1.4.1 Product highlights
Latest processor technology
The motherboard comes with two LGA-771 sockets that support Dual-Core and
Quad-Core Intel
®
Xeon™ processors with 1333/1066/667 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
®
Hyper-Threading Technology and Extended Memory 64-bit Technology (EM64T).
The EM64T enables the support for 64-bit operation system, such as 64-bit
Windows
®
and Linux. See page 2-11 for details.
Intel
®
5000V
and Intel
®
6321ESB chipset
The Intel
®
5000V
Memory Controller Hub (MCH) and the Intel
®
6321ESB provide
the vital interfaces for the motherboard.
The MCH provides the processor, dual-channel FB-DIMM memory support, and
PCI Express interfaces. The Intel
®
6321ESB 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 2-16 for details.
