When you read this online manual and start to assemble your computer system, you may find some of functions are called

“Manufacturer Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many

amazing and powerful features, in some situations, these powerful features are not used to every user. Hence, we changed

some key features as “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by

users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them

“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade

This motherboard supports AMD® Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into

CPU socket (with CPU Overheat Protection function implemented, the system will be automatically power off when the

temperature of CPU reached 97 degree, but works on AthlonXP CPU only).

1. Pull up the CPU socket lever and

up to 90-degree angle.

2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into the socket.

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the annoying problem of high CPU

operation temperature at the same time. In order to prevent accidental failure of CPU fan, which could cause the burning down

of the AthlonXP CPU, we, AOpen, have meticulously developed a new technology, named, O.H.P. (Overheat Protection)

Technology to protect them. Thanks to the intelligent monitoring design of AOpen O.H.P. technology, user can now finally set

their mind at ease even when fan failed to work without

fearing the possible damage of CPU.

Under the circumstances that CPU fan is running properly,

AthlonXP temperature should be way below the highest temperature limit of 97 ℃ . However, if CPU fan

accidentally becomes malfunction or improperly installed,

the CPU temperature would rocket abruptly, and you may

find your system hang up or crying over the smoking CPU

if you haven’t installed AOpen O.H.P. previously. With

AOpen O.H.P. technology applied, the specific thermal

detection pins on AthlonXP CPU would sense voltage

difference when processor is overheated with fan failed,

and the overheat protection system would immediately

send out a signal to abort your system by cutting CPU

electricity before any damage is done. Unlike other

manufacturers who use BIOS or software to control the

power supply of CPU, AOpen O.H.P. Technology is purely

hardware-controlled the minute after system boot-up, and occupies no system resource. We are pleasant to phase in this

practical function on all AOpen AMD series motherboards to protect customer’s valuable hardware and personal data.

make a total of four devices. In order to work together, the two devices on each channel must be set differently to Master and

Slave mode. Either one can be the hard disk or the CDROM. The setting as master or slave mode depends on the jumper on

your IDE device, so please refer to your hard disk and CDROM manual accordingly.

S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides impressive audio quality through optical fiber and allows you to enjoy digital audio instead of analog audio. Through a specific audio cable, you can connect the S/PDIF connector to other end of the S/PDIF audio module, which bears S/PDIF digital output. Normally there are two S/PDIF outputs as shown, one for RCA connector, the most common one used for consumer audio products, and the other for optical connector with better audio quality. Same as outputs, you can also connect RCA or optical audio products to input connectors on the module and have the voice or music come out from your computer. However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF digital input/output to connect to the S/PDIF digital input/output to make the most out of this function.

The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the

stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail

calculation.

Not only that, this motherboard implements 2200μF capacitor, which is much larger than normal capacitor (1000 or 1500μF)

and it provides better stability for CPU power.

VividBIOS deals with graphics and texts separately, and makes them running simultaneously during POST. With this innovative

design, VividBios now brings you a beautiful and sleek 256 colors screen without missing any important information shown on

In addition, the limited space of BIOS ROM is another big issue. When all of the traditional BIOS can only show

space-consuming and uncompressed Bitmap, AOpen has considerately tuned the BIOS to next generation, to recognize the

As the clock of CPU keeps rocketing higher and higher, it inevitably brings higher heat and

system temperature in a relative way. The way we deal with this heat problem, however, is to

spare no effort to add one fan after another to protect our pampered system, expecting these

fans could cool down our machine as much as it could.

But at the same time, we believe that same amount of users are affected terribly while working with their PC by the irritating

noises of these fans. As a matter of fact, we do not have to get our fans running at such a high speed in most cases; on the

contrary, we discovered that having your fans running at appropriate time and speed could not only reduce the noise, but also

consume the least power the system

needed, so as to prevent over-wasting

of energy resource.

Today, AOpen Motherboard is honored

to bring you a new overall solution,

SilentTek, to have your system quiet. To

collocate with hardware circuit, BIOS

and the utility under Windows,

SilentTek combined “Hardware-Status

Monitoring”, “Overheat Warning” and

“Fan Speed Control” with user-friendly

interfaces to provide you a perfect

balance between noises, system

performance and stability.

MMKK7799GG--NN // MMKK7799GG--11339944 OOnnlliinnee MMaannuuaal

The first image you have here is the Voltage Status page. You can find current status of all voltages and set your expected margins of warning level.

You may check your system voltage from the indicating bar here.

In “Temp/Fan/Case” page, you may get aware of the current temperature of CPU and the heat inside chassis, plus checking if fans are running properly.

Of course, you may set your defaulted lowest margin for your fans and the SilentTek would also pop up a message box and alarm you when the fan is rotating slower than this specified speed.

You may set the highest margin of your CPU and system temperature as default, and SilentTek would pop up a message box and alert you with alarm when the temperature goes beyond the specified margin.

MMKK7799GG--NN // MMKK7799GG--11339944 OOnnlliinnee MMaannuuaal

The following page is sure to be the most important part of this utility, you may control the rotation speed of specific fans you got

with options inside in this page. Respectively illustrate as follow:

1. Smart FAN Control: This is the default setting of

SilentTek and can be used for any branded computer

housing. With a special algorithm developed by

AOpen, the fan speed is automatically adjusted by

the factors of CPU and ambient temperature.

Ease-of-use and trouble free at your service.

2. Fixed FAN Control: Under this setting, a desired fan

speed is set fixed when operating.

3. Multiple Level Control: This is the most versatile

setting that allows you to set fan speed in relation to

temperature. You may find this setting fits youbest.

4. AOpen Recommend Setting: This setting is

designed specifically for AOpen housing. A series of

lab tests were conducted under the real world

scenario to determine optimum fan speed to reduce

noise level within CPU working condition and

temperature. Most of the time, the fan would remain

CD-ROM Rotation Speed Control: by enabling the CD-ROM

Rotation Speed Control, you can adjust the rotation speed of

your CD-ROM. When you set the speed to high level, the

CD-ROM will work at its fastest speed and it will run at basic

required speed while you set the value to low speed.

still when CPU is not fully utilized.

Note: Due to there are hundreds different brands of fan

on the market, there might be some inaccuracy

occurred when you have had adjusted your rotation

speed; this is still under criterion and please assured

that it won’t cause any problem to y our system.

AACC9977 CCOODDEECC

Basically, AC97 CODEC is the standard structure of PCI sound card. As we know, computer is digital-based, but music is based

on analog-based. Therefore, there must be a process to turn digital into analog during the last stage processing of sound in

computer. Hence, the component on sound card that play this important task is what we called CODEC.

Audio CODEC 97 (briefly called AC97) is the specification regulated by Intel, and it’s about the structure of audio conversion.

The special place about CODEC is that it is separated from sound card (CODEC is an independent chipset). Therefore, PCI

sound card could possess with 90db and do other application process as well. We called CODEC that meets this structure AC97

CODEC.

The main function of AGP simply put is to tell monitor what screen information had to be shown, a visual transmission device

3D graphic. AGP supports only memory read/write operation and single-master single-slave one-to-one only. Though AGP and

PCI share the same algorithm of 32-bit, its frequencies are 66MHz and 33MHz respectively. AGP interface had been

developed from 2X to 8x.

1X AGP, data transfer rate is 66MHz x 4byte x 1 = 264MB/s

2X AGP, data transfer rate is 66MHz x 4byte x 2 = 528MB/s

4X AGP, data transfer rate is 66MHz x 4byte x 4 = 1056MB/s.

specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to

133MHz/Sec and would come out with fastest rate later (please refer to Serial ATA).

DMA, data transfer rate is 16.6MHz/s.

Ultra DMA, data transfer rate is 16.6MHz x 2 = 33MB/s.

ATA/6 6, data transfer rate is 16.6MHz x 4 = 66MB/s.

ATA/100, data transfer rate is 16.6MHz x 6 = 100MB/s.

ATA/133, data transfer rate is 16.6MHz x 8 = 133MB/s.

(ATA/133 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 30ns.)

EEVV66 BBuus

EV6 Bus is the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock

edge to transfer data, similar as DDR RAM or ATA/66 IDE bus.

EV6 Bus Speed = CPU external bus clock x 2.

200 MHz EV6 bus, 200MHz = 100 MHz external bus clock x 2

IIEEEEEE 1133994

IEEE 1394, which also called Firewire, is a serial data transfer protocol and interconnection system. The main feature of the

Firewire that assures its adoption for the digital video and audio (A/V) consumer application is its low cost. Fire wire interface is

capable of supporting various high-end digital A/V applications, such as consumer A/V device control and signal routing, Digital

Video (DV) editing, home networking, and more than 32 channels of digital mixing. Gone are those days of expensive video

capture cards. Firewire allows for video capture from both newer DV camcorders with Firewire ports and older analog

equipment using A/V to Firewire converters.

The advantages of the IEEE1394:

High data transfer rate – Start from 400 Mbps, (with 800/1600/3200 Mbps coming soon), which is about 30 times faster than

USB 1.1.

Supports up to 63 devices (16 - daisy chained) with cable length up to about 4.5 m (14 feet).

Hot-pluggable (like USB). No need to turn of your device to connect or disconnect, and you don't need to reboot your PC. Also,

it is a plug-and-play bus.

IEEE1394 is very easy to connect (Like USB1.1/2/0).

PPaarriittyy BBiit

The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated,

parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the

parity error is occurred and this is called single bit error detection.

Oversimplified, Plug-and-Play automatically tells the software (device drivers) where to find various pieces of hardware (devices)

such as modems, network cards, sound cards, etc. Plug-and-Play's task is to match up physical devices with the software

(device drivers) that operates them and to establish channels of communication between each physical device and its driver.

SSDDRRAAMM ((SSyynncchhrroonnoouuss DDRRAAMM))

SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU host bus (EDO and FPM are

asynchronous and do not have clock signal). It is similar as PBSRAM to use burst mode transfer. SDRAM comes in 64-bit

168-pin DIMM and operates at 3.3V, and have been gradually replaced by DDR RAM.
