Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the E7525 Tumwater
chipset, the X6DAL-XTG motherboard provides the performance and fea-
ture set required for dual processor-based servers, with configuration op-
tions optimized for communications, presentation, storage, computation or
database applications. The Intel E7525 Tumwater chipset consists of the
following components: the E7525 Tumwater Memory Controller Hub (MCH),
the Hance Rapids I/O Controller Hub (Hance Rapids ICH), the Intel PCI-X
Hub, and PCI-X Hub (PXH).
The E7525 Tumwater MCH supports single or dual Nocona processors with
Front Side Bus speeds of up to 800 MHz(*Note). Its memory controller pro-
vides direct connection to two channels of registered DDR333 or DDR266
with a marched system bus address and data bandwidths of up to 2.67 GB/
s (DDR 333) per channel. The E7525 Tumwater also supports the new PCI
Express high speed serial I/O interface for superior I/O bandwidth. These
interfaces support connection of the MCH to a variety of other bridges that
are compliant with the PCI Express Interface Specification, Rev. 1.0a. The
MCH interfaces with the Hance Rapids ICH I/O Controller Hub via HI 1.5 Hub
Interface. The PXH provides connection between a PCI Express interface
and two independent PCI bus interfaces that can be configured for stan-
dard PCI 2.3 protocol, as well as the enhanced high-frequency PCI-X proto-
col. The PXH can be configured to support for 32- or 64-bit PCI devices
running at 33 MHz, 66 MHz, 100 MHz, or 133 MHz.
Hance Rapids ICH System Features
In addition to providing the I/O subsystem with access to the rest of the
system, the Hance Rapids ICH I/O Controller Hub integrates many I/O
functions.
The Hance Rapids ICH I/O Controller Hub integrates: 2-channel Ultra ATA/
100 Bus Master IDE Controller, two Serial ATA (SATA) Host Controllers,
SMBus 2.0 Controller, LPC/Flash BIOS Interface, PCI-X (66MHz)/PCI-Express
(x16 at 4GB/s) Interface, PCI 2.2 Interface and System Management Con-
troller.
(*Notes: The CPU FSB speed is set at 800 MHz by the Manufacturer.
Please do not change the CPU FSB setting.)
