Thank you for choosing the G33T-M2 motherboard. This motherboard is a high perfor-
mance, enhanced function motherboard designed to support the LGA775 socket for Intel
Wolfdale/ CoreTM2 Duo processors for high-end business or personal desktop markets.
The motherboard incorporates the G33 Northbridge (NB) and ICH9 Base 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 four DDR2 Sockets with up to maximum
memory of 8 GB. DDR2 memory bandwidth of 12.8 GB/s in dual-channel symmetric mode
assuming DDRII 800. High resolution graphics via one PCI Express slot, intended for
Graphics Interface, is fully compliant to the PCI Express Base Specification revision 1.1.
The ICH9 Base Southbridge supports two PCI slots which are PCI 2.3 compliant. It implements an EHCI compliant interface that provides 480 Mb/s bandwidth for twelve USB 2.0
ports. 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, one serial port (optional), one parallel port (optional), one VGA port, four USB ports, one LAN port (optional), one 1394A port (optional) and audio jacks for microphone, line-in and 8-ch line out.
“Hyper-Threading” technology enables the operating system into thinking it’s hooked
up to two processors, allowing two threads to be run in parallel, both on separate
“logical” processors within the same physical processor.

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. 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 an Micro ATX form factor of 244 x 244 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 remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT
