The VIA P4PB 266E mainboard is based around
the VIA Apollo P4X266E chipset, which brings sup-
port for high-performance DDR SDRAM to the Intel®
Pentium® 4 platform. VIA’s advanced 266 MB/s 8-bit
V-Link controller brings optimal system efficiency by
effectively doubling bandwidth between the chipset’s
north and south bridges. Designed for the latest 478-
pin Pentium®4 processors, these ATX sized mainboards
are the perfect choice for Pentium 4 based high- per-
formance PCs, servers and workstations.
