CPU VDDA Voltage [Auto] Allows you to select the CPU VDDA voltage. Configuration options: [Auto] [2.50V] [2.6V] [2.7V] [2.8V] CPU-NB HT Link Speed [Auto] Allows you to set the CPU-Northbridge HyperTransport link speed. Configuration options: [Auto] [200 MHz] [400 MHz] [600 MHz] [800 MHz] [1 GHz] [1.2 GHz] [1.4 GHz] [1.6 GHz] [1.8 GHz] The following four items appear only when you set the Ai Overclocking item to [Manual], [Standard], or [Overclock Profile] and 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. DDR Voltage [Auto] Allows selection of the DDR2 reference voltage. The values range from 1.80V to 2.50V with a 0.02V interval. Northbridge Voltage [Auto] Allows you to set the Northbridge voltage. The following three items appear when you set Northbridge Voltage to [Manual]. Configuration options: [Auto] [Manual] HyperTransport Voltage [Auto] You can enter the desired HyperTransport voltage using the numeric keypad. The values range from 1.20V to 1.50V with a 0.02V interval. Core/PCIe Voltage [Auto] You can enter the desired Core/PCIe voltage using the numeric keypad. The values range from 1.10V to 1.40V with a 0.02V interval. Southbridge Voltage [Auto] You can enter the desired Southbridge voltage using the numeric keypad. The values range from 1.20V to 1.40V with a 0.02V interval. • Setting Processor Voltage, DDR Voltage, Core/PCIe Voltage and Southbridge Voltage to a high level may damage the CPU, memory module, and chipset permanently. Proceed with caution. • Some values of the items mentioned above are labeled in different color, indicating the risk levels of high voltage settings. Refer to the table below for details. • The system may require better cooling system to work stably under high voltage settings. 3-18 Chapter 3: BIOS setup
