4.4.9 Ai Transaction Booster [Auto] Allows you to set the system performance. Configuration options: [Auto] [Manual] The following two 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. The values range from 1 to 31. 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 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. 4.4.10 CPU Voltage [Auto] Allows you to set the CPU VCore voltage. The values range from 0.85000V to 1.60000V 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. 4.4.11 FSB Termination Voltage [Auto] Allows you to set the front side bus termination voltage. The values range from 1.20V* to 1.50V with a 0.10V interval. The minimum value of this item becomes 1.10V when a 45nm CPU is installed. 4.4.12 Memory Voltage [Auto] Allows you to set the Memory voltage. The values range from 1.80V to 3.08V with a 0.02V interval. 4.4.13 North Bridge Voltage [Auto] Allows you to set the North Bridge voltage. The values range from 1.10V to 2.06V* with a 0.02V interval. 4-20 Chapter 4: BIOS setup
