Introducing the Motherboard
Feature
• Accommodates Intel Pentium 4/Pentium D processors
• Supports a system bus (FSB) of 1066/800/533MHz
• Supports “Hyper-Threading” technology CPU
The 945P Northbridge (NB) and ICH7 Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
945P (NB)
• Supports 32-bit host bus addressing, allowing the CPU to
access the entire 4 GB of the memory address space.
• 2 GB/s point-to-point Direct Media Interface (DMI) to ICH7 (1
GB/s)each direction.
• Supports one PCI Express x16 for Graphics Interface, fully
compliant to the PCI Express Base Specification revision
1.0a.
• Supports 256-Mb, 512-Mb and 1-Gb DDR2 technologies for
x8 and x16 devices
• Supports up to four unbuffered DIMM
“Hyper-Threading” technology enables the operating system into thinking it’s hooked
up to two processors, allowing two threads to be run in parallel, both on separate
“logical” processors within the same physical processor.
The 945P-A uses an LGA775 type of Pentium 4/Pentium D that carries the following
features:
