Introducing the Motherboard
Feature
• Accommodates Intel P4/Celeron processors
• Supports a system bus (FSB) of 800/533MHz
• Supports “Hyper-Threading” technology CPU
The 915PL Northbridge (NB) and ICH6 Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
“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 915PL-A2 uses an LGA775 type of Pentium 4 that carries the following features:
Processor
Chipset
915PL (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 Sepcification revision
