4-20 Chapter 4: BIOS setup
• Setting the CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage
and North Bridge Voltage to a high level may damage the chipset, memory
module, and CPU permanently. Proceed with caution.
• Some values of the CPU PLL Voltage, FSB Termination Voltage, DRAM
Voltage and North Bridge Voltage items are labeled in different color,
indicating the risk levels of high voltage settings. Refer to the table below
for details.
• The system may need better cooling system to work stably under high
voltage settings.
