[. . . ] Pull-In of CHA/B PH1/2/3/4 [Disabled] Set this item to [Enabled] to apply enhancement on DRAM Channel A and B, Phase 1 to 4. The number of phases is determined by DRAM frequency and FSB strap. Configuration options: [Disabled] [Enabled] The following ten (10) items on the next page are adjusted by typing the desired values using the numeric keypad and press the <Enter> 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 <Enter> key. ASUS P5Q Deluxe 3-19 3. 4. 12 CPUVoltage[Auto] Allows you to set the CPU VCore voltage. 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_CPUjumper is enabled, otherwise the maximum voltage supported is [1. 70000V]. See 2. CPU/Northbridgeovervoltagesetting on page 2-19 for details. · 3. 4. 13 CPUGTLVoltageReference(0/2)[Auto] Allows you to set the CPU GTL voltage reference. The values range from 0. 370x to 0. 760x with a 0. 005x interval. Different ratio might enhance CPU overclocking ability. 3. 4. 14 CPUGTLVoltageReference(1/3)[Auto] Allows you to set the CPU GTL voltage reference. The values range from 0. 410x to 0. 800x with a 0. 005x interval. Different ratio might enhance CPU overclocking ability. 3. 4. 15 CPUPLLVoltage[Auto] Allows you to set the CPU PLL voltage. The values range from 1. 50V to 2. 78V with a 0. 02V interval. 3. 4. 16 FSBTerminationVoltage[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. 4. 17 DRAMVoltage[Auto] Allows you to set the DRAM voltage. The values range from 1. 80V to 3. 08V with a 0. 02V interval. 3. 4. 18 NBVoltage[Auto] Allows you to set the North Bridge voltage. The values range from 1. 10V to 2. 2V* with a 0. 02V interval. 3-20 Chapter 3: BIOS setup · The value [2. 2V] of the NBVoltage item is supported only if the OV_NB jumper is enabled, otherwise the maximum voltage supported is [1. 9V]. See 2. CPU/Northbridgeovervoltagesetting on page 2-19 for details. Setting the CPUPLLVoltage, FSBTerminationVoltage, DRAMVoltage and NBVoltage items to a high level may damage the chipset, memory module and CPU permanently. Some values of the CPUPLLVoltage, FSBTerminationVoltage, DRAM Voltage and NBVoltage items are labeled in different color, indicating the risk levels of high voltage settings. The system may need better cooling system to work stably under high voltage settings.
