2-1 CPU VOLTAGE SETTING (JP17, JP30)
JP17 and JP30 are the only jumpers that you need to set for your
CPU voltage on this mainboard.
There are two kinds of CPU voltages currently on the market
depending on the CPU manufacturer:
Ø Single Voltage (CPU: P54C, AMD-K5, Cyrix 6x86, IDT
WinChip C6)
Ø Dual Voltage (CPU: P55C, AMD-K6, AMD-K6-2 Cyrix
6x86L,Cyrix 6x86MX, Cyrix M II)
Those processors may come in various voltages on different
markets. Therefore, always make sure you know the type of the
CPU you are installing and adjust the settings on JP17 and JP30
accordingly.
This motherboard supports CPU voltages from 2.0 to 3.52V in 0.1V
increments. Use the following tables to set the CPU voltage jumpers
JP17 and JP30 to match the voltage value of your CPU:
