1.3.1 Product highlights
Latest processor technology
The motherboard comes with two LGA-771 sockets that support Dual-Core and
Quad-Core Intel
®
Xeon™ processors with 1600/1333/1066 MHz Front Side Bus
(FSB). Dual-core processors contain two physical CPU cores to meet demands
for more powerful processing. Intel
®
Xeon™ processors incorporate the Intel
®
Extended Memory 64-bit Technology, enabling the support for 64-bit operation
system, such as 64-bit Windows
®
and Linux. See page 2-9 for details.
Intel
®
Seaburg and Intel
®
ESB2E chipset
The Intel
®
Seaburg Memory Controller Hub (MCH) and the Intel
®
ESB2E provide
the vital interfaces for the motherboard. The MCH provides two channels for
processor, quad-channel FB-DIMM memory support, and two PCI Express 2.0
interfaces. The Intel
®
ESB2E is a new generation server class I/O controller hub
that provides the interface for PCI 2.3, PCI Express, and PCIX.
Intel
®
EM64T
The motherboard supports Intel processors with the Intel
®
EM64T (Extended
Memory 64 Technology). The Intel
®
EM64T feature allows your computer to run on
64-bit operating systems and access larger amounts of system memory for faster
and more efcient computing.
Enhanced Intel SpeedStep
®
Technology (EIST)
The Enhanced Intel SpeedStep
®
Technology (EIST) intelligently manages the
CPU resources by automatically adjusting the CPU voltage and core frequency
depending on the CPU loading and system speed or power requirement.
FB-DIMM memory support
This motherboard supports fully buffered DIMMs (FB-DIMMs), the latest memory
solution that extends memory capacity and provide high-speed, high-density
system memory peformance. FB-DIMMs use Advanced Memory Buffer (AMB)
chips that transmit signals between the memory modules and controllers with
improved signal integrity and reduced errors. See page 2-14 for details.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices. See page 2-21 for details.
