When you read this online manual and start to assemble your computer system, you may notice that some of the functions are marked as

“User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included many amazing and

powerful features, sometimes not every user is familiar with these powerful features. As a result of this we define features that can be

upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing additional devices. As for functions that

cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If need be, you can contact our local distributors or

resellers to purchase “Manufacture Upgrade Optional” components, and again you are also welcome to visit our official website at

What is Hyper-Threading?

Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in parallel within each processor resulting in increased utilization of processor execution resources. As a result, an average improvement of ~40% in CPU resource utilization yields higher processing throughput.

How Hyper-Threading Works

A form of simultaneous multi-threading technology (SMT), Hyper-Threading technology allows multiple threads of software applications to

be run simultaneously on one processor by duplicating the architectural state on each processor while the same processor execution resources is shared. The figure below represents how a Hyper-Threading based processor differentiates a traditional multiprocessor. The left-hand configuration shows a traditional multiprocessor system with two physical processors. Each processor has its own independent execution resources and architectural state. The right-hand configuration represents an Intel Hyper-Threading technology based processor. You can see that the architectural state for each processor is duplicated, while the execution resources is shared.

AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall

For multiprocessor-capable software

applications, the Hyper-Threading

based processor is considered two

separate logical processors on which

the software applications can run

without modification. Also, each logical

processor responds to interrupts

independently. The first logical

processor can track one software

thread, while the second logical

processor tracks another software

thread simultaneously. Because the

two threads share the same execution

resources, the second thread can use

resources that would be otherwise idle

if only one thread was executing. This

results in an increased utilization of the

execution resources within each

physical processor.

The figure below represents how Hyper-Threading saves time when it works. With two logical processors available on every single physical

processor, multi-threaded applications can now take advantage of thread-level parallelism on each physical processor for additional

performance. As software applications continue to be optimized to take greater advantage of processor parallelism, Hyper-Threading

technology provides an additional boost for newer capabilities and the growing needs of today’s users.

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To put

it in a simple way, DDR SDRAM is like data going along a two lane highway, while at the same time data in traditional SDRAM go along a

one way street. Therefore, it is a more advanced technology that provides a great overall improvement in system performance. DDR266

(PC2100) runs two times faster than the traditional PC133 SDRAM with the speed of Front Side Bus (FSB) up to 266MHz. (2x133=266).

And DDR333 (PC2700) is running at 333MHz FSB. Both PC2100 and PC2700 are a new naming standard for speed of DDR 266 and

DDR 333, representing their theoretical speeds of the RAM. The theoretical transfer rate of DDR 266 (PC2100) is 2.1GB/s and 2.7GB/s is

for DDR 333 (PC2700).

This motherboard supports ATA6 6, ATA100 or ATA133 IDE devices. Following table lists the transfer rate of IDE PIO and DMA modes. The IDE bus is 16-bit, which means every transfer is two bytes. As the hard drive industry introduces faster and higher capacity hard drives, the current Ultra ATA/100 interface causes a data bottleneck between the drive and the host computer. To avoid this problem, hard disk manufactures have introduced the new Ultra ATA-133 interface technology. percent increase in interface speed with transfer rate of 133MB/s. ATA/133 performance is ideal for new operating systems, such as Window XP, that demand more storage space and faster data transfer rates from more responsive computing experiences.

To make good use of this new technology and enjoy its best performance, we recommend you to pair your system with a hard disk equipped with ATA/133 technology so that your system's need for speed on this motherboard can be satisfied.

The Over Current Protection is a popular implementation on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU

uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection

useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3.3V/5V/12V

power supply provide the full line over-current protection.

Note: Although we have implemented protection circuit and tried to prevent any human operating

mistake, certain risks might still happen when CPU, memory, HDD or add-on cards installed on this

motherboard is damaged due to component failure, human operating error or other unknown natural

reasons. AOpen cannot guarantee that the protection circuit will always work perfectly.

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

The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or

when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and 2.140V. That is, the

transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only

143mv even when maximum 60A current is applied.

AC97 CODEC

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.

ACPI (Advanced Configuration & Power Interface)

ACPI is the power management specification of PC97 (1997). It intends to save more power by taking full control of power management to

operating system and bypass BIOS

Windows 98). This is a bit similar as the PnP

transition.

ACR (Advanced Communication Riser)

Building on the PC motherboard riser architecture, ACR slot is backward compatible with AMR but beyond the limitation of it. The ACR

specification is designed to support modem, audio, Local Area Network (LAN) and Digital Subscriber Line (DSL).

. The chipset or super I/O chip needs to provide standard register interface to operating system (such as

AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall

AGP (Accelerated Graphic Port)

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

the rapid developing of AGP card, we can see that it had been developed from single colorful AGP card to 2D and 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.

8X AGP, data transfer rate is 66MHz x 4byte x 8 = 2112MB/s.

AMR (Audio/Modem Riser)

The CODEC circuit of AC97 sound/modem solution can be put on motherboard or put on a riser card (AMR card) that connects to

motherboard through AMR connector.

ATA (AT Attachment)

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 been developed to 133MHz/Sec and would come out with fastest rate later (please refer to

AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall

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 /1 00 , data transfer rate is 16.6MHz x 6 = 100MB/s.

ATA /1 33 , 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.)

BIOS (Basic Input/Output System)

BIOS, is a set of assembly routine/program that reside in EPROM

devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required to access BIOS

without directly access hardware devices.

Bluetooth (a chipset) is to transfer information and voices at the frequency of ISM Band. Every Bluetooth technology devices do come with

a standard address for you to connect one-to-one or one-to-seven (to form a Pico-net), with transferring range up to 10 meters (100 meters

to follow), using low power radio. Bluetooth do not only possess high transfer rate of 1MB/s, it also could be encrypted with pin code. With

hopping rate of 1600 hops per second, it’s difficult to be intercepted and are less interrupted by electromagnetic wave.

The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home

networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs". The CNR specification is an open

industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft.

DDR (Double Data Rate) RAM

DDR RAM utilizes the existing SDRAM

available to systems in an easy to design and simple to adopt way. Based on FSB frequency, DDR RAM on the market are DDR200,

DDR266 and DDR333 with more coming around soon.

DDR200, transfer bandwidth up to 200x64/8=1600MB/s (PC1600)

DDR266, transfer bandwidth up to 266x64/8=2100MB/s (PC2100)

DDR333, transfer bandwidth up to 333x64/8=2700MB/s (PC2700)

DDR400, transfer bandwidth up to 400x64/8=3200MB/s (PC3200)

ECC (Error Checking and Correction)

The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special

algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only

detect single-bit error.

EEPROM (Electronic Erasable Programmable ROM)

Also known as E2PROM. Both EEPROM and Flash ROM can be re-programmed by electronic signals, but the interface technology is

different. Size of EEPROM is much smaller than flash ROM.

EPROM (Erasable Programmable ROM)

Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light. If BIOS has to be upgraded,

you need to remove EPROM from motherboard, clear by UV light, re-program, and then insert back.

EV6 Bus

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

FFCC--PPGGAA22 ((FFlliipp CChhiipp--PPiinn GGrriidd AArrrraayy))

After FC-PGA, FC-PGA2 is the package for 0.13µm process CPU developed by Intel, which can be plugged into SKT423/478 socket as

well.

Flash ROM

Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected

by virus. Because of increase of new functions, BIOS size is increased from 64KB to 512KB (4M bit).

Hyper Threading

Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in

parallel within each processor resulting in increased utilization of processor execution resources. As a result, an average improvement of

~40% in CPU resource utilization yields higher processing throughput.

IEEE 1394

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:

AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall

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).

Parity Bit

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.

PCI (Peripheral Component Interface) Bus

Developed by Intel, Peripheral Component Interconnect (PCI) is a local bus standard. A bus is a channel used to transfer data to (input) and

from (output) a computer and to or from a peripheral device. Most PCs have a PCI bus usually implemented at 32-bits providing a 33 MHz

clock speed with a throughput rate of 133 MBps.

PnP (Plug and Play)

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.

POST (Power-On Self Test)

The BIOS self-test procedure after power-on, sometimes, it is the first or the second screen shown on your monitor during system boot.

PSB (Processor System Bus) Clock

PSB Clock means the external bus clock of CPU.

CPU internal clock = CPU PSB Clock x CPU Clock Ratio

RDRAM (Rambus Dynamic Random Access Memory)

A DRAM technology developed by Rambus Corporation*, to achieve high speed of memory through the use of multiple channels in parallel

by 16-bits. Basically, RDRAM uses new structure of Multibank, which is quite different from FPM, EDO, SDRAM. Using different memory

module as well, RDRAM uses “RIMM” with transfer rate of 600/700/800MHz, providing bandwidth as high to 1.6GB.

RIMM (Rambus Inline Memory Module)

184-pin memory module that supports RDRAM

memory technology. A RIMM memory module may contain up to maximum of 16 RDRAM

AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall

devices.

SDRAM (Synchronous DRAM)

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.

SATA (Serial ATA)

The Serial ATA specification is designed to overcome speed limitations while enabling the storage interface to scale with the growing media

rate demands of PC platforms. Serial ATA is to replace parallel ATA

adding performance headroom for years to come. It is developed with data transfer rate of 150 Mbytes/second, and 300M/bs, 600M/bs to

come. It reduces voltage and pins count requirements and can be implemented with thin and easy to route cables.

SMBus (System Management Bus)

SMBus is also called I

set clock of clock generator for jumper-less motherboard. The data transfer rate of SMBus is only 100Kbit/s, it allows one host to

communicate with CPU and many masters and slaves to send/receive message.

SPD (Serial Presence Detect)

SPD is a small ROM or EEPROM

and chip parameters. SPD can be used by BIOS

C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC). For example,

device resided on the DIMM or RIMM. SPD stores memory module information such as DRAM timing

to decide best timing for this DIMM or RIMM.

USB 2.0 (Universal Serial Bus)

A Universal Serial Bus (USB) is an external bus (an interconnect) standard that supports data transfer rates of 12 Mbps. A single USB port

can be used to connect up to 127 peripheral devices, such as mouse, modems and keyboards. Introduced in 1996, USB has completed

replaced serial and parallel ports. It also supports plug-and-play installations and hot plugging Plug-and-play is the ability to add and

remove devices to a computer while the computer is running and have the operating system automatically recognize the change. USB 2.0,

which supports data transfer rates of 480 Mbps, has been widely used in motherboard these days.

VCM (Virtual Channel Memory)

NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory system’s ability to service

multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set of fast static

registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency and reduced power

consumption.
