VIA P4XB-R Mainboard

Harnessing the Power of DDR266 SDRAM for the Intel® Pentium® 4 Processor

Combining support for 3GB high bandwidth DDR266 SDRAM with a host of high end features such as an onboard Promise PDC20265R IDE RAID controller, the VIA P4XB-R mainboard provides the ultimate platform for building the highest performance 478-pin Intel® Pentium® 4 processor based systems, workstations, and servers.

Based on the highly acclaimed VIA Apollo P4X266 chipset, the VIA P4XB-R features a 400MHz Front Side Bus and supports a complete range of 478-pin Intel® Pentium® 4 processors running at speeds of up to 2GHz and above. With three 184-pin DIMM sockets onboard, the VIA P4XB-R can accommodate a maximum of 3GB DDR266 SDRAM delivering data transfers rates of up to 2.1GB per second. Overall performance is further enhanced by the VIA Apollo P4X266's high speed V-Link bus, which doubles communication bandwidth between the chipset's North and South Bridge to 266MB per second.

With one AGP4X port, five PCI slots, and a CNR slot, the VIA P4XB-R provides unsurpassed levels of scalability on an ATX form factor measuring 30.5cm x 22.5cm. In addition to onboard C-Media 6 channel audio, the board also comes with a full set of I/O ports as well as Ultra ATA-100 and Hardware Monitoring support.
