Tsunami ATX (S1846) 

  Benefits and Applications

 Tyan Tsunami ATX is a quality, high performance single processor system platform that supports the powerful Intel Pentium II / III  microprocessors. This mainboard is designed around the Intel 440BX AGPset.  Please refer to the Motherboard CPU Compatibility Chart for more specs.

The Tsunami ATX supports SPD SDRAM  memory and  ECC SDRAM.  The board's PCI Local Bus and new 32-bit AGP bus provides high performance capabilities that are ideal for a wide range of applications for general business users.

This integrated system board achieves the highest reliability and is based on an ATX form factor. Some of the features included are: on-board dual channel PCI IDE,  on-board floppy controller, on-board high speed I/O, Universal Serial Bus, on-board PS/2 mouse connector, and optional on-board wavetable sound and System Mangement.

Flexibility and expandibility are designed in theTsunami ATX. With I/O and drive controller support built on-board, the Tsunami ATX allows many upgrade paths not found on other boards. With three 168-pin DIMM sockets,  the Tsuanmi ATX can provide a very flexible memory configuration of up to 768 MB  SPD SDRAM or SDRAM+ECC in addition to the 100 MHz SDRAMs.
