Introducing the Motherboard
Feature
• Accommodates Intel P4 Prescott processors
• Supports a system bus (FSB) of 800/533MHz
• Supports “Hyper-Threading” technology CPU
The 915G Northbridge (NB) and ICH6 Southbridge (SB) chipset are based on an inno-
vative and scalable architecture with proven reliability and performance.
915G (NB)
• Supports 32-bit host bus addressing, allowing the CPU to
access the entire 4 GB of the memory address space
• Has a 12-deep In-Order Queue to support up to twelve
outstanding piplined address requests on the host bus
• 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 DDR technologies for
x8 and x16 devices
• Supports DDR 333/400 MHz up to four unbuffered DIMM
with 4 GB maximum memory size
• Provides an integrated graphics device delivering cost com-
petitive 3D, 2D and video capabilities.
“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 915G-M uses a LGA775 type of Pentium 4 that carries the following features:
ICH6(SB)
Processor
Chipset
• Enhanced DMA Controller, interrupt controller, and timer func-
tions
• Compliant with PCI Express Base Specification, Revision
1.0a
• Compliant with PCI 2.3 specificaiton
• Compliant with Serial ATA 1.0a specification
• Integrated USB 2.0 Host Controller supporting up to eight
USB 2.0 ports
• Integrated IDE controller supports Ultra ATA100/66/33
915G chipset can only support 256-Mb, 512-Mb and 1-Gb DDR technologies
for x8 and x16 device, NOT support 128-Mb DDR technology. That is, 256
MB Double Side Memory Module & 128 MB Single Side Memory Module are
NOT support.
• Supports DDR 400/333 MHz DDR SDRAM DIMMs
• Accommodates four unbuffered DIMMs
• Up to 1 GB per DIMM with maximum memory size up to 4 GB
