Online Manual AX4T II L o w E S R C a p a c i t or A group of large capacitors that meet the requirements of today’s high performance motherboard design. The theory behind this is long transmission lines have considerable inductance and capacitance as well as resistance. When a current flows through the line, inductance and capacitance have the effect of varying the voltage on the line as the current varies. Thus the supply voltage varies with the load.
Online Manual AX4T II 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 18A current is applied.

D D R ( D o u b l e Da t a R a te d ) S D R A M 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.
Online Manual AX4T II E C C ( E r r or C he c k i n g a n d C or r e c t i o n ) 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. E DO ( E x t e n de d Da t a O u t p u t ) M e m or y The EDO DRAM technology is actually very similar to FPM (Fast Page Mode).
Online Manual AX4T II EV 6 B u s 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. F C C D o C ( De c l a r a t i o n o f C o n f o r m i ty ) The DoC is component certification standard of FCC EMI regulations.
Online Manual AX4T II F S B ( F r o n t S i d e B u s ) C l oc k FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio I2C Bus See SMBus. IE EE 1 39 4 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.
Online Manual AX4T II P a r i t y Bi t 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. P BS R A M ( P i p e l i n e d B u r s t S R A M ) For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits).
Online Manual AX4T II P CI ( P e r i ph e r a l C o m p o ne n t I n te r f a c e ) B u s Bus for the internal connection of peripheral devices, high-speed data channel between the computer and expansion card. P D F F o r ma t A file format for electronic document, PDF format is independent from platform, you can read PDF file under Windows, Unix, Linux, Mac … with different PDF reader.
Online Manual AX4T II R D R A M ( R a mb u s D R A M ) Rambus is a memory technology that uses large burst mode data transfer. Theoretically, the data transfer should be high than SDRAM. RDRAM is cascaded in channel operation. For Intel 820, only one RDRAM channel is supported, 16-bit data per channel, and this channel may have maximum 32 RDRAM devices, no matter how many RIMM sockets. R I M M ( Ra m b u s I n l i n e M e m o r y M o d u l e ) 184-pin memory module that supports RDRAM memory technology.
Online Manual AX4T II S I M M ( S i n gl e I n Li n e Me m o r y M o d u l e ) 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 EDO DRAM and supports 32-bit data. SIMM had been phased out on current motherboard design. S M B us ( S y s te m Ma n a g e m e n t B us ) SMBus is also called I2C bus.
Online Manual AX4T II U l t ra D M A 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) interface.
Online Manual AX4T II 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.
Online Manual AX4T II T r ou b l e s h o o t i n g If you encounter any trouble to boot you system, follow the procedures accordingly to resolve the problem. Start Turn off the power and unplug the AC power cable, then remove all of the add-on cards and cables, including VGA, IDE, FDD, COM1, COM2 and i t Make sure if all jumper settings are correct.
Online Manual AX4T II Continue Install the VGA card. Then connect your monitor and keyboard. Turn on the power Yes and check if the power supply and CPU fan work properly. No The problem is probably caused by power supply or motherboard failure. Please contact your reseller or local distributor for repairing.
Online Manual AX4T II Continue No Check if there is display? Perhaps your VGA card or monitor is defective. Yes Press and key at the same time, hold them and then press to reboot the system. No Check if the system reboots? Yes Next 92 It is very possible that your keyboard is defective.
Online Manual AX4T II Continue During system rebooting, press to enter BIOS setup. Choose “Load Setup Default”. Turn off the system and re-connect IDE cable. Check if the system can No reboot successfully? Yes Re-install the operating system such as Windows 98. End 93 The problem should be caused by the IDE cable or HDD itself.
