Voltage Adjustment for Matsonic VIA APollo pro 133a motherboard?

[Strae]

Hi I just bought a Matsonic MS7177C mainboard. Manual and website claim that I can adjust voltage and clock speeds. clock speed is there, but no voltage setting and the chip is unstable at normal voltage.

This board uses the VIA VT82C686B chipset.

Anyone know of a way for me to adjust the voltages or to get the option in BIOS?
TIA,

Hi! I have the same mob with a celron fcpga 600 the board auto detects the voltage fine. 1.75v for mine . Maybe try the bios flash at matsonic include the hardware monitor too. Before that clear cmos with jp1 and reboot it may detect it better next time.
