Introducing the Motherboard
Introduction
Thank you for choosing the G31T-M motherboard. This motherboard is a high performance, enhanced function motherboard designed to support the LGA775 socket
Intel® Wolfdale/Core™ 2 Duo processors for high-end business or personal desktop markets.
The motherboard incorporates the G31 Northbridge (NB) and ICH7 Southbridge (SB) chipsets. The Northbridge supports a Front Side Bus (FSB) frequency of 1333/ 1066/800 MHz using a scalable FSB Vcc_CPU. The memory controller supports DDR2 memory DIMM frequencies of 800/667. It supports two DDR2 Sockets with up to maximum memory of 4 GB. DDR2 Maximum memory bandwidth of 12.8 GB/ s in dual-channel symmetric mode assuming DDR2 800 MHz. High resolution graphics via one PCI Express slot, intended for Graphics Interface, are fully compliant to the PCI Express Base Specification revision 1.1.
The ICH7 Southbridge supports two PCI slots which are PCI 2.3 compliant. In addition, one PCI Express x1 slot is supported, fully compliant to the PCI Express Base Specification, Revision 1.0a. It implements an EHCI compliant interface that provides 480 Mb/s bandwidth for eight USB 2.0 ports. One onboard IDE connector supports 2 IDE devices in Ultra ATA 100/66/33 mode. The Southbridge integrates a Serial ATA host controller, supporting four SATA ports with maximum transfer rate up to 3.0 Gb/s each.
The motherboard is equipped with advanced full set of I/O ports in the rear panel, including PS/2 mouse and keyboard connectors, COM1, VGA1 port, four USB ports, one optional LAN port, and audio jacks for microphone, line-in and 6/8-channel (optional) line-out.
Under ECS validation, G31T-M is able to support FSB1333 MHz.

Installing the Motherboard
Safety Precautions
•Follow these safety precautions when installing the motherboard
•Wear a grounding strap attached to a grounded device to avoid damage from static electricity
•Discharge static electricity by touching the metal case of a safely grounded object before working on the motherboard
•Leave components in the static-proof bags they came in
•Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies with the specifications for the Micro ATX system case. First, some features on the motherboard are implemented by cabling connectors on the motherboard to indicators and switches on the system case. Make sure that your case supports all the features required. Secondly, this motherboard supports one or two floppy diskette drives and two enhanced IDE drives. Make sure that your case has sufficient power and space for all drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O template in the case matches the I/O ports installed on the rear edge of the motherboard.
This motherboard carries a Micro ATX form factor of 244 x 200 mm. Choose a case that accommodates this form factor.
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in a case.
Most system cases have mounting brackets installed in the case, which correspond the holes in the motherboard. Place the motherboard over the mounting brackets and secure the motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion slots on your motherboard.
Installing the Motherboard

Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with more than one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on the correct pins.
The illustrations show a 2-pin jumper. |
|
|
When the jumper cap is placed on both |
|
|
pins, the jumper is SHORT. If you re- |
|
|
move the jumper cap, or place the jumper |
|
|
cap on just one pin, the jumper is OPEN. |
SHORT |
OPEN |
|
This illustration shows a 3-pin jumper.
Pins 1 and 2 are SHORT.

1.To avoid the system instability after clearing CMOS, we recommend users to enter the main BIOS setting page to “Load Optimal Defaults” and then “Save Changes and Exit”.
2.Make sure the power supply provides enough 5VSB voltage before selecting the 5VSB function.
3.It is required that users place the USBPWR_F & USBPWR_R cap onto 2-3 pin rather than 1-2 pin as default if you want to wake up the computer by USB/PS2 KB/Mouse.

Connecting Case Components
After you have installed the motherboard into a case, you can begin connecting the motherboard components. Refer to the following:
1Connect the CPU cooling fan cable to CPU_FAN.
2Connect the system cooling fan connector to SYS_FAN.
3Connect the case switches and indicator LEDs to the F_PANEL1.
4Connect the case speaker cable to SPK1.
5Connect the standard power supply connector to ATX1.
6Connect the auxiliary case power supply connector to ATX12V1.
Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can both be connected to the ATX1 connector. With the 20-pin power cable, just align the 20-pin power cable with the pin 1 of the ATX1 connector. However, using 20-pin power cable may cause the system to become unbootable or unstable because of insufficient electricity. A minimum power of 300W is recommended for a fully-configured system.
With ATX v1.x power supply, users please note that when installing 20-pin power cable, the latch of power cable falls on the left side of the ATX1 connector latch, just as the picture shows.
20-pin power cable
With ATX v2.x power supply, users please note that when installing 24-pin power cable, the latches of power cable and the ATX1 match perfectly.
