Installation
You are now ready to install your motherboard. The mounting hole pattern of the Thunder K7X
Pro matches the E-ATX (Extended ATX) system board specifications. Your chassis should
support a standard E-ATX motherboard form factor.
How to install our products right… the first time
The first thing you should do is read this user’s manual. It contains important information that will
make configuration and setup much easier. Here are some precautions you should take when
installing your motherboard:
(1) Ground yourself properly before removing your motherboard from the antistatic bag.
Unplug the power from your computer power supply and then touch a safely grounded
object to release static charge (i.e. power supply case). For the safest conditions, TYAN
recommends wearing a static safety wrist strap.
(2) Hold the motherboard by its edges and do not touch the bottom of the board, or flex the
board in any way.
(3) Avoid touching the motherboard components, IC chips, connectors, memory modules,
and leads.
(4) Place the motherboard on a grounded antistatic surface or on the antistatic bag that the
board was shipped in.
(5) Inspect the board for damage.
The following pages include details on how to install your motherboard into your chassis, as well
as installing the processor, memory, disk drives and cables.

2.16 –Mounting the Motherboard
Before installing your motherboard, make sure your chassis has the necessary motherboard
support studs installed. These studs are usually metal and are gold in color. Usually, the chassis
manufacturer will pre-install the support studs. If you’re unsure of stud placement, simply lay the
motherboard inside the chassis and align the screw holes of the motherboard to the studs inside
the case. If there are any studs missing, you will know right away since the motherboard will not
be able to be securely installed.
Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable, TYAN
recommends using metal studs with screws that will fasten the motherboard more securely
in place.
Below is a chart detailing what the most common motherboard studs look like and how they
should be installed.
TIP: Use metal studs if possible, as they hold the motherboard into place more securely than
plastic standoffs.

14
http://www.TYAN.com
2.17 –Installing the Memory
Before attempting to install any memory, make sure that the memory you have is compatible with
the motherboard as well as the processor. For example, while PC1600 DDR modules are
compatible with all DDR based motherboards, they will not work if you are required to run the
Front Side Bus at 133MHz. For this, PC2100 DDR modules are required. Critically important is
whether you’re using the recommended memory for the current board you have. For this
information, please check TYAN’s web site at: www.TYAN.com
The following diagram shows the types of RAM modules you may encounter depending on your
board:
Here are a few key points to note before installing memory into your Thunder K7X Pro:
•Always install memory in order, starting with DIMM Bank1.
•At least ONE Registered DDR SDRAM module must be installed for the system to
turn on and POST (power on self test)
•128MB, 256MB, 512MB and 1GB Registered PC2100/PC1600 DDR SDRAM memory
modules are supported
•All installed memory will be automatically detected
•The Thunder K7X Pro supports up to 4GB.*
* The AMD-760 MPX requires a portion of memory to be reserved for PCI devices. Allocation for
these devices is dependent on the number of PCI devices installed, and option ROM for each
device. Common configurations will see 3.5GB to 3.8GB of available memory.

15
http://www.TYAN.com
Memory Installation Procedure
When you install the memory modules, make sure the module aligns properly with the memory
slot. The modules are keyed to ensure that it is inserted only one way. The method of installing
memory modules are detailed by the following diagrams.
Once the memory modules are firmly seated in the slot, two latches on either side will close and
secure the module into the slot. Sometimes you may need to close the latches yourself.
To remove the memory module, simply push the latches outwards until the memory module pops
up. Then simply remove the module.
NOTE YOU MUST unplug the power connector to the motherboard before performing
system hardware changes, to avoid damaging the board or expansion device.

16
http://www.TYAN.com
2.18 –Installing the Processor and Heatsinks
Your brand new Thunder K7X Pro supports the latest processor technologies from AMD.
However, only Athlon MP processors are certified and supported with this motherboard.
Check our website for latest processor support.
NOTE If using a single processor, we recommend it be installed in socket CPU1.
Duron processors, Athlon C (Thunderbird), and Athlon XP processors are not certified or
supported in single or dual mode. Also, mixing different types of processors together is not
supported as damage to your processors, motherboard or both may occur. TYAN is not liable for
damage as a result of operating an unsupported configuration.
The diagram is provided as a visual guide to help you install socket processors and may not be an
exact representation of the processors you have.
1. Lift the lever on the socket until it is approximately 90o or as far back as possible
to the socket.
2. Align the processor with the socket. There are keyed pins underneath the processor to
ensure that the processor’s installed correctly.
3. Seat the processor firmly into the socket by gently pressing down until the processor
sits flush with the socket.
4. Place the socket lever back down until it locks into place.
5. Your processor is installed.
6. Repeat these steps for the second processor if you are using two processors.
Take care when installing processors as they have very fragile connector pins below the
processor and can bend and break if inserted improperly.
Heatsink Installation
After you are done installing the processor(s), you should proceed to installing the heatsinks.
Heatsinks will ensure that the processors do not overheat and continue to operate at maximum
performance for as long as you own them. Overheated processors are also dangerous to the
health of the motherboard.
Because there are many different types of heatsinks available from many different manufacturers,
a lot of them have their own method of installation. For the safest method of installation and
information on choosing the appropriate heatsink, please refer to AMD’s website at
www.amd.com.

17
http://www.TYAN.com
The following diagram will illustrate how to install the most common heatsinks:
First, use thermal compound
(also called heatsink compound
or thermal grease) and apply a
small amount on to the
processor’s core (applying too
much will actually reduce the
cooling) –the small shiny square
in the center of the processor.
You may then use a small soft
plastic tool, like a credit card to
gently smear a thin layer of
heatsink compound as evenly as
you can across the core.
Because one side of the socket
is raised (and usually has
“SOCKET” imprinted into it)
heatsinks have an indent on one
side to secure flush with the
raised side of the socket.
Then clip one side of the
heatsink onto the socket and
then lay the heatsink flat onto
the processor. Then clip the
other end of the heatsink down
either with your finger or by
using a flathead screw driver.
Be sure to carefully observe
which side your heatsink is
seated before securing it down
to avoid damaging the
processor, the heatsink or both.
This is will probably be the most
difficult portion of setting up your
computer so please exercise
caution. TYAN will not accept
responsibility and no warranty
will be given for damage due to
improperly installed heatsinsks.

18
http://www.TYAN.com
Finishing Installing the Heatsink
After you finish installing the heatsink onto the processor and socket, attach the end wire of the
fan (which should already be attached to the heatsink) to the motherboard. The following diagram
illustrates how to connect fans onto the motherboard.
After you’re finished installing all the fans you can connect your drives (hard drives, CD-ROM
drives, etc.) to your motherboard.
2.19 –Attaching Drive Cables
Attaching the IDE drive cable is simple. These cables are “keyed” to only allow them to be
connected in the correct manner. TYAN motherboards have two on-board IDE channels, each
supporting two drives. The black connector designates the Primary channel, while the white
connector designates the Secondary channel.
Attaching IDE cables to the IDE connectors is illustrated below:
Simply plug in the BLUE END of the IDE cable into the motherboard IDE connector, and the other
end(s) into the drive(s). Each standard IDE cable has three connectors, two of which are closer
together. The BLUE connector that is furthest away from the other two is the end that connects to
the motherboard. The other two connectors are used to connect to drives.
Note: Always remember to properly set the drive jumpers. If only using one device on channel, it
must be set as Master for the BIOS to detect it.
TIP: Pin 1 on the IDE cable (usually designated by a colored wire) faces the drive’s power
connector.

19
http://www.TYAN.com
Floppy Drives
Attaching floppy diskette drives are done in a similar manner to hard drives. See the picture below
for an example of a floppy cable. Most of the current floppy drives on the market require that the
cable be installed with the colored stripe positioned next to the power connector. In most cases,
there will be a key pin on the cable which will force a proper connection of the cable.
The first floppy drive (sometimes denoted as
A:) is usually attached to the end of the cable
with the twist in it. Drive B: is usually connected
to the next possible connector on the cable (the
second or third connector after you install Drive
A:).
Refer to your floppy drive’s installation
instructions (if available), or contact your dealer
if you are unsure about how to attach the
floppy drive(s). Remember, you can only have
2 floppy drives connected at any given time.
Below are some symptoms of incorrectly installed floppy drives. While they are minor and
installing them incorrectly doesn’t cause severe problems, it may cause your system to freeze or
crash when trying to read and/or write to diskettes.
Symptoms of incorrectly installed floppy drives
Drive is not automatically detected
Usually caused by faulty cables, cables put in
backwards or a bad floppy drive or
motherboard. Try another floppy drive to verify
the problem if the cable is properly installed or
try replacing the actual cable. Also check to
see if the onboard floppy controller is enabled
in the BIOS setup.
Drive Fail message at bootup The cable, floppy drive or motherboard may be
faulty. Try another drive or cable to verify.
Drive does not power on Check power cable and cabling. Maybe a bad
power supply or drive cable problem.
Drive activity light is constantly on
Usually signifies that the cable on the drive is
on backwards, which is a common issue.
Reverse the cable at the floppy drive end and
try again.

2.20 –Installing Add-In Cards*
Before installing add-in cards, it’s helpful to know if they are fully compatible with your
motherboard. For this reason, we’ve provided the diagrams below, showing the most common
slots that may appear on your motherboard. Not all of the slots shown will necessarily appear on
your motherboard, however, there will be combinations of what you see here.
Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any
add-in cards into any slots if they do not seat in place. It is better to try another slot or return the
faulty card rather than damaging both the motherboard and the add-in card.
TIP: It’s good practice to install add-in cards in a staggered manner, rather than directly adjacent
to each other. This allows air to more easily circulate within the chassis, providing improved
cooling for all installed devices.
NOTE YOU MUST unplug the power connector to the motherboard before performing
system hardware changes, to avoid damaging the board or expansion device.
*Due to the tight PCI 66MHz timing of the AMD-760 MPX chipset, it may be necessary to set the
bus to 33MHZ when using multiple PCI cards. For more information, refer to the AMD 760
System Controller Datasheet (PID# 24416) on the AMD website: www.amd.com.
