Motherboard Features

At the heart of the SuperWorkstation 7043A-8R/7043A-i lies the X5DA8/X5DAE,
a dual processor motherboard designed to provide maximum performance. Below
are the main features of the X5DA8/X5DAE.
Chipset Overview
The X5DA8/X5DAE is based on Intel's E7505 chipset. See Figure 1-1 for a block
diagram of the chipset. he E7505 chipset consists of three major components:
the Memory Controller Hub (MCH), the I/O Controller Hub 4 (ICH4) and the PCI-
X 64-bit Hub 2.0 (P64H2).
Memory Controller Hub (MCH)
The MCH has four hub interfaces, one to communicate with the ICH4 and three
for high-speed I/O communications. The MCH employs a 144-bit wide memory
bus for a DDR-266 memory interface, which provides a total bandwidth of 4.27
GB/s. The ICH4 interface is a 266 MB/sec point-to-point connection using an 8-
bit wide, 66 MHz base clock at a 4x data transfer rate. The P64H2 interface is
a 1 GB/s point-to-point connection using a 16-bit wide, 66 MHz base clock at an
8x data transfer rate.
I/O Controller Hub (ICH4)
The ICH4 I/O Controller Hub provides various integrated functions, including a
two-channel Ultra ATA/100 bus master IDE controller, USB 2.0 host controllers,
an integrated LAN controller, a System Management Bus controller and an AC'97
compliant interface.
