3.5.13 CPU Voltage [Auto] Allows you to set the CPU VCore voltage. Use the and keys or the numeric keypad to enter the desired value. The values range from 0.85000V to 2.10000V* with a 0.00625V interval. • Refer to the CPU documentation before setting the CPU Vcore voltage. Setting a high VCore voltage may damage the CPU permanently, and setting a low VCore voltage may make the system unstable. • The value [2.10000V] of the CPU Voltage item is supported only if the OV_CPU jumper is enabled, otherwise the maximum voltage supported is [1.70000V]. See 2. CPU overvoltage setting on page 2-22 for details. 3.5.14 CPU GTL Reference [Auto] Allows you to set the CPU GTL reference voltage. Different ratio might enhance CPU overclocking ability. Configuration options: [Auto] [0.65x] [0.63x] [0.61x] The following six (6) items are adjusted by typing the desired values using the numeric keypad and press the key. You can also use the and keys to adjust the value. To restore the default setting, type [auto] using the keyboard and press the key. 3.5.15 CPU PLL Voltage [Auto] Allows you to set the CPU PLL voltage. The values range from 1.50V to 2.78V with a 0.02V interval. 3.5.16 FSB Termination Voltage [Auto] Allows you to set the front side bus termination voltage. The values range from 1.20V* to 1.90V with a 0.02V interval. The minimum value of this item becomes 1.10V when a 45nm CPU is installed. 3.5.17 DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.80V to 3.08V with a 0.02V interval. 3.5.18 NB Voltage [Auto] Allows you to set the North Bridge voltage. The values range from 1.10V to 1.90V with a 0.02V interval. • Setting the CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage and NB Voltage items to a high level may damage the chipset, memory module and CPU permanently. Proceed with caution. • Some values of the CPU Voltage, CPU PLL Voltage, FSB Termination Voltage, DRAM Voltage and NB Voltage items are labeled in different color, indicating the risk levels of high voltage settings. Refer to the table on the next page for details. • The system may need better cooling system to work stably under high voltage settings. Chapter 3 3-16 Chapter 3: BIOS setup
