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.
24
AAXX44GGEE TTuubbee--GG // AAXX44PPEE TTuubbee--GG OOnnlliinnee MMaannuuaal
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.

Although Intel claims that 845GE/PE Chipsets only support two DIMM sockets (four banks), we overcome this obstacle with special circuit
design in order to provide better adaptability for different combinations of various RAM modules. On this motherboard, DIMM1 occupies
the 1st and 2nd banks; both DIMM2 and DIMM3 are designed to share the 3rd and 4th banks. Thus, maximally you can insert one double
side RAM module on DIMM2 or DIMM3, or insert one single side module on both DIMM2 and DIMM3 the most. After our testing and
verifying, the following configurations are approved to be running properly.

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To p u t
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).

Do you enjoy listening baseball live broadcast while playing your PC at the same time? Though you can connect few designated
broadcasting channels through some small broadcasting utilities on your PC, there are always abominable problems such as the on and off
listening quality, limitation of audience numbers and the long hours of connection to the broadcasting server. To solve the above hassles for
our users, AOpen integrates the FM frequency radio function into a small piece of expansion card to allow you enjoy the exciting game
broadcasts without missing any good moments. Even more, you can tape down any exciting pitch for later replay. To preserve the original
sound of your programs, you can convert the .WAV format file into .MP3 file for the long term keeping. Besides, setting up to 10 of your
favorite channels is as easy as normal radios. To be more considerate for our users, you may use JukeBox FM, integrated in our BIOS, to
listen to radio without entering operation system after installing this FM Radio Expansion card. It’s never been easier with FM Radio!
Installing FM Radio Card:
Please unplug your power cord before processing the following steps.
1. Unpack your FM Radio Card from the box 2. Connect the signal cable of the FM Radio Card to the FM header onboard

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
CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation.
Not only that, AX4GE Tube-G / AX4PE Tube-G implements 2200μF capacitors, which is much larger than normal capacitor (1000 & 1500
μF) and it provides better stability for CPU power.

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.

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.

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 you
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.
lso, you can check if fans are running properly.
Of course, you may set you
defaulted lowest margin fo
your fans and SilentTek would
also pop up a message box to
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 to alert
you with alarm when the
temperature goes beyond the
specified margin.

The following page is surely the most important part of this utility. You may control the rotation speed of specific fans that you have got the
options inside in this page.
1. Smart FAN Control: This is the default setting o
SilentTek and can be used for any branded compute
housing. With a special algorithm developed by AOpen,
the fan speed is automatically adjusted by the factors o
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 that this setting fits you best.
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
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.

fan would remain still when CPU is not fully utilized.
Note: Due to hundreds different brands of fan on the
market, inaccuracy may happen in some cases when you
had your rotation speed adjusted. It is still under the
criterion and please rest assured that it won’t cause any
roblem to your system.

AACC9977
Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CODEC for analogy I/O they are linked by
AC97 link bus. Since digital processor can be put into motherboard main chipset, the cost of sound/modem onboard solution can be
reduced.
AACCPPII ((AAddvvaanncceedd CCoonnffiigguurraattiioonn && PPoowweerr IInntteerrffaaccee))
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.
AAGGPP ((AAcccceelleerraatteedd GGrraapphhiicc PPoorrtt))
AGP is a bus interface targeted for high-performance 3D graphic. AGP supports only memory read/write operation and single-master
single-slave one-to-one only. AGP uses both rising and falling edge of the 66MHz clock, for 2X AGP, the data transfer rate is 66MHz x 4byte
x 2 = 528MB/s. AGP is now moving to 4X mode, 66MHz x 4byte x 4 = 1056MB/s. AOpen is the first company to support 4X AGP
motherboards by both AX6C (Intel 820) and MX64/AX64 (VIA 694x), started from Oct 1999.
. The chipset or super I/O chip needs to provide standard register interface to operating system (such as
register interface. ACPI defines ATX momentary soft power switch to control the power state

AAPPMM ((AAddvvaanncceedd PPoowweerr MMaannaaggeemmeenntt))
Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power
management.
AATTAA ((AATT AAttttaacchhmmeenntt))
ATA is the specification of diskette interface. In 80’s, many software and hardware manufacturers instituted the ATA specification together.
The AT is meaning International Business Machines Corporation (IBM) personal computer/AT’s bus structure.
AATTAA//6666
ATA/66 uses both rising edge and falling edge but doubles UDMA/33 transfer rate. The data transfer rate is 4 times of the PIO mode 4 or
DMA mode 2, 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66 IDE cable.

AAXX44GGEE TTuubbee--GG // AAXX44PPEE TTuubbee--GG OOnnlliinnee MMaannuuaal
l
AATTAA//110000
ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is
reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same
as ATA/66.
AATTAA//113333
Compared to traditional ATA/100, ATA/133 has been up to 33 percent increase in interface speed with transfer rate of 133MB/s. ATA/1 33
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.
BBIIOOSS ((BBaassiicc IInnppuutt//OOuuttppuutt SSyysstteemm))
BIOS is a set of assembly routine/program that reside in EPROM or Flash ROM. BIOS controls Input/output devices and other hardware
devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required to access BIOS
without directly access hardware devices.
BBuuss MMaasstteerr IIDDEE ((DDMMAA mmooddee))
The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for the
mechanical events. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without interrupting CPU,
and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need the bus master IDE driver
and the bus master IDE HDD to support bus master IDE mode.

CCNNRR ((CCoommmmuunniiccaattiioonn aanndd NNeettwwoorrkkiinngg RRiisseerr))
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.
CCOODDEECC ((CCooddiinngg aanndd DDeeccooddiinngg))
Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97
sound/modem solution.
DDDDRR ((DDoouubbllee DDaattaa RRaatteedd)) SSDDRRAAMM
DDR SDRAM utilizes the existing DRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an
easy to design and simple to adopt way. Initially a perfect solution for memory intensive server and workstation applications, DDR low cost
and low voltage will ultimately make it an ideal solution for all segments of the PC market, high performance desktop and mobile PCs,
Value PCs and even Internet Appliances and mobile devices.
DDIIMMMM ((DDuuaall IInn LLiinnee MMeemmoorryy MMoodduullee))
DIMM socket has total 168-pin and supports 64-bit data. It can be single or double side, the golden finger signals on each side of PCB are
different, and that is why it was called Dual In Line. Almost all DIMMs are made by SDRAM
DIMMs are made by FPM/EDO
and only operate at 5V. Do not confuse them with SDRAM DIMM.

Channel for communications between the memory and surrounding devices.
EECCCC ((EErrrroorr CChheecckkiinngg aanndd CCoorrrreeccttiioonn))
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.
EEDDOO ((EExxtteennddeedd DDaattaa OOuuttppuutt)) MMeemmoorryy
The EDO DRAM technology is actually very similar to FPM (Fast Page Mode). Unlike traditional FPM that tri-states the memory output data
to start the pre-charge activity, EDO DRAM holds the memory data valid until the next memory access cycle, that is similar to pipeline effect
and reduces one clock state.
EEEEPPRROOMM ((EElleeccttrroonniicc EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))
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.
EEPPRROOMM ((EErraassaabbllee PPrrooggrraammmmaabbllee RROOMM))
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.

EEVV66 BBuuss
EV6 Bus in the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock edge to
transfer data, similar as DDR SDRAM or ATA/66 IDE bus.
EV6 Bus Speed = CPU external bus clock x 2.
For example, 200 MHz EV6 bus is actually using 100 MHz external bus clock, but the equivalent speed is 200 MHz.
FFCCCC DDooCC ((DDeeccllaarraattiioonn ooff CCoonnffoorrmmiittyy))
The DoC is component certification standard of FCC EMI regulations. This standard allows DIY component (such as motherboard) to apply
DoC label separately without a shielding of housing.
FFCC--PPGGAA ((FFlliipp CChhiipp--PPiinn GGrriidd AArrrraayy))
FC means Flip Chip, FC-PGA is a new package of Intel for Pentium III CPU. It can plug into SKT370 socket, but require motherboard to
add some signals on socket 370. That is, the motherboard needs to be redesigned. Intel is going to ship FC-PGA 370 CPU and phase out
slot1 CPU.
FFllaasshh RROOMM
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 256KB (2M bit). AOpen AX5T is the first board to
implement 256KB (2Mbit) Flash ROM. Now flash ROM size is moving to 4M bit on AX6C (Intel 820) and MX3W (Intel 810) motherboard. ,
AOpen motherboard uses EEPROM for jumper-less and battery-less design.
