Processor The mainboard supports the Socket 370 which has the follow-
ing features:
•Accomodates Intel Pentium !!! processor, Tualatin proc-
essor and VIA C3 processor
•Supports 66/100/133 MHz CPU front-side bus (FSB)
Chipset The VT8601T Northbridge and VT82C686B Southbridge chip-
sets are based on a high compatibility and power efficient with
proven reliability and performance.
•Built-in PLL (Phase Lock Loop) circuitry for optimal skew
control within and between clocking regions
•Supports full AGP v1.0 capability with the internal 2D/3D
Graphics Engine for maximum software compatibility
•PCI bus is synchronous / pseudo-synchronous to host
CPU bus
•DRAM interface synchronous or pseudosynchronous with
CPU FSB speed of 133 / 100 / 66 MHz
•Support high performance rCADE3DTM accelerator
