Introducing the Mainboard
I
In nt tr ro od du uc ct ti io on n
Thank you for purchasing the SVX400 mainboard. The SVX400 is designed to
accommodate Intel Pentium 4 processors supporting front side bus (FSB)
speeds of 400/533 MHz.
The mainboard is an ATX mainboard that uses a 4-layers printed circuit board
and measures 305 mm x 244 mm.
Based on the highly integrated VIA APOLLO P4X400, this mainboard
incorporates the VIA VT8754 Northbridge and VT8235 Southbridge chipsets
which delivers workstation level performance.
The SVX400 comes with a full set of I/O features conveniently integrated on
the rear I/O panel, including support for PS/2 keyboard and mouse
connectors, two USB ports, a LAN connector, two high-speed serial port, an
EPP/ECP parallel port, audio jacks for microphone, line-in, line-out and CD-in
and a game port, as well as supporting Plug and Play.
For added power and performance, the mainboard achieves the highest
reliability by supporting three 184 pin, 2.5V DDR (Double Data RAM) DIMM
sockets with a total capacity of 12 GB.
The SVX400 offers the ideal platform for building powerful PCs and
workstations.
Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz. Double Data Rate SDRAM
(DDR SDRAM) doubles the rate to 1.6 GBps and 2.7 GBps. DDR
SDRAM uses additional power and ground lines and requires 184-pin
DIMM modules rather than the 168-pin DIMMs used by SDRAM.

Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a
momentary-contact switch that is normally open. When the switch is closed,
the board resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply
recognizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated
speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can
permanently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 478 processor socket. When choosing a
processor, consider the performance requirements of the system.
Performance is based on the processor design, the clock speed and system
bus frequency of the processor, and the quantity of internal cache memory
and external cache memory.
13

CPU Installation Procedure

9. Swing both lock levers on top of the cooling fan to their opposite sides to
secure the cooling fan on top of the heatsink.
10. Connect the CPU Cooling Fan
power cable to the CPUFAN1
connector.
Notes: • To achieve better airflow rates and heat dissipation, we suggest that
you use a high quality fan with 4800 rpm at least.
• CPU fan and heatsink installation procedures may vary with the type
of CPU fan/heatsink supplied. The form and size of fan/heatsink may
also vary.
15

Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Double Data Rate
(DDR) SDRAM memory modules. The memory chips must be standard or
registered SDRAM (Synchronous Dynamic Random Access Memory).
The memory bus can run at 100/133/166 MHz. If your processor operates
over a 100 MHz system bus, you can install DDR200 or DDR266/DDR333
memory modules that operate over a 100/133/166 MHz memory bus.
The mainboard accommodates three memory modules. You must install at
least one module in any of the three slots. Each module can be installed with
up to 4 GB of memory; total memory capacity is 12 GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1. This mainboard supports unbuffered DDR SDRAM only. Do not attempt to
insert any other type of DDR SDRAM into the slots.
2. Push the latches on each side of the DIMM slot down.
3. Align the memory module with
the slot. The DIMM slots are
keyed with notches and the
DIMMs are keyed with cutouts
so that they can only be
installed correctly.
4. Check that the cutouts on the
DIMM module edge connector
match the notches in the
DIMM slot.
5. Install the DIMM module into
the slot and press it firmly
down until it seats correctly.
The slot latches are levered
upwards and latch on to the
edges of the DIMM.
6. Install any remaining DIMM modules.
