CAUTION!
1. To support FSB1066, please use DDR400 DIMMs (Double Data Rate 400
MHz). Before installing FSB1066 CPU, please make sure that you have
adjusted the jumpers correctly. The default setting of FSB1 is shorting
pin1 and pin2. However, if you want to support FSB1066 CPU, please
adjust your FSB1 jumper setting, and short pin2 and pin3 (see page 17).
2. About the setting of “Hyper Threading Technology”, please check page 25.
3. Please check the table below for the memory support frequency and its
corresponding CPU FSB frequency.
CPU FSB FrequencyMemory Support Frequency
1066DDR400*
800DDR266, DDR320
533DDR266, DDR333
* When you use an FSB800-CPU on this motherboard, it will run at
DDR320 if you adopt a DDR333 memory module.
4. This motherboard supports Dual Channel Memory Te chnology. Before you
implement Dual Channel Memory Technology, make sure to read the
installation guide of memory modules on page 14 for proper installation.
5. 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 a nd the heatsink when you in stall the PC syste m.
6. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
7. Power Management for USB 2.0 works fine under Microsoft
SP1 / 2000 SP4. It may not work properly under Microsoft
ME.
8. 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 9 for
proper connection.
9. 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
775i65PE is an ATX form factor (12.0" x 9.0", 30.5 x 22.9 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 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 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 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.
775-Pin Socket Overview
Step 1. Open the socket:
Step 1-1. Disengaging the lever by depressing
Lift Lever Up to 90°
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.

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.
It is recommended to use the cap tab to handle and avoid kicking off
the PnP cap.
Step 4. Close the socket:
