The VIA P4PA mainboard is based around the
VIA Apollo P4X266A chipset, which brings support
for high-performance DDR266 SDRAM to the Intel®
Pentium® 4 platform. VIA’s advanced V-Link controller
brings optimal system efficiency by effectively dou-
bling bandwidth between the chipset’s north and south
bridges. Designed for the latest 478-pin Pentium®4
processors, these ATX sized mainboards are the per-
fect choice for Pentium 4 based high- performance PCs,
servers and workstations.
