SiS® HyperStreaming Architecture

The SiS® 655FX integrates the latest HyperStreaming Engine which greatly improves computer system performance. The HyperStreaming Engine smartly manages the data streaming to flow smoothly from the peripherals to the core logic chipsets between the North and South bridge to the Front Side Bus, memory and graphic interface.

Serial ATA solution with RAID 0, RAID 1 support

The motherboard supports two interfaces compliant to the Serial ATA (SATA) specification, an evolutionary replacement of the Parallel ATA storage interface. The Serial ATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, up to 150 MB/s data transfer rate, and software compatibility with legacy Parallel ATA. With the integrated controller in the SIS 964 chipset, the motherboard supports RAID0, RAID1 configuration using SATA drives. See pages 1-19.

CrashFree BIOS 2

This feature allows you to restore the original BIOS data from a floppy disk or support CD in case when the BIOS codes and data are corrupted. This protection eliminates the need to buy a replacement ROM chip.

AGP 8X support

AGP 8X (AGP 3.0) is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth speeds up to 2.12 GB/s. With a bus of 533Mhz, AGP 8X is twice as fast as AGP 4X.

8 USB 2.0 ports

The motherboard implements the new Universal Serial Bus (USB) 2.0 specification, extending the connection speed from 12 Mbps on USB 1.1 to a fast 480 Mbps on USB 2.0. The higher bandwidth of USB 2.0 allows connection of devices such as high resolution video conferencing cameras, next generation scanners and printers, and fast storage units. USB 2.0 is backward compatible with USB 1.1. See page 1-17.

6-channel digital audio

The ADI AD1888 SoundMAX AC ‘97 audio CODEC is onboard to provide 6- channel audio playback for 5.1 surround sound, and over 90dB dynamic range.
