[. . . ] Configuration options: [Auto] [Lighter] [Light] [Moderate] [Strong] [Stronger] 3-20 Chapter 3: BIOS setup 3. 4. 10 Ai Transaction Booster [Auto] Allows you to set the system performance. Configuration options: [Auto] [Manual] The following sub-items appear only when you set the Ai Transaction Booster item to [Manual]. Common Performance Level [05] Set this item to a higher level for better compatibility or a lower level for better performance. Use the <+> and <-> keys to adjust the value. Pull-In of CHA/B PH1/2/3 [Disabled] Set this item to [Enabled] to apply enhancement on DRAM Channel A and B, Phase 1 to 3. The number of phases is determined by DRAM frequency and FSB strap. Configuration options: [Disabled] [Enabled] 3. 4. 11 CPU Voltage [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_CPU jumper is enabled, otherwise the maximum voltage supported is [1. 70000V]. CPU / Northbridge overvoltage setting on page 2-21 for details. · 3. 4. 12 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. 4. 13 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. ASUS P5Q 3-21 3. 4. 14 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. 4. 15 NB Voltage [Auto] Allows you to set the North Bridge voltage. The values range from 1. 10V to 2. 20V* with a 0. 02V interval. · The value [2. 20V] of the NB Voltage item is supported only if the OV_NB jumper is enabled, otherwise the maximum voltage supported is [1. 76V]. CPU / Northbridge overvoltage setting on page 2-21 for details. 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. Some values of the 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. The system may need better cooling system to work stably under high voltage settings. Blue CPU PLL Voltage FSB Termination Voltage DRAM Voltage NB Voltage 1. 50V~1. 78V 1. 20V~1. 38V 1. 80V~1. 98V 1. 10V~1. 26V Yellow 1. 80V~2. 00V 1. 40V~1. 90V 2. 00V~2. 20V 1. 28V~1. 40V Purple 2. 02V~2. 20V N/A 2. 22V~2. 40V 1. 42V~1. 58V Red 2. 22V~2. 78V N/A 2. 42V~3. 08V 1. 60V~2. 20V · · · 3. 4. 16 SB Voltage [Auto] Allows you to set the South Bridge voltage. The values range from 1. 10V to 1. 40V with a 0. 10V interval. 3. 4. 17 PCIE SATA Voltage [Auto] Allows you to set the PCI Express SATA voltage. The values range from 1. 50V to 1. 80V with a 0. 10V interval. 3-22 Chapter 3: BIOS setup 3. 4. 18 Load-Line Calibration [Auto] Allows you to select the CPU Load-Line mode. Set to [Disabled] to follow Intel specifications, or to [Enabled] to improve CPU VDroop directly. [. . . ] Visit www. intel. com for more information on the EM64T feature.
