1-2 Chipset Overview
A. The Intel 5000P Chipset (*for the X7DBT/X7DBT-INF)
Built upon the functionality and the capability of the 5000P chipset, the X7DBT/
X7DBT-INF motherboard provides the performance and feature set required for dual
processor-based servers with confi guration options optimized for communications,
presentation, storage, computation or database applications. The 5000P chipset
supports single or dual Xeon 64-bit dual core processor(s) with front side bus
speeds of up to 1.333 GHz. The chipset consists of the 5000P Memory Controller
Hub (MCH) and the Enterprise South Bridge 2 (ESB2).
The 5000P MCH chipset is designed for symmetric multiprocessing across two
independent front side bus interfaces. Each front side bus uses a 64-bit wide, 1333
MHz data bus that transfers data at 10.7 GB/sec. The MCH chipset connects up
to eight Fully Buffered DIMM modules, providing a total memory of up to 32.0 GB
for DDR2 667/533 MHz. The MCH chipset also provides one x8 PCI-Express and
one x4 ESI interfaces to the ESB2. In addition, the 5000P chipset offers a wide
range of RAS features, including memory interface ECC, x4/x8 Single Device Data
Correction, CRC, parity protection, memory mirroring and memory sparing.
The Xeon Dual Core Processor Features
Designed to be used with conjunction of the 5000P chipset, the Xeon dual core
Processor provides a feature set as follows:
The Xeon Dual Core Processors
*L1 Cache Size: Instruction Cache (32KB/16KB), Data Cache (32KB/24KB)
*L2 Cache Size: 4MB/2MB (per core)
*Data Bus Transfer Rate: 8.5 GB/s
*Package: FC-LGA6/FC-LGA4, 771 Lands
