The following two items appear only when you set the Ai Overclock Tuner item to [Manual]. FSB Frequency [XXX] Displays the frequency sent by the clock generator to the system bus and PCI bus. The value of this item is auto-detected by the BIOS. Input the desired CPU frequency using the numeric keypad. The values range from 200 to 800. Refer to the table below for the correct Front Side Bus and CPU External Frequency settings. FSB/CPU External Frequency Synchronization Front Side Bus FSB 1600 FSB 1333 FSB 1066 FSB 800 CPU External Frequency 400 MHz 333 MHz 266 MHz 200 MHz DRAM Frequency [Auto] Allows you to set the DDR2 operating frequency. Configuration options: [Auto] [DDR2-533 MHz] [DDR2-639 MHz] [DDR2-667 MHz] [DDR2800 MHz] The DRAM Frequency configuration options vary with the FSB Frequency item settings. Selecting a very high DRAM frequency may cause the system to become unstable! If this happens, revert to the default setting. Configure DRAM Timing by SPD [Enabled] Allows you to set the DRAM timing control. Configuration options: [Enabled] [Disabled] CPU VCORE Over-Voltage [Auto] Allows you to set the CPU VCore over-voltage. Configuration options: [Auto] [+50mv] [+100mv] [+150mv]. 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. FSB Termination Voltage [Auto] Allows you to set the front side bus termination voltage. The values range from 1.20V to 1.30V with a 0.10V interval. Press +/- to adjust the value. DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.87V to 2.26V with a 0.13V interval. Press +/- to adjust the value. Chapter 2: BIOS information 2-7
