Introducing the Motherboard
Feature
• Accommodates Intel Core
TM
2 Duo/Pentium D/Pentium 4/Celeron D
processors
• Supports a system bus (FSB) of 1066/800/533 MHz
• Supports “Hyper-Threading” technology CPU
The motherboard uses an LGA775 type of Intel Core
TM
2 Duo/Pentium D/
Pentium 4/Celeron D that carries the following features:
Processor
The 945GC Northbridge (NB) and ICH7 Southbridge (SB) chipsets are based on
an innovative and scalable architecture with proven reliability and performance.
Chipset
ICH7 (SB)
• Enhanced DMA Controller, interrupt controller, and
timer functions
• Compliant with PCI Express Base Specification, Re-
vision 1.0a
• Compliant with PCI 2.3 specification
• Integrated SATA 3.0 Gb/s Host Controller
• Integrated USB 2.0 Host Controller supporting up to
eight USB 2.0 ports
• Integrated IDE controller supports Ultra ATA 100/66/
33
• Supports DDR2 667/533/400 DDR SDRAM with Dual-channel archi-
tecture
• Accommodates two unbuffered DIMMs
• Up to 1 GB per DIMM with maximum memory size up to 2 GB
Memory
945GC (NB)
• Supports 32-bit host bus addressing, allowing the
CPU to access the entire 2 GB of the memory ad-
dress 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 Inter-
face, fully compliant to the PCI Express Base Speci-
fication revision 1.0a.
• Supports 256-Mb, 512-Mb and 1-Gb DDR2 technolo-
gies for x8 and x16 devices
• Supports high quality 3D setup, Render Engine and
high-quality texture engine
“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.
Audio
• 5.1 channel High Definition Audio Codec
• All DACs Support 192K/96K/48K/44.1KHz DAC sample rate
• Software selectable 2.5V/3.75V VREFOUT
• Meets Microsoft WHQL/WLP 2.x audio requirements
• Direct Sound 3D
