When you read this online manual and start to assemble your computer system, you may find some of functions are called “Optional”, and some are called “Upgrade Optional”. Though all AOpen motherboards include many amazing and powerful fea tures, in some situations, these powerful features are not used to every user. Hence, we changed some key features as “Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them “Optional”. If needed, you can contact our local distributors or resellers for purchasing “Upgrade Optional” components, and again you can visit AOpen official web site: english.aopen.com.tw

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 bur ning down of the Athl onXP 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.

For computer system, all components run with their fixed working frequencies; and all kinds of peripheral components frequencies run interactively with CPU system frequency in a regular basis. Overclocking, a must-do-thing preferred by people these days, is done basically by manually adjusting CPU FSB up above its standard rate through BIOS. AOpen provide sets of AGP/PCI frequencies for overclockers to manually overclock AGP/PCI frequency while taking care of the system stability at the same time. AGP/PCI and CPU FSB will function asynchronously. The available range of AGP frequency is from 66MHz to 96MHz and 33MHz to 48MHz for PCI frequency. With this solution given, there would be no hassle from AGP/PCI overclocking, and thus PCI frequency would no longer be the headache of overclocking anymore. Moreover, we provide sets of adjustable voltage setting of AGP card from 1.5V, 1.53V, 1.56V and 1.6V in BIOS.

Note：AGP frequency= PCI frequency X 2. The onboard sound device could be malfunction if PCI frequency is set too high.

Note:

The design of this product follows CPU and chipset vendor's design guideline. Any attempts to push beyond product specification are not recommended and you are taking your own risk to damage your system or important data. Before doing overclocking, you must make sure your components are able to tolerate such abnormal setting, especially CPU, DDR RAM, hard disks, and AGP cards.

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 they could. But at the same time, we believe that same users are affected terribly by the irritating noises of these fans while working with

their PC. 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 not only reduces the noise, but also consumes the least power the system needs, so as to prevent over-wasting of energy resource.

Today, AOpen Motherboard is honored to bring you a new overall solution, SilentTek, to make 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 among noises, system performance and stability.

AAKK7766FF--440000NN OOnnlliinnee MMaannuuaall

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.

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.

AAKK7766FF--440000NN OOnnlliinnee MMaannuuaall

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 this utility and also the most easy-to-set one, which can be applied to any housing. It can automatically adjust the fan speed by exerting algorithm similar to “Fuzzy Logic”. All you got to do is to set the margin of the temperature, and then SilentPC would judge automatically for your system, lifting or lowering the rotation speed.

2. Fix FAN Control: In this setting, you may set a fixed rotation speed for each fan you installed.

3. Multiple Control: This is the most unconstrained setting, which allows you to be on top of all details and set different rotation speed for different temperature.

4. AOpen Recommend Setting: This is the best setting to fit in with AOpen housing; SilentPC would keep your system under the least quiet situation, and would only lift the fan rotation speed for heat-dissipation when necessary. According to our practical testing, we found

Note: Due to the re 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 your system.

that in most cases, the fan would remain still when the CPU is not in full loading.

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.

Before talking about ATA (AT Attachment), we must understand DMA (Direct Memory Access), which allows devices to skip the CPU devices and access memory directly. DMA specification could not only eliminate the workload of CPU, but also accelerate the transmission of data. DMA begins with a data transfer rate of 16.6MB/Sec, but afterward developed to new data rate of 33.3MB/Sec, which is twice the data rate and we called it Ultra DMA. ATA details power and data signals between the drive and integrated drive controller and the computer's motherboard. Two drives (master and slave) are supported. The ATA specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had be en developed to 133MHz/Sec and would come out with fastest rate later (please refer to
