Introduction of PT800DB/PT800DBP/PT800DBZ Motherboard

Thank you for purchasing the PT800 series which provide extremely
performance and meet future specification demand.
PT800 series motherboards are adopted with advanced technologies to deliver the
extremely performance for Intel Pentium 4 socket 478 processors. PT800 series
motherboards also feature AGP 8X, Serial ATA RAID0, 1, USB 2.0 as well as 6-channel
audio which are based on the advanced VIA PT800 chipset with FSB 800MHz and DDR
400 MHz support. Now we could know more details by reading the features of
motherboards below.

1-1 Feature of motherboard

PT800 series motherboards are designed for Intel Pentium 4 Socket-478
400MHz/533MHz/800MHz Front Side Bus Frequency CPUs and the memory size
expandable to 3.0GB.
By using VIA PT800 chipset which provides 800/533/400MHz Front Side Bus frequency
and DDR266/333/400 SDRAM support as a obvious further step to the next generation of
400/533/800MHz processors. PT800 series motherboards also offer ULTRA ATA 133
and Serial ATA RAID 0, 1 functions to provide speedier HDD throughout that boosts
overall system performance.
Integrated AC’97 CODEC audio on system supports 6 channel speaker for 3D Surround
Effect which is fully compatible with Sound Blaster Pro® that gives you the best sound
quality and compatibility. AGP 8X slot enables more complex models and detailed
textures with AGP 8X graphic accelerators which creates richer and more lifelike virtual
environments. VIA VT6103 LAN PHY supports 10/100Mbps data transfer rate full duplex,
half duplex operation. USB control as well as capability of expanding to 8 USB function
ports support USB2.0/1.1 Devices.
Built-in hardware monitor function will monitor and protect your computer which is the
special design in hardware for protecting Pentium 4 CPU from burned, and will shutdown
power supply automatically when CPU is overheated or the CPU cooling fan is not
working.
Minor adjustable DDR memory 2.5V Voltage, AGP 1.5V Voltage, and other special
functions allows user to increase CPU Host clock step by step by setting up BIOS to
approach over clocking and increasing stability of the system.
