15. Although this motherboard offers stepless control, it is not recom-
mended to perform over-clocking. Frequencies other than the recom-
mended CPU bus frequencies may cause the instability of the system
or damage the CPU.
16. 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.
17. ASRock WiFi-802.11n module and RAID / AHCI functions are not
supported under Windows® 2000 OS. It is recommended to use IDE
mode under Windows® 2000. Please refer to page 66 of “User Manual”

Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
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
antstatic pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the
motherboard to the chassis, please do not over-tighten the
screws! Doing so may damage the motherboard.

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.

Installation of CPU Fan and Heatsink
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 2/3,No. 4).
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.

This motherboard provides four 240-pin DDR2 (Double Data Rate 2)DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR2DIMM pair in the slots of the same color. In other words, you have to install
identicalDDR2 DIMM pair in Dual Channel A (DDRII_A1 and DDRII_B1; Yellow
slots; see p.2/3No.6) or identicalDDR2DIMM pair in Dual Channel B(DDRII_A2
andDDRII_B2; Orange slots; see p.2/3No.7), so that Dual Channel Memory Tech-
nology can be activated. This motherboard also allows you to install fourDDR2
DIMMs for dual channel configuration, and please install identicalDDR2DIMMs in
all four slots.You may refer to theDual Channel Memory Configuration Table below.

(3)* Populated Populated Populated Populated
* For the configuration (3), please install identicalDDR2DIMMs in all four slots.
1. If you want to install two memory modules, for optimal compatibil-
ity and reliability, it is recommended to install them in the slots of
the same color. In other words, install them either in the set of
yellow slots (DDRII_A1 and DDRII_B1), or in the set of orange
slots (DDRII_A2 and DDRII_B2).
2. If only one memory module or three memory modules are in-
stalled in the DDR2 DIMM slots on this motherboard, it is unable to
activate the Dual Channel Memory Technology.
3. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDRII_A1 and DDRII_A2, it is unable to activate the Dual Channel
Memory Technology .
4. It is not allowed to install a DDR memory module into DDR2 slot;
otherwise, this motherboard and DIMM may be damaged.

Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock aDIMM slot by pressing the retaining clips outward.
Step 2. Align aDIMM on the slot such that the notch on the DIMM 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 theDIMM is properly seated.

This motherboard supports CrossFireTM feature. CrossFireTM technology offers the most
advantageous means available of combining multiple high performance Graphics
Processing Units (GPU) in a single PC. Combining a range of different operating modes
with intelligent software design and an innovative interconnect mechanism, CrossFireTM
enables thehighestpossible levelof performance andimagequalityinany3Dapplication.
Currently CrossFireTM feature is supported with Windows®XP with Service Pack 2 and
VistaTM OS. Please check AMDwebsite forATITM CrossFireTM driver updates.
What graphics cards work with CrossFireTM?
A complete CrossFireTM system requires a CrossFireTM Ready motherboard, a
CrossFireTM Edition graphics card and a compatible standard Radeon
(CrossFireTM Ready) graphics card from the same series, or two CrossFireTM
Ready cards. This applies to cards from ATITM or any of its partners. Please refer to
