This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if you are not overclockers, we

recommend you to set it to the default setting. Additionally, this motherboard also provides “1MHz Stepping Adjustment”

feature for overclockers to adjust CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment range

has two levels: 100~132 (FSB=100, such as Athlon 800), 133~166 (FSB=133, such as Athlon 1000) MHz for your choosing. You

may also choose a specific FSB frequency ranging from 100~117 (say, 105, 110, 115 for example) and 120~156 with reference

to a frequency table in BIOS setup program. If you fix the CPU FSB frequency by JP21, the “1MHz Stepping Adjustment” range

will be changed and following your JP21 setting.

As a leading manufacturer in motherboard industry, AOpen always listens to what customers want and develop products to fit

different user's requirements. Reliability, compatibility, leading technology and friendly features are our basic goals when

designing motherboards. Other than above mentioned design criteria, there are power users who are always seeking to push

the limitation of the system performance by overclocking who we call them "Overclocker".

This section is dedicated to overclockers.

This high performance motherboard is designed for maximum 133MHz CPU bus clock. But it comes with clock generator of

166MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 150MHz is achievable when

proper setting and qualified components were presented, but not guarantee that it would work properly on your side. The CPU

clock ratio can be up to 12.5x that supports almost all of Athlon / Duron CPUs in the future and provides flexibility for

overclockers..

But not guaranty. ☺

Tip: Note that overclocking may also

cause thermal problem. Please make

sure that the cooling fan and the

heatsink were adequate to dissipate

excessive heat that's generated by

overclocking the CPU.

Warning: 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, SDRAM, hard disks, and AGP VGA cards.

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

to operating system (such as Windows 98). This is a bit similar as the

power switch to control the power state transition.

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

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.

MMKK7777--333333 OOnnlliinnee MMaannuuaall

AATTAA//110000

ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/6 6 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.

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.

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

IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394

working group. The IEEE 1394 can transport data at 100, 200 or 400 Mbps. One of the solutions to connect digital television

devices together at 200 Mbps. Serial Bus Management provides overall configuration control of the serial bus in the form of

optimizing arbitration timing, guarantee of adequate electrical power for all devices on the bus, assignment of isochronous

channel ID, and notification of errors. There are two type of IEEE 1394 data transfer: asynchronous and isochronous.

Asynchronous transport is the traditional computer memory-mapped, load and store interface. Data requests are sent to a

specific address and an acknowledgment is returned. In addition to an architecture that scales with silicon technology, IEEE

1394 features a unique isochronous data channel interface. Isochronous data channels provide guaranteed data transport at a

pre-determined rate. This is especially important for time-critical multimedia data where just-in-time delivery eliminates the need

for costly buffering.

PPaarriittyy BBiitt

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.

PPBBSSRRAAMM ((PPiippeelliinneedd BBuurrsstt SSRRAAMM))

For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits). PBSRAM only needs one address

decoding time and automatically sends the remaining QWords to CPU according to a predefined sequence. Normally, it is

3-1-1-1, total 6 clocks, which is faster than asynchronous SRAM. PBSRAM is often used on L2 (level 2) cache of Socket 7 CPU.

RRDDRRAAMM ((RRaammbbuuss DDRRAAMM))

Rambus is a memory technology that uses large burst mode data transfer. Theoretically, the data transfer should be high than

. RDRAM is cascaded in channel operation. For Intel 820, only one RDRAM channel is supported, 16-bit data per

RDRAM devices.

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

SSIIMMMM ((SSiinnggllee IInn LLiinnee MMeemmoorryy MMoodduullee))

SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it

was called Single In Line. SIMM is made by FPM or

current motherboard design.

SSMMBBuuss ((SSyysstteemm MMaannaaggeemmeenntt BBuuss))

SMBus is also called I2C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC).

For example, 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.

SSPPDD ((SSeerriiaall PPrreesseennccee DDeetteecctt))

SPD is a small ROM or EEPROM device resided on the DIMM or RIMM. SPD stores memory module information such as DRAM

timing and chip parameters. SPD can be used by

DRAM and supports 32-bit data. SIMM had been phased out on

EDO

to decide best timing for this DIMM or RIMM.

UUllttrraa DDMMAA

Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the

computer’s data path (or bus) to the computer’s random access memory (RAM). The Ultra DMA/33 protocol transfers data in

burst mode at a rate of 33.3MB/s, twice as fast as the previous Direct Access Memory (DMA)

developed as a proposed industry standard by the Quantum corporation, makes of hard disk drives, and Intel, makes of chipset

that support computer bus technology. Ultra DMA support in your computer means that it will boot (start) and open new

applications more quickly. It will help users of graphic-intensive and applications that require large amounts of access to data on

the hard disk drive. Ultra DMA uses Cyclical Redundancy Checking (CRC), offering a new level of data protection. Ultra DMA

uses the same 40-pin IDE interface cable as PIO and DMA.

16.6MB/s x6 = 100MB/s

VVCCMM ((VViirrttuuaall CChhaannnneell MMeemmoorryy))

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.
