATX baseboard utilizing two Pentium
II processors running
®
at 400/100 and 450/100 MHz or two Pentium
III processors running
at 500/100 and 550/100 MHz. It is integrated with the Intel 440GX
system controller, which consists of the PCI/AGP controller and the
PCI/ISA IDE accelerator (PIIX4E).
®
®
The Pentium
II and Pentium
III processor implements a Dynamic
Execution micro-architecture - a unique combination of multiple
branch prediction, data flow analysis, and speculative execution. This
means that it can deliver higher performance than the previous
®
Pentium
processor while maintaining binary compatibility with all
previous Intel Architecture processors.
®
The PCI/AGP controller host bus interface supports both Pentium
II
®
and Pentium
III with 100 MHz bus frequency. It also provides a 72-
bit DIMM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller introduces a new technology, which is the
Accelerated Graphics Port (AGP) interface.
Supporting up to
533MB/sec MHz data transfer rate, the AGP interface boosts graphics
performance.
The PIIX4E is a multifunctional PCI device controller implementing
system functions including PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
