I have bought 3 or 4 of these boards to rebuild older systems. No problems out of any of them. If you need to put together a good cheap system.
Woos 7:05pm on Saturday, April 17th, 2010 
I got this board to replace a failing (and old) PCChips Socket A motherboard. Setup was fast and painless. Support for both kinds of RAM is good for those who wish to make an inexpensive upgrade.

Central Processing Unit: CPU
The mainboard supports AMD Athlon, Athlon XP and Duron processors in the 462 pin package. The mainboard uses a CPU socket called Socket-462 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not find the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.
CPU Core Speed Derivation Procedure
CPU Clock multipled by Core/Bus ratio equals the CPU core speed. For example: = 100MHz If CPU Clock Core/Bus ratio = 14 then CPU core speed = Host Clock x Core/Bus ratio = 100MHz x 14 = 1.4 GHz
Thermal Issue for CPU As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly crucial when building computer systems. Maintaining the proper WARNING! thermal environment is key to reliable operation. As such, the processor must be maintained in the specified thermal requirements. AMD recommends the use of high performance thermal interface material.

AMD Athlon/Duron processor with a speed of 600MHz and above requires LARGER heatsink and fan. You also need to add thermal grease between the CPU and heatsink to improve heat dissipation. Then, make sure that the CPU and heatsink are securely fastened and in good contact with each other. These are needed to prevent damaging the processor and ensuring reliable operation. You can check AMDs web site for more information.
CPU Installation Procedures for Socket 462
1. Please turn off the power and
unplug the power cord before installing the CPU.
2. Pull the lever sideways away

Sliding Plate

Open Lever

90 degree

from the socket. Make sure to raise the lever up to a 90degree angle. 3. Look for the gold arrow. The gold arrow should point towards the lever pivot. The CPU can only fit in the correct orientation. 4. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.
5. Press the CPU down firmly

Incorrect CPU placement (not at 90-degree angle) Gold arrow
into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Press down the CPU

Close Lever
Installing AMD Athlon CPU (Socket 462) Cooler Set
The following instructions will guide you through the heat sink installation procedures. Please consult your agent for the proper CPU cooler set.
1. Position your CPU cooler set onto the CPU. 2. Use one end of the clip to hook the latch of the CPU sliding plate.
Apply some heat sink paste
3. Hook the other latch to fix the cooling fan set. You may need a screw drive to press down the other side of the clip.
4. Connect the fan to the power supply connector provided on your mainboard.
MSI Reminds You. Please apply some heat sink paste on top of CPU to dissipate the heat more effectively.


The mainboard provides two 184-pin unbuffered PC2700/PC2100/ PC1600 DDR SDRAM or two 168-pin unbuffered PC100/133 SDRAM and supports the memory size up to 2GB. To operate properly, at least one DIMM module must be installed.
SDR DIMM Slots (DIMM 3~4)

DDR DIMM Slots (DIMM1~2)

MSI Reminds You. Make sure that you install only one type of memory modules (either SDR or DDR) at one time. DO NOT install both types at the same time. For security reason, the system will automatically power off if you simultaneously install SDR & DDR memory modules onboard.

DDR Module Combination

Fan Power Connectors: CPUFA1/SYSFA1
The CPUFA1 (processor fan) and SYSFA1 (system fan) support system cooling fan with +12V. They support three-pin head connector. When connecting the wire to the connectors, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control.


MSI Reminds You. 1. Always consult the vendors for proper CPU cooling fan. 2. CPUFA1 supports the fan control. You can install the PC Alert utility that will automatically control the CPU fan speed according to the actual CPU temperature.
Front Panel Connectors: JFP1 & JFP2
The mainboard provides two front panel connectors for electrical connection to the front panel switches and LEDs. JFP1 is compliant with Intel Front Panel I/O Connectivity Design Guide.

MSI Reminds You. If you dont want to connect to the front audio header, pins 5 & 6, 9 & 10 have to be jumpered in order to have signal output directed to the rear audio ports. Otherwise, the Line-Out connector on the back panel will not function.

FSB Mode Jumper: SW1

This jumper allows you to set the CPU FSB. When the system is down while doing the overclocking, you can use this jumper to set the CPU FSB that allows you to reset the system.
The motherboard provides one AGP slot and three 32-bit PCI bus slots.

AGP Slot PCI Slots

AGP (Accelerated Graphics Port) Slot (Optional)
The AGP slot allows you to insert the AGP graphics card. AGP is an interface specification designed for the throughput demands of 3D graphics. It introduces a 66MHz, 32-bit channel for the graphics controller to directly access main memory. The slot supports 4x/2x/1x AGP card.
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs. When adding or removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation for the expansion card to make any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are hardware lines over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT A# ~ INT D# pins as follows:
Order 1 PCI Slot 1 PCI Slot 2 PCI Slot 3 INT A# INT B# INT C# Order 2 INT B# INT C# INT D# Order 3 INT C# INT D# INT A# Order 4 INT D# INT A# INT B#

When set to Enabled, the system will remove (turn off) clocks from empty PCI/DIMM slots to minimize the electromagnetic interference (EMI). Setting options: Enabled, Disabled. Spread Spectrum When the motherboard clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clockspeed which may just cause your overclocked processor to lock up. Settings: Disabled, +/-0.25%, 0.37%, +/-0.50%, +/-0.75%. CPU Host/SDRAM/PCI Clock This item specifies the clock frequency of CPU host bus (FSB), SDRAM and PCI bus. It provides a method for end users to overclock the processor. If the item shows Default, the setting will use the default value for the clock frequency of CPU host bus, SDRAM and PCI bus. 3-28

Load Fail-Safe/Optimized Defaults
The two options on the main menu allow users to restore all of the BIOS settings to the default Fail-Safe or Optimized values. The Optimized Defaults are the default values set by the mainboard manufacturer specifically for optimal performance of the mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor for stable system performance. When you select Load Fail-Safe Defaults, a message as below appears:
Pressing Y loads the BIOS default values for the most stable, minimal system performance. When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default factory settings for optimal system performance.
Set Supervisor/User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to eight characters in length, and press <Enter>. The password typed now will replace any previously set password from CMOS memory. You will be prompted to confirm the password. Retype the password and press <Enter>. You may also press <Esc> to abort the selection and not enter a password. To clear a set password, just press <Enter> when you are prompted to enter the password. A message will show up confirming the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup without entering any password. When a password has been set, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration. Additionally, when a password is enabled, you can also have BIOS to request a password each time the system is booted. This would prevent unauthorized use of your computer. The setting to determine when the password prompt is required is the Security Option of the Advanced BIOS Feature menu. If the Security Option is set to System, the password is required both at boot and at entry to Setup. If set to Setup, password prompt only occurs when you try to enter Setup.
MSI Reminds You. About Supervisor Password & User Password: Supervisor password: Can enter and change the settings of the setup menu. User password: Can only enter but do not have the right to change the settings of the setup menu.
Using 4- or 6-Channel Audio Function
Appendix: Using 4- or 6-Channel Audio Function
The motherboard is equipped with Realtek ALC650 chip, which provides support for 6-channel audio output, including 2 Front, 2 Rear, 1 Center and 1 Subwoofer channel. ALC650 allows the board to attach 4 or 6 speakers for better surround sound effect. The section will tell you how to install and use 4-/6-channel audio function on the board.

A: We strongly recommend that you do NOT connect those described CPU fan directly to your motherboard, as it draws so much power, that it could damage it.

Try the BIOS boot recovery feature as described in 2. Try to clear the CMOS If problem still persists, ask your reseller for new BIOS chip or contact one of MSI office near your place for new BIOS chip http:// Q: Should I update my BIOS, once a new BIOS is released? A: A new BIOS is usually released due to the following reasons: 1. New function is supported 2. New BIOS source code
3. Bugs are found 4. Customer-specific request When we release a new BIOS, there's usually a release note attached which lists the reason for the release. Refer to this release note and decide for yourself if upgrading to the new BIOS will be worth it. A word of advice, though, do not upgrade to the new BIOS, unless you really have to. Q: How do I update the BIOS? A: Please refer to for details. Q: How do I identify the BIOS version? A: Upon boot-up, the 1st line appearing after the memory count is the BIOS version. It is usually in the format: 1. For older model number: AGwhere: 1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX (R). 2nd digit refers to the internal chipset code. 3rd digit refers to the processor class as 5 = 486, 7 = 586, 8 = 686. 4th digit is incremental. 091096 refers to the date this BIOS is released. 2. For newer model number: W5139MS V1.where: 1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX (R). 2nd - 5th digit refers to the model number. 6th - 7th digit refers to the customer as MS = all standard customers. V1.0 refers to the BIOS version. 091096 refers to the date this BIOS is released.

Q: After flashing the bios and rebooting the system, the screen went blank. A: For AMI BIOS Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM Insert this floppy disk in the floppy drive. Turn On the system and press and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file and recover the BIOS from the A drive. When 4 beeps are heard you may remove the floppy disk and restart the computer. For Award BIOS Make a bootable floopy disk Copy the Award flash utility & BIOS file to the said floppy disk Create an autoexec.bat with "awdfl535 biosfilename" in the content e.g. awdfl535 a619mj21.bin Boot up system with the said floppy (it will take less than 2 minutes before screen comes out) Re-flash the BIOS & reboot.


ACPI (Advanced Configuration & Power Interface) This power management specification enables the OS (operating system) to control the amount of power given to each device attached to the computer. Windows 98/98SE, Windows 2000 and Windows ME can fully support ACPI to allow users managing the system power flexibly. AGP (Accelerated Graphics Port) A new, high-speed graphics interface that based on PCI construction and designed especially for the throughput demands of 3-D graphics. AGP provides a direct channel (32-bit wide bus) between the display controller and main memory for high graphics quality and performance. Bluetooth Bluetooth refers to a worldwide standard for the wireless exchange of data between two devices. Bluetooth requires that a low-cost transceiver chip be included in each device. The tranceiver transmits and receives in a previously unused frequency band of 2.45 GHz that is available globally (with some variation of bandwidth in different countries). In addition to data, up to three voice channels are available. Each device has a unique 48bit address from the IEEE 802 standard. Connections can be point-to-point or multipoint. The maximum range is 10 meters. Data can be exchanged at a rate of 1 megabit per second (up to 2 Mbps in the second generation of the technology). BIOS (Basic Input/Output System) On PCs, an essential software that contains all the control code of input/output interface (such as keyboard, disk drives, etc.). It executes hardware test on booting the system, starts the OS, and provides an interface between the OS and the components. The BIOS is stored in a ROM chip. Bus A set of hardware lines within the computer system, through which the data is transferred among different components. In a PC, the term bus usually refers to a local bus that connects the internal components to the CPU and main memory. Cache A special memory subsystem that is used to speed up the data transfer. It stores the

MS-6738 Micro ATX Mainboard contents of frequently accessed RAM locations and the addresses where these data items are stored. Chipset A collection of integrated chips designed to perform one or more related functions. For example, a modem chipset contains all the primary circuits for transmitting and receiving data; a PC chipset provides the electronic interfaces between all subsystems. Clock Cycle Clock cycle (or tick) is the smallest unit of time recognized by a device. For personal computers, clock cycles generally refer to the main system clock, which runs at 66 MHz. This means that there are 66 million clock cycles per second. Since modern CPUs run much faster (up to 533 MHz), the CPU can execute several instructions in a single clock tick. CMOS (Complementary Metal-Oxide Semiconductor) CMOS is a widely used type of semiconductor, which features high speed and low power consumption. PCs usually contain a small amount of battery-powered CMOS memory to retain the date, time, and system setup parameters. DRAM (Dynamic RAM) A most common type of computer memory. It usually uses one transistor and a capacitor to represent a bit. As the development of technology, the memory type and specification used in computer becomes variety, such as SDRAM, DDR SDRAM, and RDRAM. For further instruction, please see the table below: Dynamic RAM (DRAM) Memory Technologies

ECC Memory (Error Correcting Code Memory) A type of memory that contains special circuitry for testing the accuracy of data and correcting the errors on the fly. EEPROM Acronym for Electrically Erasable Programmable Read-Only Memory. An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Also like other types of ROM, EEPROM is not as fast as RAM. EEPROM is similar to flash memory (sometimes called flash EEPROM). The principal difference is that EEPROM requires data to be written or erased one byte at a time whereas flash memory allows data to be written or erased in blocks. This makes flash memory faster. EIDE Short for Enhanced IDE, a newer version of the IDE mass storage device interface standard developed by Western Digital Corporation. It supports data rates of between 4 and 16.6 MBps, about three to four times faster than the old IDE standard. In addition, it can support mass storage devices of up to 8.4 gigabytes, whereas the old standard was limited to 528 MB. Because of its lower cost, enhanced EIDE has replaced SCSI in many areas. There are four EIDE modes defined. The most common is Mode 4, which supports transfer rates of 16.6 MBps. There is also a new mode, called ATA-3 or Ultra ATA, that supports transfer rates of 33 MBps. EISA (Extended Industry Standard Architecture) EISA is a standard bus (computer interconnection) architecture that extends the ISA standard to a 32-bit interface. It was developed in part as an open alternative to the proprietary Micro Channel Architecture (MCA) that IBM introduced in its PS/2 computers. EISA data transfer can reach a peak of 33 megabytes per second. ESCD (Extended System Configuration Data) It is a format for storing information about Plug-and-Play (PnP) devices in the BIOS. Windows and the BIOS access the ESCD area each time you re-boot your computer External Cache Short for Level 2 cache, cache memory that is external to the microprocessor. In general, L2 cache memory, also called the secondary cache, resides on a separate chip from the microprocessor chip. Although, more and more microprocessors are including L2 caches into their architectures.
