Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the E7320 (Lindenhurst-
VS) chipset, the X6DVA-4G/X6DVA-EG motherboard provides the perfor-
mance and feature set required for dual processor-based servers, with
configuration options optimized for communications, presentation, storage,
computation or database applications. The Intel E7320 (Lindenhurst-VS)
chipset consists of the following components: the E7320 (Lindenhurst-VS)
Memory Controller Hub (MCH), the I/O Controller Hub (6300ESB ICH), and
THE PCI-X Hub (PXH).
The E7320 (Lindenhurst-VS) MCH supports single or dual Nocona proces-
sors with Front Side Bus speeds of up to 800 MHz(*Note). Its memory
controller provides direct connection to two channels of registered DDR266,
DDR333 with a marched system bus address and data bandwidths of up to
6.4GB/s. The E7320 (Lindenhurst-VS) also supports the new PCI Express
high speed serial I/O interface for superior I/O bandwidth. The MCH pro-
vides configurable x8 PCI Express interfaces which may alternatively be
configured as two independent x4 PCI Express interfaces. These interfaces
support connection of the MCH to a variety of other bridges that are com-
pliant with the PCI Express Interface Specification, Rev. 1.0a. The MCH
interfaces with the 6300ESB I/O Controller Hub (6300ESB ICH) via Hub
Interface. The PCI- Bus provides connection between a PCI Express inter-
face and two independent PCI bus interfaces that can be configured for
standard PCI 2.3 protocol, as well as the enhanced high-frequency PCI-X
protocol. The PXH can be configured to support for 32- or 64-bit PCI de-
vices running at 33 MHz, 66 MHz, 100 MHz, and 133 MHz.
6300ESB ICH System Features
In addition to providing the I/O subsystem with access to the rest of the
system, the 6300ESB I/O Controller Hub (6300ESB ICH) integrates many I/
O functions.
The 6300ESB integrates: 2-channel Ultra ATA/100 Bus Master IDE Control-
ler, two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/
Flash BIOS Interface, PCI-X (66MHz) 1.0 Interface, PCI 2.2 Interface and
System Management Controller.
(*Notes: The CPU FSB speed is set at 800 MHz by the Manufacturer.
Please do not change the CPU FSB setting.)
