Soyo SY-K7VTA Pro VIA KT133A socket A
Wednesday, April 11, 2001
Introduction
Riding the wave of new Socket A boards based on the VIA KT133A chipset, the Soyo K7VTA Pro recently made its way to our doorstep. Ever-faithfull to the path set by its predecessors, the Soyo SY-K7VTA Pro includes such well-known features as the Soyo Combo Features menu - a BIOS menu system similar to Abit's Soft Menu - to allow easy-access to common system settings.
Let's take a closer look at our newest contender.

Configuration
Configuration of the CPU can be accomplished through the combined use of jumper & Dip-switch settings, and BIOS functions.
Jumpers FJ1 and FJ2, for their part, can be used to force the FSB to operate at either 100MHz or 133MHz. Whatever setting is chosen, it will however affect the FSB options provided by the BIOS. Selecting a jumper setting of 100MHz, for instance, will result in the BIOS providing frequency-options ranging from 100MHz to 120MHz. Selecting 133MHz provides frequencies from 133MHz to 165MHz.
The Dip switch array labeled RF1, on the other hand, can be used to set the CPU's clock multiplier setting.
Setting of the Vcore voltage, and fine-tuning of the FSB can be accomplished from within the Soyo Combo Features menu.
The "Advanced Chipset Features" menu can be used to set the operating frequency of the memory bus to either 100MHz or 133MHz.
Unfortunately, no BIOS options are provided that would allow users to adjust either the VIO voltage, or clock multiplier setting.
