3.0GB.
This motherboard use the latest VIA KT333 chipset, appling
266MHz (Double Data Rate) Front Side Bus frequency and 266MHz
memory interface delivers a clear upgrade path to the future
generation of 266MHz processors, PC-1600/PC-2100/PC-2700
DDR DRAM. The 7KT333 motherboard offers ULTRA ATA 100/
133 to provide speedier HDD throughout that boosts overall
system performance.
It is ideal for multi-tasking and fully supporting MS-DOS,
Windows, Windows NT , Windows ME, Windows 2000, Novell,
OS/2, Windows95/98, Windows 98SE, Windows XP, UNIX, Liunx
, SCO UNIX etc. This manual also explains how to install the
mainboard for operation, and how to setup your CMOS
configuration with the BIOS setup program.

The motherboard operates with Socket 462 for AMD
AthlonTM and DuronTM processor. The CPU should always has a
Heat Sink and cooling fan attached to prevent overheating.
CPU Installation Procedures: Socket 462
1. Pull the lever sideways away from the socket then raise
the lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or
cut edge in the CPU. Match Pin 1 with the white dot or
cut edge then insert the CPU.
3. Press the lever down to complete installation.
4. Make sure the spec of the heat sink is good enough.
5. Please lock the fan on CPU very carefully, or you
will damage the resistor array even circuit line
on the motherboard.

The motherboard supports a maximized 3GB memory. It provides
three 184-pin unbuffered DDR sockets. It supports 64MB to 1GB
DDR memory module.
DDR SDRAM Access Time: 2.5V Unbuffered PC1600/PC2100/
PC2700 Type required.
DDR SDRAM Type: 64MB, 128MB, 256MB, 512MB, 1GB DDR
Module. (184 pin)
DDR SDRAM Installation Procedures:
1. The DDR socket has a “Plastic Safety Tab” and the DDR
memory module has an asymmetrical notch”, so the
DDR memory module can only fit into the slot in one
direction.
2. Push the tabs out. Insert the DDR memory modules
into the socket at a 90-degree angle then push down
vertically to fit onto place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DDR memory modules in place.

Note:
1. When you plug or unplug DDR module, you must check
your power supply is off.
2. When using DDR 333MHz memory, please make sure
the CPU Front Side Bus frequency is 266MHz.

1.7.1.3 The Serial Interfaces: COM1 / COM2
The serial interface port is sometimes refered to as an
RS-232 port or an asynchronous communication port. Mice,
printers, modems and other peripheral devices can be
connected to a serial port. The serial port can also be used
to connect your computer system. If you like to transfer
the contents of your hard disk to another system, it can be
accomplished by serial port.
1.7.1.4 Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics
port, the parallel port is almost exclusively used with printers.
The parallel port on your system has a 25-pin, DB 25
connector.
1.7.1.5 Joystick / Midi Connector
You can connect a joystick or game pad to this connector.
1.7.1.6 Audio Port Connectors
Speaker out is a connector for Speakers or Headphones. Line
in is used for external CD player, Tape player, or other audio
devices. Mic is a connector for the microphones.

1.7.2 ATX Power Connector: ATX
This connector supports the power button on-board. Using
the ATX power supply, functions such as Modem Ring Wake-
Up and Soft Power Off are supported on this motherboard .
This power connector supports instant power-on
functionality, which means that the system will boot up
instantly when the power connector is inserted on the board.

1.7.3 Floppy Disk Connector: FDC
This connector supports the provided floppy drive ribbon
cable. After connecting the single end to the board, connect
those two plugs on the other end to the floppy drives.
1.7.4 Hard Disk Connectors: IDE1/IDE2
These connectors support the provided IDE hard disk ribbon
cable. After connecting the single end to the board, connect
those two plugs at the other end to your hard disk.
If you install two hard disks, you must configure the second
drive to Slave mode by setting its jumper settings. BIOS now
supports SCSI device or IDE CD-ROM boot up (see "HDD
Sequence SCSI/IDE First" & "Boot Sequence" in the BIOS
Features Setup of the BIOS SOFTWARE) (Pin 20 is removed

These connectors support cooling fans of 1Amp or
less. Orientate the fans so that the heatsink fins allow
airflow to go across the onboard heat sink(s) instead
of the expansion slots. Depending on the fan
manufacturer, the wiring and plug may be different.
The red wire should be positive, while the black should
be ground. Connect the fan’s plug to the board taking

ATX Power Switch (PW_BN)
The system power is controlled by a momentary switch
connected to this lead. Pushing the button once will switch
the system ON.
Power LED Lead (PW_LED)
The system power LED lights when the system power is on.
Speaker Connector (SPEAKER)
The speaker (onboard or offboard) provides error beep code
information during the Power Self-Test when the computer
cannot use the video interface. The speaker is not connected to
the audio subsystem and does not receive output from the audio
subsystem.
Hard Drive LED Connector (HDLED)
This connector supplies power to the cabinet IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors will cause the LED to light up.
Keyboard Lock (KBLOCK)
The header is for setting keyboard locked.
Reset Switch Lead (RESET)
The connector can be connected to a momentary SPST type
switch that is normally open. When the switch is closed, the
motherboard resets and runs the POST.
SMI Suspend Switch Lead (SMI_LED) (Disabled)
This allows the user to manually place the system into a suspend
mode of Green mode. System activity will be instantly decreased
to save electricity and expand the life of certain components
when the system is not in use. This 2-pin connector (see the
figure) connects to the case-mounted suspend switch. If you do
not have a switch for the connector, you may use the "Turbo
Switch” instead since it does not have a function. If you want to
use this connector, the "Suspend Switch" in the Power
Management Setup of the BIOS SOFTWARE section should be
on the default setting of Enable.
