Upgrading and ESD precautions
WARNING
Unplug the system before carrying out the procedures described in this document. Failure
to disconnect power before you open the system can result in personal injury or
equipment damage. Hazardous voltage, current, and energy levels are present in this
product. Power switch terminals can have hazardous Voltages present even when the
power switch is off.
The procedures assume familiarity with the general terminology associated with personal
computers and with the safety practices and regulatory compliance required for using and
modifying electronic equipment.
Do not operate the system with the cover removed. Always replace the cover before
turning on the system.
As the colours of the wires in the mains lead of this computer may not correspond with the coloured
markings identifying the terminals in your plug proceed as follows:
The wire which is coloured green-and-yellow must be connected to the terminal in the plug which is marked
by the letter E or by the safety Earth symbol Ω or coloured green or green-and-yellow.
The wire which is coloured blue must be connected to the terminal which is marked with the letter N or
coloured black.
The wire which is coloured brown must be connected to the terminal which is marked with the letter L or
coloured red.
Make sure you are earthed and free of static charge before you open the computer case. If you are
unsure about upgrading your computer, return it to Viglen so a qualified engineer can perform the
upgrade.

Page 4
STEPS TO TAKE TO PREVENT STATIC DISCHARGE:
1. The best way to prevent static discharge is to buy an anti-static strap from your local electrical
shop. While you are wearing the strap and it is earthed, static charge will be harmlessly bled to
ground.
2. Do not remove the component from its anti-static protective packaging until you are about to
install it.
3. Hold boards by the edges - try not to touch components / interface strips etc.
Note:
We recommend that you return your computer to the service department for upgrading. Any work
carried out is fully guaranteed. Upgrades should only be carried out by persons who are familiar
with handling IC's, as incorrect installation will invalidate the guarantee.

• Jumper settings
CAUTION Do not move any jumpers with the power on. Always turn off the power and unplug the
power cord from the computer before changing a jumper setting. Otherwise, the board could be
damaged.
BIOS Setup Configuration Jumper (J7J3) Settings
The 3-pin jumper block determines the BIOS Setup program's mode. The table below describes the jumper
settings for the three modes: normal, configure, and recovery. When the jumper is set to configure mode
and the computer is powered-up, the BIOS compares the processor version and the microcode version in
the BIOS and reports if the two match.
Table 4.
Function/Mode Jumper Setting Configuration
Normal 1-2
Configure 2-3
Recovery None

The BIOS uses current configuration information and passwords for
booting.
After the POST runs, Setup runs automatically. The maintenance
menu is displayed.
The BIOS attempts to recover the BIOS configuration. A recovery
diskette is required.

System Memory
The boards have four DIMM sockets and support the following memory features:
• 1.8 V DDR2 SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 4 GB maximum total system memory total amount of addressable memory.
• Remove the PCI Express x16 video card before installing or upgrading memory to avoid
interference with the memory retention mechanism.
• To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to accurately
configure memory settings for optimum performance. If non-SPD memory is installed, the
BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted or the DIMMs may not function under the determined frequency.
The following table lists the supported DIMM configurations.

•Memory Configurations
The Intel 82915G GMCH supports two types of memory organization:
• Dual channel (Interleaved) mode. This mode offers the highest throughput for real world
applications. Dual channel mode is enabled when the installed memory capacities of both
DIMM channels are equal. Technology and device width can vary from one channel to the
other but the installed memory capacity for each channel must be equal. If different speed
DIMMs are used between channels, the slowest memory timing will be used.
• Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth
operation for real world applications. This mode is used when only a single DIMM is installed
or the memory capacities are unequal. Technology and device width can vary from one
channel to the other. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
NOTE
The DIMM0 sockets of both channels are blue. The DIMM1 sockets of both channels are black.

Page 12
Dual Channel (Interleaved) Mode Configurations
Figure 7 shows a dual channel configuration using two DIMMs. In this example, the DIMM0
(blue) sockets of both channels are populated with identical DIMMs.
Figure 7. Dual Channel (Interleaved) Mode Configuration with Two DIMMs
Figure 8 shows a dual channel configuration using three DIMMs. In this example, the combined
capacity of the two DIMMs in Channel A equal the capacity of the single DIMM in the DIMM0
(blue) socket of Channel B.
Figure 8. Dual Channel (Interleaved) Mode Configuration with Three DIMMs
Figure 9 shows a dual channel configuration using four DIMMs. In this example, the combined
capacity of the two DIMMs in Channel A equal the combined capacity of the two DIMMs in
Channel B. Also, the DIMMs are matched between DIMM0 and DIMM1 of both channels.
Figure 9. Dual Channel (Interleaved) Mode Configuration with Four DIMMs
Page 12 of 17
Page 13
Single Channel (Asymmetric) Mode Configurations
NOTE
Dual channel (Interleaved) mode configurations provide the highest memory throughput.
Figure 10 shows a single channel configuration using one DIMM. In this example, only the
DIMM0 (blue) socket of Channel A is populated. Channel B is not populated.
Figure 10. Single Channel (Asymmetric) Mode Configuration with One DIMM
Figure 11 shows a single channel configuration using three DIMMs. In this example, the combined
capacity of the two DIMMs in Channel A does not equal the capacity of the single DIMM in the
DIMM0 (blue) socket of Channel B.
Figure 11. Single Channel (Asymmetric) Mode Configuration with Three DIMMs
You can install from 128MB to 4GB of memory in the motherboard DIMM sockets.
The board has four 240-pin DDR2 SDRAM DIMM sockets.
The motherboard supports the following memory features:
• 240-pin 1.8volt DIMMs with gold-plated contacts.
• Non-ECC (64-bit) or ECC (72-bit) memory.
• 128MB, 256MB, 512MB, 1GB and 2GB (in the future) modules.
When adding memory, follow these guidelines:
• The BIOS detects the size and type of installed memory.
• For ECC operation to become available all installed memory must be ECC and you must
enable the ECC Configuration feature in the BIOS Setup program.
Note:
DDR SDRAM’s must meet the Version 1.0 June 2000 JEDEC Solid State Technology
Association specifications for DDR200/266 SDRAM.
To install DIMMs, follow these steps:
1. Observe the precautions in “Upgrading and ESD precautions”. Turn off the computer and
all peripheral devices.
2. Remove the computer cover and locate the DIMM sockets.
3. Holding the DIMM by the edges, remove it from its antistatic package.
4. Make sure the clips at either end of the socket are pushed away from the socket.
5. Position the DIMM above the socket. Align the two small notches in the bottom edge of
the DIMM with the keys in the socket. Insert the bottom edge of the DIMM into the socket.
6. When the DIMM is seated, push down on the top edge of the DIMM until the retaining clips
at the ends of the socket snap into place. Make sure the clips are firmly in place.
7. Replace the computer cover.
8. If you installed a DIMM with ECC memory, start the computer and use the ECC
Configuration feature in Setup to enable the use of ECC.
