VIA KT266 - The New Standard for Socket A Performance PCs

Coupling support for high-bandwidth DDR266 SDRAM with a 266MHz Front Side Bus and VIA's new high-speed V-Link Hub Architecture, the VIA Apollo KT266 provides the ultimate balanced platform for building the next generation of ultra-powerful AMD Athlon™ processor based servers, workstations, and PC systems.

The VIA Apollo KT266 provides the highest performance and most scalable chipset solution for the latest AMD Athlon™ processors with a 266MHz Front Side Bus. Through its advanced V-Link memory controller architecture, the VIA Apollo KT266 chipset supports up to 4.0GB of the latest high-speed DDR200/266 SDRAM at a peak bandwidth of 2.1GB per second. These advanced memory technologies provide the bandwidth and performance necessary for even the most demanding Internet and 3D graphics applications at a minimal cost premium over PC133 SDRAM.
