Processor
The P4ITM mainboard uses a PGA Socket 423
that has the following features:
Accommodates Intel Pentium 4 CPUs
Supports a frontside bus (FSB) of 400 MHz
Supports 3.2 GB/s data bus bandwidth
Chipset
Intel’s innovative Tehama 850 Northbridge and
82801 Southbridge chipsets are based on an in-
novative and scalable architecture with proven
reliability and performance. A few of the advanced
features of the chipsets are:
•
Host interface controller supports 400 MHz
frontside (system) bus frequency
•
Supports up to 2 GB of Rambus DRAM
•
Supports a maximum memory bandwidth of
3.2 GB/s
•
AGP controller is AGP 2.0 compliant and sup-
ports 2x/4x Fast Write Protocol (1.5V only)
•
PCI IDE controller supports PCI bus master-
ing, PIO modes 0~4, and UDMA 33/66/100
•
Two USB controllers double the bandwidth to
24 Mbps across four ports
•
Integrated AC 97 audio that supports full sur-
round sound with up to six channels
Additional key features include support for four USB
ports, an AC 97 link for audio and modem, hardware
monitoring, and ACPI/OnNow power management.
Memory
The mainboard accommodates Rambus DRAM
up to 2 GB using 2.5V unbuffered Rambus DRAM
(RDRAM) memory modules.
VGA
The P4ITM includes a 4xAGP slot that provides four
times the bandwidth of the original AGP specifica-
tion. AGP technology provides a direct connection
between the graphics sub-system and the processor
so that the graphics do not have to compete for
processor time with other devices on the PCI bus.
AC 97 Audio
Codec
The AC 97 Audio codec is compliant with the AC
