Some of the following 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. CPU Manual Voltage [Auto] This item appears only when you set the CPU Voltage item to [Manual Mode] and allows you to set a fixed CPU voltage. The values range from 0.800V to 2.155V with a 0.005V interval. The 2.155V voltage is available only when the Extreme OV item is set to [Enabled]. Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage may damage the CPU permanently, and setting a low voltage may make the system unstable. iGPU Offset Mode Sign [+] This item allows you to set iGPU offset settings. [+] To offset the voltage by a positive value. [-] To offset the voltage by a negative value. iGPU Offset Voltage [Auto] This item allows you to set the iGPU Offset voltage. The values range from 0.005V to 0.635V with a 0.005V interval. DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.20V to 2.20V with a 0.00625V interval. The 2.20V voltage is available only when the Extreme OV item is set to [Enabled]. According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage requirement below 1.65V. DRAM DATA REF Voltage on CHA/B [Auto] Allows you to set the DRAM DATA Reference Voltage on Channel A/B. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. DRAM CTRL REF Voltage on CHA/B [Auto] Allows you to set the DRAM Control Reference Voltage on Channel A/B. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability. 3-12 Chapter 3: BIOS setup
