The VIA Apollo Pro 266 is an efficient, cost-effective, flexible chipset solution for Socket 370 systems based on the Intel® Pentium® III, Intel® Celeron™ & VIA C3® Processors, across a full spectrum of applications. Through its V-Link memory controller architecture, the VIA Apollo Pro266 chipset supports up to 4.0GB of DDR200/266 SDRAM at a peak bandwidth of 2.1GB per second. These memory technologies provide the bandwidth and performance necessary for even demanding Internet and 3D graphics applications at a minimal cost premium over PC133 SDRAM. DDR266 SDRAM lowers memory power consumption as well, providing the ideal solution for small form factor desktops and notebooks. The VIA Pro266 also has a flexible 133/100/66 MHz front side bus, and its asynchronous bus design are also ideal for Pentium® III, Celeron™ & VIA C3® processors. An AGP 4X/2X controller enables connection with external graphics cards, and an ATA 100 interface delivers maximum sustained data transfer rates of 100MB/sec. A V-link chip interconnect offers 266MB/s of bandwidth between North and South Bridge.

In combination with the VIA VT8233 South Bridge Controller (see the block diagram below), the Pro266 support for six USB ports, AC-97 link for audio and modem, hardware monitoring, and ACPI/OnNow power management.
