1-2 Mainboard Features
Features Brief Introduction
2AthlonTM 64 Processor
The AMD AthlonTM 64 processor family is designed to support performance
desktop. It provides a high performance HyperTransportTM link to I/O, as well
as a single 64-bit high-performance DDR memory controller.
For more information about all the new features AthlonTM 64 Processor deliver, check out
the AMD website at http://www.amd.com
2Chipset
The board is designed with VIA chipset, K8T800 as North Bridge and VT8237 as
South Bridge, providing a feature rich and scalable platform. The K8T800 North
Bridge is designed with an ultra fast HyperTransport link to the AthlonTM 64 and
comes equipped with AGP 8X features for VGA card expansion.
The K8T800 North Bridge connects to the VT8237 South Bridge through the fast
Ultra V-Link connection at 1.06GB/s. With support for two Serial ATA channels
at 150MB/s bandwidth, integrated RAID (0, 1, 0+1 & JBOD) capability as well as
up to eight USB 2.0 ports, the VT8237 offers the highest possible peripheral
performance for professional users. Additional features include a VIA MAC for
10/100Mbps Fast Ethernet, integrated PCI support.
2Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 3.0 specification. This
new specification enhances the functionality of the original AGP specification
by allowing 8X data transfers ( 8 data samples per clock) resulting in maximum
bandwidth of 2.1GB/s. Only 1.5V AGP cards are supported.
2Ultra ATA100/133
The mainboard provides an Ultra ATA100/133 Bus Master IDE controller. This
controller supports Ultra ATA100/133 protocols which are ideal to support
demanding applications such as real-time video, multimedia, and a high perfor-
mance operating system. A new IDE cable is required for Ultra ATA100/133.

2Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system
operation and status. The features include CPU temperature, voltage and fan
speed in RPMs.
210/100 LAN (Optional)
This mainboard is mounted with a ethernet LAN PHY. It allows the mainboard to
connect to a local area network by means of a network hub.
2GbE LAN (Optional)
This mainboard is optionally mounted with a Gigabit ethernet LAN chipset. The
new Gigabit Ethernet LAN allows data transmission at 1,000 megabits per second
(Mbps), which runs 10 times faster than conventional 10/100BASE-T Ethernet
LANs.
2Serial ATA
Support Serial ATA, an evolutionary replacement for Parallel ATA IDE storage
interface .Increases the peak data transfer speed up to 150MB/sec and allows
future enhancements to the computing platform.
2More S-ATA (Optional)
Extra SiI3114 S-ATA controller onboard for more S-ATA ports, complete with
RAID function, 4 S-ATA ports with 150MB/sec supporting RAID 0, 1 , 10, 5.
2USB2.0
A popular USB standard for plugging in peripherals with up to 480Mbps transfer
speed while maintaining backward compatibility with older USB1.1 device.
28ch
Delivers 8 channel audio to bring you the latest in audio realism from DVD
movies and games. Perfect for your home theatre system.

Installation
Page 3-4
Step 5
Align pin 1 on the CPU with pin 1 on
the CPU socket as shown in the
illustration above. The CPU is keyed to
prevent incorrect insertion. Do not force
the processor into the socket. If it does
not go in easily, check for mis-orienta-
tion and reinsert the CPU.
Make sure the processor is fully
inserted into the socket.
<Figure 5> <Figure 6>
Step 6
Close the socket by lowering and
locking the actuation lever.
Step 7
Apply thermal compound to the top of
the CPU and install the heatsink as
shown.
<Figure 7> <Figure 8>
Step 8
Press the clips in the direction of the
arrows shown in Figure 8 to secure the
assembly to the CPU socket.
