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)
•
Supports DDR400 (overclocking)/333/266 unbuffered non-ECC DDR
DIMMs
• Supports a single processor with a Data Transfer-Rate of 800
(overclocking, requires using DDR400)/533/400MHz
• AGTL+Host Bus With Integrated Termination supporting 32-bit Host
Addressing
• Supports 3D Setup and Render Engine and zone rendering with high
quality texture engine.
Chipset
This motherboard can accommodate two 2.5V DIMM DDR SDRAM, supporting DDR400
(overclocking)/333/266 with maximum memory size of 2GB capability.
The AC’97 Audio CODEC is compliant with the AC’97 2.3 specification that meets the
PC2001 requirements. It also has a built-in buffer and internal PLL. Features include
support for analog switch for rear-out (share), the line-in jack (share), center/bass (share),
and MIC jack to output 6 channels audio.
