Introducing the Motherboard
Feature
• Accommodates Intel P4/Celeron processors
• Supports a system bus (FSB) of 800/533MHz
• Supports “Hyper-Threading” technology CPU
The PT880Pro Northbridge (NB) and VT8237 Southbridge (SB) chipset is based on an
innovative and scalable architecture with proven reliability and performance.
PT880Pro
(NB)
• High performance Northbridge with 800MHz FSB for P4/
Celeron processors plus PCI Express and AGP bus
• Ultra V-link 1066 MB/sec high bandwidth North/South Bridge
interconnect
• Supports for AGP 8X/4X, AGP v3.0 compliant
• Supports one PCI Express Lite slot for Graphics Interface
• Advanced high-performance 128-bit, Dual-Channel, DDR
SDRAM controller
“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.
PT880PRO-A uses an LGA775 type of Pentium 4 that carries the following features:
Processor
Chipset
• Supports DDR 400/333/266 MHz or DDR2 533/400 DDR SDRAM DIMMs
• Accommodates four unbuffered DIMMs
• Up to 1 GB per DIMM with maximum memory size up to 2 GB
Memory
PT880Pro chipset can only support mixed 2048/1024/512/256/
128/64Mb x8/16 DDR2 SDRAMs or mixed 1024/512/256/128/
64Mb x8/16 DDR SDRAMs.
Users please note that DDR & DDR2 can’t both be applied at the same time on
this motherboard. Users can use either DDR or DDR2 memory modules only!
VT8237(SB)
• Supports 16-bit 66 MHz V-Link Host interface with total
bandwidth of 1066 MB/s
• Compliant with PCI 2.2 specification at 33 MHz, supporting
up to 6 PCI masters
• Integrated Serial ATA Host Controllers, supporting data trans-
fer rates up to 1.5Gb/s
• Integrated Dual channel UltraDMA 133/100/66 Master Mode
EIDE Controller
• USB 2.0 Controller, supporting up to 8 USB 2.0 ports
• Network Controller, supporting enterprise class 100/10 Mb
Fast Ethernet MAC
• Integrated keyboard Controller with PS2 mouse support
