Introducing the Motherboard
Feature
• Accommodates Intel P4 Prescott processors
• Supports a system bus (FSB) of 800/533MHz
• Supports “Hyper-Threading” technology CPU
The 915-P Northbridge (NB) and ICH6 Southbridge (SB) chipset is based on an innova-
tive and scalable architecture with proven reliability and performance.
915P (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 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 915P-A uses an LGA775 type of Pentium 4 that carries the following features:

• 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 LAN controller
• Compliant with Azalia specification supporting 8 Channels
of audio outputs
• Integrated IDE controller supports Ultra ATA100/66/33
• Supports DDR 400/333 MHz or DDR2 533/400 DDR SDRAM DIMMs
• Accommodates four unbuffered DIMMs
• Up to 1 GB per DIMM with maximum memory size up to 2 GB

915P 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.
Users please note that DDR & DDR2 can’t both be applied at the same time on
this motherboard. Users can use either DDR or DDR2 memory modules only!
