  • Page 96: Overclocking

    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 which we call them "Overclocker".

    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...

    A disc bundled with AOpen motherboard product; there are motherboard drivers, Acrobat Reader for online manual and other useful utilities. Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power management. ATA is the specification of diskette interface. In 80’s , many software and hardware manufacturers instituted the ATA specification together.

  • Page 100: Ata/100

    ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle ime 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.

  • Page 101: Bus Master Ide (Dma Mode)

    The traditiona l 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.

  • Page 102: Dimm (Dual In Line Memory Module)

    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, which operate at 3.3V. Note that some old DIMMs are made by FPM/EDO and only operate at 5V.

  • Page 103: Eeprom (Electronic Erasable Programmable Rom)

    Also known as E PROM. 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. 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.

  • Page 104: 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 e 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.

    IEEE 1394 is a lo w-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.

  • Page 106: Dimm

    SDRAM DIMM that supports 100MHz CPU bus clock. SDRAM DIMM that supports 133MHz CPU bus clock. Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333 MHz three types of working frequency. Because of DDR DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, and 266x64/8=2100MB/s, and 333x64/8=2700MB/s.

  • Page 107: Pnp (Plug And Play)

    he PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95). These registers are used b y BIOS and operating system to configure system resource and prevent any conflicts. PnP BIOS or operating system will automatically allocate the IRQ/DMA/Memory.

    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 BIOS to decide best timing for this DIMM or RIMM. Ultra DMA (or, more accur ately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer’s dat path (or...

    NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves t he memory system’s ability o service multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set o f fast static registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency a nd reduced power consumption.
