Chapter 2: Board Installation

Precautions: The Thunder K8HM supports SSI, EPS12V type power supplies

(24pin + 8pin) and will not operate with any other types. For proper power
supply installation procedures see page 37.

DO NOT USE ATX 2.x or ATXGES power supplies as they will damage the
board and void your warranty.

How to install our products right… the first time
The first thing you should do is reading 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.

NOTE

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN

DAMAGED.

2.4 - Installing the Processor(s)

Your brand new Thunder K8HM supports the latest 64-bit processor technology
from AMD. Only the AMD Opteron

™

processor 200 series are certified and
supported with this motherboard. Check our website for latest processor
support. http://www.tyan.com

NOTE

If using a single processor, it MUST be installed in socket
CPU1. When using a single processor only CPU1 memory
banks are addressable.

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.

Step 1: Lift the lever on the socket until it is approximately 90o or as far back as
possible to the socket.
Step 2: Align the processor with the socket. There are keyed pins underneath
the processor to ensure that the processor’s installed correctly.
Step 3: Seat the processor firmly into the socket by gently pressing down until
the processor sits flush with the socket.
Step 4: Place the socket lever back down until it locks into place. The
installation is finished.
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.

http://www.tyan.com

23

2.5 - Heatsink Retention Frame Installation

After you are done installing the processor(s), you should proceed with installing
the retention frame and heatsink. The CPU heatsink 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 dangerous to the
motherboard.

The backplate assembly prevents excessive motherboard flexing in the area
near the processor and provides a base for the installation of the heatsink
retention bracket and heatsink.

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, use heatsinks validated by AMD. Please refer to AMD’s website at

www.amd.com.

The following diagram will illustrate how to install the most common CPU back
plates:

1. Mounting screws

2. Heatsink retention frame

3. CPU socket

4. Motherboard PCB

5. Adhesive insulator
material

6. Backplate assembly

NOTE: Please see next
section for specific
instructions on how to install
mounting bracket.

http://www.tyan.com

24

2.6 - Thermal Interface Material

There are two types of
thermal interface materials
designed for use with the
AMD Opteron processor.

The most common material
comes as a small pad
attached to the heatsink at
the time of purchase. There
should be a protective cover
over the material. Take care
not to touch this material.
Simply remove the protective
cover and place the heatsink
on the processor.

The second type of interface
material is usually packaged
separately. It is commonly
referred to as ‘thermal
compound’. Simply apply a
thin layer on to the CPU lid
(applying too much will
actually reduce the cooling).

NOTE

Always check with the manufacturer of the heatsink &
processor to ensure the Thermal Interface material is
compatible with the processor & meets the manufacturer’s
warranty requirements

http://www.tyan.com

25

2.7 - Heatsink Installation Procedures

Type A: CAM LEVER (TYPE) INSTALLATION

1. After placing backplate and
interface material under motherboard
place heatsink retention frame on top
of motherboard. Align plastic retention
bracket screw holes with CPU back­plate standoffs.
Tighten screws to secure plastic
retention bracket. Repeat for the other
side. DO NOT OVER TIGHTEN.

2. After tightening screws secure
metal clip to plastic retention bracket
center tab. Repeat for the other side
of heatsink.

3. After securing metal clip to plastic
retention bracket center tab, push
down on plastic clip to lock plastic clip
to side tab.

http://www.tyan.com

26

Type B: SCREW RETENTION TYPE HEATSINK

1. After placing CPU back-plate and
adhesive interface material under
motherboard, place heatsink
retention frame on top of
motherboard. Align heatsink retention
frame screw hole with backplate
assembly standoffs. Place heatsink
inside plastic retention bracket. Place
metal clip over retention frame tab.
Repeat for other side.

2. Insert screw through metal clip.

BE SURE METAL CLIP IS LOCKED
ONTO RETENTION FRAME TAB.

3. Tighten screw through metal
clip. Repeat on the other si

de.

DO NOT OVER TIGHTEN.

http://www.tyan.com

27

Finishing Installing the Heatsink

After you have finished 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.

Once you have finished installing all the fans you can connect your drives (hard
drives, CD-ROM drives, etc.) to your motherboard.

http://www.tyan.com

28

2.8 - Tips on Installing Motherboard in Chassis

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 are 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.

Pay attention when installing board in chassis. Some components are
near the mounting holes and can be damaged.

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.

http://www.tyan.com

29

2.9 - 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.
The following diagram shows common types of DDR SDRAM modules:

Key points to note before installing memory into Thunder K8HM:

For optimal dual-channel DDR operation, always install memory in pairs
beginning with CPU1_DIMMA3 and CPU1_DIMMB3. Memory modules of
the same type and density are required for dual-channel DDR operation.
Mismatched memory may cause system instability.

When the DIMMs are not fully populated, the system can support 256MB,
512MB, 1GB and 2GB of PC2100/2700/ Registered memory modules.

However, if 8 DIMMs and 16 DIMMs are populated for single and dual

CPU operation respectively, the system can only support up to PC2100.

All installed memory will be automatically detected.
The Thunder K8HM S3892 supports up to 32GB of memory.

http://www.tyan.com

30

To correctly install the memory in pairs (DIMMA# + DIMMB#), refer to the
following table for supported population options.
