CAUTION!
1. About the setting of “Hyper ThreadingTechnology”, please check page 30.
2. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 26 for details.
3. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
4. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
5. For microphone input, this motherboard supports both stereo and mono
modes. For audio output, this motherboard supports 2-channel, 4-channel,
6-channel, and 8-channel modes. Please check the table on page 11 for
proper connection.
6. Power Management for USB 2.0 works fine under Microsoft®Windows®
VistaTM / XP 64-bit / XP SP1 or SP2 / 2000 SP4.
7. Microsoft®Windows®VistaTM driver is not ready yet. We will update it to

Chapter 2 Installation
775Twins-PT890 is an ATX form factor (12.0" x 8.3", 30.5 x 21.1 cm) motherboard.
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
2.1 Screw Holes2.1 Screw Holes
2.1 Screw Holes2.1 Screw Holes
2.1 Screw Holes
Place screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions2.2 Pre-installation Precautions
2.2 Pre-installation Precautions2.2 Pre-installation Precautions
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use
a grounded wrist strap or touch a safety grounded object before you handle
components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched off or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

2.3 775-LAND CPU Installation2.3 775-LAND CPU Installation
2.3 775-LAND CPU Installation
For the installation of Intel 775-LAND CPU,
please follow the steps below.
Before you insert the 775-LAND CPU into the socket, please check if
the CPU surface is unclean or if there is any bent pin on the socket.
Do not force to insert the CPU into the socket if above situation is
found. Otherwise, the CPU will be seriously damaged.
Step 1. Open the socket:
Step 1-1. Disengaging the lever by depressing
down and out on the hook to clear
retention tab.
Step 1-2. Rotate the load lever to fully open po-
sition at approximately 135 degrees.
Step 1-3. Rotate the load plate to fully open po-
sition at approximately 100 degrees.
Step 2. Insert the 775-LAND CPU:
Step 2-1. Hold the CPU by the edges where are
marked with black lines.
Step 2-2. Orient the CPU with IHS (Integrated
Heat Sink) up. Locate Pin1 and the two
orientation key notches.

For proper inserting, please ensure to match the two orientation key
notches of the CPU with the two alignment keys of the socket.
Step 2-3. Carefully place the CPU into the socket
by using a purely vertical motion.
Step 2-4. Verify that the CPU is within the socket
and properly mated to the orient keys.
Step 3. Remove PnP Cap (Pick and Place Cap):
Use your left hand index finger and thumb to
support the load plate edge, engage PnP cap
with right hand thumb and peel the cap from the
socket while pressing on center of PnP cap to
assist in removal.
1. It is recommended to use the cap tab to handle and avoid kicking
off the PnP cap.
2. This cap must be placed if returning the motherboard for after
service.
Step 4. Close the socket:
Step 4-1. Rotate the load plate onto the IHS.
Step 4-2. While pressing down lightly on load
plate, engage the load lever.
Step 4-3. Secure load lever with load plate tab
under retention tab of load lever.

Installation of CPU Fan and HeatsinkInstallation of CPU Fan and Heatsink
Installation of CPU Fan and Heatsink
This motherboard is equipped with 775-Pin socket that supports Intel 775-LAND CPU.
Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU
to dissipate heat. Before you installed the heatsink, you need to spray thermal
interface material between the CPU and the heatsink to improve heat dissipation.
Ensure that the CPU and the heatsink are securely fastened and in good contact with
each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see
page 10, No. 3).
For proper installation, please kindly refer to the instruction manuals of your
CPU fan and heatsink.
Below is an example to illustrate the installation of the heatsink for 775-LANDCPU.
Step 1. Apply thermal interface material onto center
of IHS on the socket surface.
Step 2. Place the heatsink onto the socket. Ensure
fan cables are oriented on side closest to the
CPU fan connector on the motherboard
(CPU_FAN1, see page 10, No. 3).
Step 3. Align fasteners with the motherboard
throughholes.
Step 4. Rotate the fastener clockwise, then press
down on fastener caps with thumb to install
and lock. Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise,
the heatsink cannot be secured on the motherboard.
Step 5. Connect fan header with the CPU fan
connector on the motherboard.
Step 6. Secure excess cable with tie-wrap to ensure
cable does not interfere with fan operation or
contact other components.

Installation of Memory Modules (DIMM)
This motherboard is equipped with two 184-pinDDR (DoubleData Rate) DIMM slots
and two 240-pinDDRII (DoubleData Rate) DIMM slots.
1. It is not allowed to install a DDR memory module into DDRII slot or
a DDRII memory module into DDR slot; otherwise, this motherboard
and DIMM may be damaged.
2. It is not allowed to install both DDR and DDRII memory modules to
this motherboard at the same time; otherwise, this motherboard and
DIMM may be damaged.
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Installing a DIMMInstalling a DIMM
Installing a DIMMInstalling a DIMM
Installing a DIMM
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.
