2-3-3 CPUFAN Detect Control--ISM (Intelligent Shutdown

Master)

As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable, long-term system
operation. And with CPU speed constantly increasing, improper cooling of the system
as a whole can lead to permanent damage. Our motherboard has an unique design –
ISM (Intelligent Shutdown Master) to provide prefect protections right at the very
moment the system cooling should fail, please make good use of it! The following is an
excerpt from a warning AMD released on such issue:

The new PGA (Pin Grid Array) AMD Athlon™ and AMD Duron™ processors have
very different thermal specifications from any preceding AMD processor. Due to
these differences, the AMD Athlon and AMD Duron processors should NEVER run
without a cooler, not even for a few seconds. Doing so will cause the processor to
overheat and fail immediately, resulting in permanent damage. While testing a
processor by booting it up for several seconds without a cooler installed may be
common industry practice, it should never be attempted with the new PGA AMD
Athlon and AMD Duron processors…..

Typically the CPU cooler Assembly comes with FAN (Some with 2 FANS), but even
so, the system cooling can deteriorate within a certain period of time. This will result
in permanent damage to the processor and potentially other key components within the
system. Our powerful ISM (Intelligent Shutdown Master) function will smartly
cut off the power supply once the cooling fan fails and safely secure your CPU and
main board against possible damages.

K7MKLE System Board 13

CAUTIONS:

1. ISM is a 100% hardware solution, no additional software installation is required.
Unlike software solution, ISM will not sacrifice the system performance.

2. Must connect FAN pin of CPU cooler to CPU FAN header.

3. For best protection, in case the system cooling fails, ISM will compulsorily shut
down the computer system without precautions (no matter your system is under
DOS or Windows mode) and inevitably all unsaved data will lose.

4. The default ISM function (JP1) is ‘ON. To disable ISM function, please set JP1
Jumper to ‘OFF’.

5. If the computer system automatically shut down right after being booted up, check
whether the CPU cooler Assembly is connected to CPU FAN or the CPU fan
already failed.

K7MKLE System Board 14

2-4 CPU Installation

The first step in the installation of your CPU is the insertion of the CPU into the 462 pins
CPU socket. Please follow the steps as outlined below carefully to avoid damage to the
CPU.

Avoid Static Electricity

The AMD Athlon and AMD Duron processors and your motherboard contain
sensitive electronic components that can be easily damaged by static electricity.
We recommend that you leave the processor in its original packaging until you are
ready to install it. You should only touch the edges of the processor, NEVER
touch the processor pins to avoid static discharge.

First take a moment to inspect your CPU for obvious damage due to shipping or handling.
Be sure that no noticeable damage exists before proceeding. You should have the following
items:

 1 AMD Athlon or AMD Duron processor.
 1 good heatsink and fan assembly.

Step 1

The following figure shows the processor socket. Note that the release lever on the
right side of the socket is down and latched. This position is used to lock the
processor in place. The lever must be raised to install the processor. To do this,
first push the lever sideways to unlatch it, then raise it all the way up
(approximately 90 degrees).

Step 2

The processor pin array at the top two corners is angled and has no pins in the corners.
Notice that at the top of the socket on the motherboard (near where it says "Socket 462")
the corners also do not have positions for pins. The processor must be positioned so the
pins match up properly. When you do that, the corner of processor that is cut off will be
positioned next to the release pivot.

K7MKLE System Board 15

It should take no force to install the processor, this is a zero insertion force (ZIF) socket. If
it takes any force you are doing something wrong. Check the pin alignment and also make
sure the release lever is raised up completely.
After placing the CPU lower the release lever to lock the processor in place.

Now with the processor properly installed, you can proceed to install the heatsink.
It is important to note that If you have never installed a heatsink on an AMD
Athlon or AMD Duron processor before it may be difficult. We recommend you
do a dry run a few times before doing the final installation. To allow you to do this
read the following instructions. Do not remove the film on the thermally
conductive compound until you are ready to do the final installation.

STOP

WARNING: Never run the processor without the heatsink properly

and firmly attached.

Step3

The picture below shows the bottom of the heatsink. Notice the step in the
heatsink surface, this portion fits over the top of the socket, where the legend
"Socket 462" is molded into the plastic. The heatsink must be mounted with this
step above the top of the socket or the heatsink will not be touching the processor
properly.

The next picture shows the removal of the plastic film from the thermally conductive
compound. The thermal compound is a thin layer of material that increases the efficiency of
the heatsink by filling microscopic surface voids in the processor or heatsink surface with a
thermally conductive material. Please do not remove the plastic film until you have
practiced installing the heatsink and mounting the clips on the socket. It can take a few tries
to get used to doing this.

K7MKLE System Board 16

The following picture shows a side view of the heatsink with the retaining clip at the
bottom of the heatsink. Make sure this retaining clip is at the bottom of the heatsink before
trying to install it.

The following picture shows the non-moveable end of the heatsink retaining clip installed
on the lug at the bottom of the processor socket. This end of the clip simply slides over the
lug when you tilt the heatsink / fan assembly towards the lug.
Now lock the locking clip for the retaining strap over the lug at the other (pivot end) of the
processor socket. This is an easy procedure after you do it a few times, but initially it will
require you to use a finger on one hand to push the latch down and use your other hand to
push the latch in. This is the part you need to practice to install the clip properly. When you
are holding the heatsink, make sure you do apply pressure to the fan. You could damage it
and cause thermal failure of the processor.

STOP

WARNING: Be careful not to scrape the motherboard during the mounting

of the fan or else damage may occur to the motherboard.

Now connect the wire from the heatsink fan to the CPU FAN connector on the motherboard.
This connector is keyed and can only be installed one way. If you use a heatsink assembly
that has two cooling fans, connect one to CPU FAN and the other to FAN1 . For more
information on the FAN connectors, refer to the FAN connector section later in this section.

STOP

WARNING: This main board supports ISM functions (please refer to

page 12 for more information), make sure you connect CPU heatsink
assembly to CPU FAN header. Otherwise, the main board will
malfunction.

CPU Technical Background

The CPU socket on your motherboard is known as Socket 462. This name was given to it
by AMD, it supports both the Duron™ and the AMD Athlon™ processors.

Athlon CPU

There are several types of Athlon CPUs, Model 1, 2 and 4. The principal difference
between the earlier Athlon Model 1 and Model 2 processors and the model 4 is the use of
256kB on-die cache, rather than 512kB of off-die cache. This allows the cache to run at the
clockspeed of the processor, rather than at a fraction (1/3, 2/5, 1/2) as in the earlier Athlons.
This constraint is the principal performance limit for the higher speed Athlon Model 2
processors. The use of on-die cache also allows the CPU to use a 0.05V lower core voltage
and a corresponding reduction in power consumption of approximately 10-20%. This
reduces the temperature of the processor.
There are two model 4 socket 462 CPUs, one using copper interconnects and the other
aluminium. The former is coloured blue and the latter green. The copper-based Athlon
CPUs run cooler than the aluminium versions.

Duron CPU

The Duron is AMDs low cost processor. It is very similar to the Athlon, using the same
Socket 462 interface. The principal difference between the Athlon and the Duron is in the
amount of full speed on-die L2 cache (64k rather than 256k) and a core voltage of 1.5v
rather than 1.7v to 1.8v, meaning a lower power consumption of just 22W. According to
tests it runs at about 90% of the performance of an Athlon of the same clock frequency and
at about 92-99% of the performance of an Athlon Model 1 or 2 of the same clock frequency.
It easily beats the same clock speed Intel Celeron processor and often out-classes even the
Pentium-III of the same specification.

The following gives a technical summary of the main CPU features:
System Bus:The processor system bus is the first x86 platform bus running at or above
200MHz. At present, AMD Athlon processors are available with 266MHz and 200MHz
system buses. As one of the fastest x86 processor buses currently available, the design
delivers as high as 100 percent more peak bandwidth than any x86 system bus.

Floating Point Engine: The AMD Athlon processor includes the first fully pipelined,
superscalar floating point engine for x86 platforms. The resulting floating point capability
is the most powerful ever delivered in an x86 processor.

K7MKLE System Board 19

Enhanced 3DNow!™ Technology: The first x86 instruction set to use superscalar SIMD
floating point techniques. Enhanced 3DNow! technology adds 24 instructions-19 to
improve MMX integer math calculations and enhance data movement for Internet
streaming applications and 5 DSP extensions for soft modem, soft ADSL, Dolby Digital,
and MP3 applications.

Cache Architecture: The AMD Athlon processor boasts a 384K total full-speed on-chip
system cache including 128K L1 cache--four times that of Intel's Pentium® III
processor--and 256K on-chip full-speed L2 cache.

K7MKLE System Board 20

2-4-2 CPU and System Cooling

Any attempt to operate the AMD Athlon™ Processor without a suitable cooling solution
will result in permanent damage to the processor and potentially other components within
the system.

Fan Headers

Your motherboard allows the use of in all 3 FANS. Of these 3 FANS, 1 can be used by the
CPU Heatsink assembly (Some heatsink assembly come with 1 FANs). The other 2 FAN
Headers allow connection of a Chassis Fan and a Power Supply FAN respectively. For a the
location of the FAN connectors, refer to the following picture:

The lay-out of all FAN Headers is the same, please refer to the picture below:
(Note: RPM sens only for FAN1 & FAN2)

Cooling Technical Background

As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems. Maintaining
the proper thermal environment is key to reliable, long-term system operation. The overall
goal in providing the proper thermal environment is keeping the processor module below
its specified maximum plate temperature.

Heatsinks induce improved processor heat dissipation through increased surface area
and concentrated airflow from attached fans. In addition, interface materials allow
effective transfers of heat from the processor to the heatsink. You can go the AMD
website (www.amd.com

) to find a list of AMD recommended FANs.

Note: If your case comes with a case FAN or a possibility to install a case FAN, we
recommend you use it.
