Introducing the Motherboard
Feature
• Accommodates Intel Core
TM
2 Duo/Pentium D/Pentium 4/Celeron D proces-
sors
• Supports a system bus (FSB) of 1066/800/533 MHz
• Supports “Hyper-Threading” technology CPU
The 946GZ Northbridge (NB) and ICH7 Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
946GZ (NB)
“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.
Processor
