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:

Voltage Type: JP17

Voltage	1-2	3-4
Type
Single *	open	open
Dual	short	short

CPU Voltage Setting: JP30

Voltage	1-2	3-4	5-6	7-8	9-10
Value
3.52V*	open	short	short	short	short
3.3V	open	short	short	open	short
3.2V	open	short	short	open	open
3.1V	open	short	open	short	short
3.0V	open	short	open	short	open
2.9V	open	short	open	open	short
2.8V	open	short	open	open	open
2.7V	open	open	short	short	short
2.5V	open	open	short	open	short
2.2V	open	open	open	short	open
2.1V	open	open	open	open	short
