Introducing the Motherboard
Features
Processor
This motherboard uses a mPGA 478-pin socket that carries the following features:
• Accommodates Intel P4 Willamette/Northwood/Prescott 478-pin CPU
• Supports a system bus (FSB) of 800*(overclocking)/533/400 MHz
(*A CPU with 800MHz FSB requires using DDR400)
Intel’s 845PE(MCH) Northbridge (NB) and 82801DB(ICH4) Southbridge (SB) chipsets
are based on an innovative and scalable architecture with proven reliability and perfor-
mance.
845PE(NB)
