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 12

JP1: CPU DETECT

CONTROL

Set "ON "(default)--

Se t "OFF "- ­ NO RM AL

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 13

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 14

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 15

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

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: Be careful not to scrape the motherboard during the mounting

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

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 18

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 19

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

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

) to find a list of AMD recommended FANs.

VCRAM

Virtual Channel RAM is a technology that was initially developed by NEC. VCRAM
increases the memory bus efficiency and performance of the memory module by providing
a set of fast static registers between the memory core and I/O pins, resulting in reduced
data access latency and reduced power consumption. Each data request from a memory
master contains separate and unique characteristics. Multiple requests from multiple
memory masters can cause page trashing and bank conflicts, which result in low memory
bus efficiency. The VCRAM architecture assigns virtual channels to each memory master.
Since virtual channels maintain the individual characteristics of each memory master
request, bus efficiency is dramatically increased.

or software settings for your expansion card, such as jumpers.

 Remove the cover of your computer system case and the bracket plate on the slot you

intend to use. Retain the bracket for possible future use.

 Carefully align the card to the slot and press firmly.
 Now secure the card in the slot with the screw you removed.
 Replace the computer case cover.
 Set up the BIOS if necessary (This includes interrupts)
 Install the necessary software drivers for your expansion card.

If you run into problems with expansion cards this may be due to interrupt issues.

Wake-Up

WOL Technical Background

The Wake-On-LAN feature provides the capability to remotely power-on client systems
that support Wake-On-LAN by simply sending a Wake-On-LAN packet. After waking up
files can be uploaded to or downloaded from the client. With this feature, network
administrators can flexibly perform client maintenance during off-hours so that Total Cost
of Ownership (TCO) will be lower. Wake-On-LAN is a remote management tool with
advantages that can reduce system management workload, provide flexibility to the
system administrator's job, and of course save time-consuming efforts and costs.

Using Wake-On-LAN on your system requires a LAN adapter that supports the
Wake-On-LAN and software such as LDCM Rev 3.1x or later that can send and
receive wake-up packets.

2-8 Wake On Modem Header

The Wake On Modem Header is described under the PCI section because the WOM Header
can accept a cable from a PCI Modem Card that supports Wake On Modem (Also known as
Wake On Ring). For the pin lay-out of the WOL header, please refer to the picture below.

2-12 IDE 1 and IDE 2

The IDE connectors are used to connect IDE devices such as Harddisks and CD-ROM
drives to the motherboard. Each connector constitutes an IDE channel, each channel
accepts 2 IDE devices, one Master and one Slave. The IDE 1 connector is also known as
the primary channel, IDE 2 is the secondary channel. Therefore the primary Master is the
IDE device connected to IDE 1 as Master, the primary Slave is the IDE device connected to
IDE 1 as Slave. Jumpers on the IDE device determine Master and Slave settings. Your
harddisk or CD-ROM should have a sticker with jumper settings. Make sure that you set
these jumpers correct. Please use the following advise as reference:

 If you have only device connected to an IDE connector, always set it as Master.
 If you have one HDD and CD-ROM in your system, then connect the HDD to IDE 1

as Master, and the CD-ROM to IDE 2 as Master.

 If you have one Harddisk and one CD-ROM connected to the same IDE connector,

set the HDD to Master and the CD-ROM to Slave.

Ultra DMA

This motherboard supports Ultra DMA 66 IDE devices, if your southbridge is the 82C686B
it will even support Ultra DMA 100. If the UDMA mode for the IDE channels are set to
auto in the BIOS the motherboard will use the fastets possible interface to comminucate
with your IDE devices. (Note however that windows may not support UDMA 100 yet, see
the FAQ chapter)
For the location of the IDE connectors, refer to the following picture:

K7MKLE System Board 31

2-13 FDD1 (Floppy Disk)

The floppy disk connector allows connection of a floppy drive. In all two floppy drives can
be connected to the motherboard, known as floppy A and B. The BIOS allows you to
disable the floppy controller if you do not use any floppy drives, that will free an Interrupt.
The BIOS also allows swapping of floppy A and B although this will not be useful to most
users. For the floppy disk connector location, refer to the following picture:

2-14 PWR1 (ATX power supply)

The ATX power supply connector is where your power supply plug must be inserted. Note
that this motherboard only supports ATX style power supplies, AT style power supplies are
not supported. Note the following:
 We recommend use of at least a 250W power supply, if you use a very fast CPU (>

900MHz) and have many peripheral devices we recommend use of a 300W power
supply. Do not save on the power supply, it feeds the whole system.

 If you use WOL and WOM, make sure that power supply can support at least 720mA

on the 5V standby line. Anything LESS is unacceptable. Even better, get a 1A 5V
standby power supply.

Descriptions of each individual connector follow:

 PW-LED

The Power LED connector allows you to connect a three pin LED from the case. Notice the
polarity, LEDs will only light up if the polarity is correct.

 PW-ON

The Power ON connector is to be used with the push-button power switch in the case. This
push button should be a momentarily contact type switch (that is, it should not lock in the
ON state but flip back OFF as soon as you release it). All ATX cases come with such a
switch. The BIOS allows you to select the power down mode. Either power down
immediately on a button push, or with a 4 second delay.

 Speaker

The speaker connector is for the internal case speaker. This speaker will enable the BIOS to
give spoken messages in case of boot up trouble. The BIOS beep codes also use this
speaker. For Games and Music this speaker will not be used, but rather the back panel
line-out connector.

 Reset

The reset connector is for connection of the reset switch. This switch, when pressed, will
immediately reset the system (that is, no matter what you where doing, the system will
restart. This is very similar to powering to system off and then on again). Note that
Windows, Linux and other operating systems do not appreciate the use of the reset switch.
When you are working under windows, always use the shutdown feature under the start
button (Yes, very logical).

K7MKLE System Board 34

 HDD LED

This LED will light up whenever one of your IDE devices is being accessed. Usually this
will be a harddisk, as such the name HDD LED.

 TB-LED

This is the Turbo LED, this LED is always on and is similar in function to the Power LED.

 Ext-SMI

This is the External System Management Interrupt Button connector. Connect the second
button on your ATX case to this connector. Pressing that button will force the system into
suspend mode. (The BIOS allows specifying of the suspend state, and of the wake-up
events that can wake the system up again).

Chapter4 The BIOS

The BIOS is a piece of software (Basic Input Output System) that performs most low level
tasks. When you start up your system, the BIOS is the first code that gets to run. The BIOS
resides in a FLASH ROM, and the code in the FLASH ROM can be updated through a
special utility called AWDFLASH. (Award Flash). This is generally not necessary, but in
some cases updating the BIOS is necessary to support new devices that were not on the
market at the time the motherboard was released. For the physical location of the BIOS
FLASH ROM IC on your motherboard, refer to the picture below:

BIOS

The BIOS IC is inserted in an IC socket, which means that it can be removed and
exchanged for another IC if necessary.

Is updating my BIOS necessary?

As a general rule if your system is functioning properly and you are not an experienced user,
do not try to update the BIOS. Only if you have specific problems that a BIOS update may
solve may it be advisable to update the BIOS.
The update process is pretty complex, and you should bear in mind that if updating the
BIOS goes wrong you may render your system unbootable. Therefore, do not update unless
you know what you are doing.

Finding the latest official BIOS revision

For the latest official BIOS revision, please go to our website at www.lucky-star.com.tw
On the support page you can find the latest BIOS files for our motherboards.

.

K7MKLE System Board 38

4-1 Updating the BIOS

As said, this procedure is complicated, ONLY update your BIOS when you experience

problems with your system. Because each BIOS release completely overwrites the previous
version and there is no need to update to intermediate BIOS releases when updating the
BIOS. Therefore always use the latest BIOS revision when doing a BIOS update. The BIOS
update procedure is as follows:

 In order to flash update the BIOS, you will need 2 files:

The BIOS binary file (.bin file from the website)
AWDFLASH.EXE utility file. (This utility can be downloaded from our website)

 Create a directory on your C harddisk drive: and name it FLASH
 Put the BIOS .bin file and the AWDFLASH utility in the FLASH directory.

You may want to jot the BIOS .bin file name down on a piece of paper.

 Restart the computer, press DEL to go into the BIOS, then please disable the

following:
System BIOS Cacheable (in Advanced Chipset Features)
Video BIOS Shadow (in Advanced BIOS Features)
Save the changes by selecting ‘save and exit’, and restart the computer.

 Press Ctrl + F5 just before Windows is starting up (right after the second BIOS screen)

for a DOS boot, you will see the message "Windows is bypassing all your startup

files". You end up at a DOS prompt.

 Now type cd FLASH to change to the newly created directory.
 Here type AWDFLASH mybios.bin /py /cc /sn /cd, where mybios.bin is the file name

for the BIOS binary file you want your BIOS to upgrade to. Now the upgrading will

begin.

WARNING:

STOP

 After the upgrading has ended press F1 to reset, press DEL to go into BIOS and make

Load Setup Defaults.
Go into the Frequency/Voltage Control page to adjust your CPU speed and voltage
(please make sure the CPU voltage matches your CPU specs, in case of doubts leave it
to ‘default’).

Save your settings and you are done.

Do NOT in any way disturb the system during upgrading. If for any
reason the system is stalled your system may not be able to boot
again.

the following changes:

K7MKLE System Board 39

4-2 The CMOS memory

The BIOS uses the CMOS memory to store all the settings that have been made
through the BIOS Setup pages.

Battery

The CMOS memory remembers all settings, even when the system is switched off,
by use of a 3V Lithium battery. If this battery runs low CMOS is unable to keep its
settings and you will need to replace the battery. The BIOS will give you an error
message wgen it detects a low battery voltage. The error message ‘CMOS
checksum error’ may also point to a low battery problem.

Restoring default settings

You can load default values into the CMOS memory by selecting ‘Load
Optimized Defaults’ in the BIOS Setup. If you need to force the CMOS settings to
default without entering the BIOS Setup page you can use the JBAT1 jumper. For
the location of the jumper and the battery, refer to the following picture:

Battery

JBAT1

Normally JBAT1 will be in the 1-2 position, this will connect the battery to the
southbridge of the chipset which contains the CMOS memory. If JBAT1 is
temporarily set to 2-3 this will interrupt the battery electricity flow, and the CMOS
memory will be erased, this will however only work if the power supply is not
switched on. Now at the next reboot the BIOS will automatically load the CMOS
default values.

K7MKLE System Board 40

Take the following steps to clear CMOS memory:

 Take the power cord from the power supply.
 Temporarily set JBAT1 to 2 – 3, and set it back to 1 – 2.
 Put the power cord back and restart the system, the default values will be

loaded.

Boot Devices

The first to third boot device items allow you to select what device the system should boot
from. If the BIOS fails to boot from the first boot device, it will attempt to boot from the
second boot device, if that fails too, the third boot device is tried. If you set the boot other
device item to enabled, the BIOS will try to boot from other devices if the first to third
choices all fail. If you set this item to disabled, the BIOS will not boot if the first to third
devices all fail to boot.
The list you can choose from for the first to third device is the same, refer to the table

4-3-9 Passwords

The BIOS Setup program allows you to specify passwords in the Main menu. The
passwords control access to the BIOS during system startup. The passwords are not case
sensitive. In other words, it makes no difference whether you enter a password using upper
or lowercase letters. The BIOS Setup program allows you to specify two separate
passwords:

 Supervisor password
 User password.

The function of the supervisor password depends on the setting for the Security Option
item on the Advanced BIOS Features page. If set to System, the supervisor password must
be given every time the system boots, if set to setup, the password must be given only when
you want to enter the BIOS Setup.
The user password has the same functionality, with the only difference that anybody
logging in with the user password may only change the user password when entering the
BIOS Setup page. All other items in the BIOS Setup will be disabled (unchangeable).
When both passwords are disabled, anyone may access all BIOS Setup program functions.

Setting the password

To set the Supervisor password, select the Set Supervisor Password item in the main BIOS
Setup Menu. Now a dialog will pop up asking you to enter a password.

Chapter 5 Frequently Asked Questions

5-1 Boot Issues

AWARD BIOS Beep Codes

In case of errors the AWARD BIOS will send beeps to the system speaker. Although the
spoken error messages replace the beep codes, it may still be convenient to know what the
beep codes mean.

Beeps Meaning

No beep at all This means your motherboard is dead, either due to a defective or

underrated power supply, poorly seated CPU or RAM, or a

Dead-On-Arrival (DOA) board.
One beep The board is working fine.
Long-short-short This means no video card detected (or a poorly seated video card)
Repeated single tone This is a memory problem (could be the DIMM, the memory

controller or the internal CPU cache memory).
two-tone siren Generally caused by overheating or out of specification voltages.
Rapid beeps this means a key is stuck on your keyboard, it is not properly

plugged in, or the keyboard is incompatible in some way
The AWARD BIOS offers no other codes, any other error messages are displayed on the
screen. (As explained above)

Below you will find a list of other possible causes of boot problems. Please go through
them one by one to find the source of your boot problem if the methods described above
did not help you.

AGP Speed setting

If AGPx4 is enabled in the BIOS (Advanced Chipset Features page) and you do not use
AGP card, or your AGP graphics card that doesn't support 4x mode? disable it in those
cases

USB devices

The board may fail to start the memory check during the boot sequence, this may be related
to a USB device (such as a scanner) attached to the system. Try disconnecting all USB
devices from the system.

K7MKLE System Board 75

Proper insertion of the CPU and other parts

If the board does not boot up at all but the FANs are working it may be that the CPU is
incorrectly seated in the motherboard. Also, if using an AGP graphics card, verify that it is
seated correctly. Try without the AGP card screwed into the case, this can sometimes cause
the AGP card to rest in the slot at an angle. Also try reseating your DIMMs (Press them into
their sockets firmly, but do not apply too much force)

My machine does not boot, FANs turn on, but the floppy light just stays on

Your floppy disk cable may be connected the wrong way round. Try reversing it. If this
doesn't help check the floppy drive ribbon cable. At one end of the cable, seven of the
strands should be split and twisted compared with the rest of the ribbon. If not, and your
cable is completely flat throughout, then you need to get a ribbon cable with a "twist" in.

5-2 System Cooling

In older computer systems cooling was not a big issue. But with CPU speed constantly
increasing improper cooling of the system as a whole can lead to hard to trace problems.
This motherboard E comes with 3 FAN Headers, make use of them!
The following is an excerpt from a warning AMD released on this issue:

The new PGA (Pin Grid Array) AMD Athlon(tm) and AMD Duron(tm)
processors have very different thermal specifications from any preceding AMD
processor. Due to these differences, the AMD Athlon and AMD Duron processors
should NEVER be run without a heatsink, 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
heatsink installed may be common industry practice, it should never be
attempted with the new PGA AMD Athlon and AMD Duron processors...
Additionally, the new exposed flip-chip design of the PGA AMD Athlon and
AMD Duron processors requires a clip load between 12 and 24 pounds (typically
16 pounds), a load that may not be met by most older heatsink designs. A thermal
compound, such a thermal grease or phase-change material, must ALWAYS be
applied between the processor and heatsink as well. Typically, AMD
recommended heatsinks that include the thermal compound. If the thermal
compound must be purchased separately, a list of suggested compounds can be
found in the 'AMD Thermal, Mechanical, and Chassis Cooling Design Guide'.
Refer to the AMD website.

K7MKLE System Board 77

5-2-1 Suitable Socket A CPU coolers

AMD maintains a list of approved thermal solutions for the Athlon processor.
Please do NOT use Pentium heatsinks, Duron processors may crack when trying
to force Pentium heatsinks and fans onto them. The processors have slightly
different sizes so this is not a good idea. Make sure the cooler is approved for
Socket A use.

In addition Duron processors come with four little "feet" on top of the processor, do not buy
a cooler which also has these feet (or remove them if it does). Eight feet are bad news,
since the cooler won't make proper contact with the CPU and it may get damaged. Please
refer to the AMD website at www.amd.com
strongly recommend that you use only FANs found there.

Why is my CPU running so hot?

If your CPU temperature is over 70 degrees C you have a cooling problem. By far the most
common cause of this is the improper removal of the protective square over the pre-applied
thermal paste. (See the hardware installation CPU section). For the adventurous, you may
remove the original thermal paste layer by using a solvent (such as oil free nail varnish
remover), and apply a standard thermal conducting compound or Artic Silver instead. Make
sure that the thermal contact between CPU and Heatsink is OK.

Take care in connecting the heatsink to the CPU

Note that the CPU core (the little raised green rectangle on the CPU) is very fragile. It is
very important to not use any horizontal force or any rocking motions when installing a
CPU FAN. The heatsink can grind the corners and edges off of the CPU incredibly easily.
It's fairly loud when it happens, Dealers will generally refuse a refund when you damage
your CPU like this therefore be CAREFULL.

Normal CPU temperature readings

The temperature of your CPU depends upon its speed in MHz, the core voltage, your CPU
FAN, the movement of air through your case and the ambient air temperature. However, a
typical CPU temperature (not overclocked) as measured by the on board thermister should
be around 40-50 degrees Celcius. The case temperature should be approximately 5-10
degrees above room temperature (or less). Do not worry if your figures are slightly higher
than these, but you should begin to think about improved cooling if your CPU temperature
is 50 degrees C or higher. The maximum temperature is 90 degrees C according to AMD,
but your processor is very unlikely to be stable at temperatures near this! Also, processor
life is directly related to temperature.

Maximum FAN Current and Wattage

The maximum current that the FAN headers on this board can provide is 0.5A. Because
Wattage = Voltage x Current ( I ), this means that at 12V the wattage the K7MKLE can
support on each header is 6W.

5-3 Video Issues

Setting AGP speed

In the BIOS setup on the Advanced Chipset Features page you can set the AGP 4X mode
item to either enabled or disabled. It is not possible to select between AGPx1 and AGPx2
using the BIOS, this is selected automatically depending on the AGP card you use.
If you use a Creative graphics card the AGP speed can be selected using Creative's
agpwizard which is available for download at www.creative.com. Note that this utility will
not work with non-Creative graphics cards.

determining AGP speed

To determine the AGP speed, a utility such as WCPUID (available under downloads at
http://www.h-oda.com) can be used.

Setting the AGP aperture

The AGP aperture is the official name for the stretch of main memory that is reserved for
AGP. The size of the aperture can be set through the BIOS setup. Go to the Advanced
Chipset Features page and use the AGP Aperture size item to set the size. It is advisable to
set the AGP aperture to half the system RAM - i.e. set to 32MB with 64MB of RAM. The
default value is 128MB, which is best set back if you have less then 256MB of memory.

AGP driving control explained

The manual hex range (00h-FFh) allows the user to set the timing of the signal that the
video card driver uses to communicate over the AGP bus. Default for the AGP Driving
control is 'Auto', this is the lowest-common denominator settings that provides the widest
compatibility.

As for how to find out the specific settings recommended for various video cards, the best
recommendation would be to contact your video card vendor first (attempting to contact the
chipset provider as well may be advisable). Ask them what their recommended manual
timing is.

5-4 Memory Issues

Memory related BIOS settings

Depending on the type and speed of your SDRAM memory settings will be different.
Below two types of settings will be given, one optimized for speed, and one optimized for
stability. If your system is unstable with the speed-optimized settings, try increasing the IO
voltage one step. (This will have your system run out of specs, we recommend you use the
settings optimized for stability instead). Moving the DIMM module to another DIMM slot
may sometimes help as well. You should normally place your first SDRAM module in
DIMM2, the next in DIMM1. DIMM2 is furthest from the processor.

Settings optimized for speed

BIOS Page Item Setting
Advanced Chipset Features DRAM timing by SPD Disabled
Advanced Chipset Features DRAM Clock 100MHz for PC-100

133MHz for PC-133

Advanced Chipset Features SDRAM Cycle length 2 for CAS 2 PC133 SDRAM

3 for PC100 SDRAM, most
unbranded PC133 SDRAM and

PC133 CAS 3 SDRAM
Advanced Chipset Features Bank Interleave 4 bank
Advanced Chipset Features Fast R-W Turn Around Enabled

Settings optimized for stability

If your machine is experiencing stability problems and you suspect your SDRAM is the
cause of the problem, you will need to set the SDRAM on its most conservative settings.
First try:

BIOS Page Item Setting
Advanced Chipset Features DRAM timing by SPD Enabled
This will force the system to use the timing as specified in the SPD EPROM on the
SDRAM module. If this does not work, use the following conservative settings:

Advanced Chipset Features DRAM timing by SPD Disabled
Advanced Chipset Features DRAM Clock 100MHz
Advanced Chipset Features SDRAM Cycle length

Advanced Chipset Features Fast R-W Turn Around Disabled

Typical signs of SDRAM instability include failure to pass the Power On Self Test (POST)
when booting, frequent error messages from Windows describing Page Faults or other
system errors and random freezes of the machine requiring a reset.

Support of DDR SDRAM

This motherboard is unable to support DDR (Double Data Rate) SDRAM due to limitations
of the VIA Apollo KT133A chipset.

Support of ECC SDRAM

This motherboard is unable to support ECC (Error Correcting) SDRAM due to limitations
