1-2 Chipset Overview
Built upon the functionality and the capability of the 5000X (Greencreek) chipset,
the X7DA3+ motherboard provides the performance and feature set required for
dual processor-based workstations with confi guration options optimized for com-
munications, presentation, storage, computation or database applications. The
5000X (Greencreek) chipset supports single or dual Xeon 64-bit dual core processor
with front side bus speeds of up to 1.333 GHz. The chipset consists of the 5000X
(Greencreek) Memory Controller Hub (MCH), the Enterprise South Bridge 2 (ESB2),
and the I/O subsystem (PXH-V).
The 5000X (Greencreek) MCH chipset is designed for symmetric multiprocessing
across two independent front side bus interfaces. Each front side bus uses a 64-bit
wide, 1.333 GHz data bus that transfers data at 10.7 GB/sec. The MCH chipset con-
nects up to 8 Fully Buffered DIMM modules, providing a total of 32.0 GB/s for DDR2
667/533 memory. The MCH chipset also provides one x8 PCI-Express and one x4
ESI interface to the ESB2. In addition, the 5000X (Greencreek) 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.
