Setting this item to [Disabled] may help enhance DRAM overclocking ability. Configuration options: [Auto] [Disabled] [Enabled] 3. 4. 9 MEM. OC Charger Allows you to enable or disable the memory overclocking charger feature. Setting this item to [Enabled] may help enhance DRAM overclock ability. Configuration options: [Auto] [Disabled] [Enabled] 3. 4. 10 Ai Clock Twister [Auto] Allows you to set the DRAM performance. Set this item to [Light] or [Lighter] to enhance DRAM compatibility, or [Strong] or [Stronger] to accelerate DRAM performance. Configuration options: [Auto] [Lighter] [Light] [Moderate] [Strong] [Stronger] 3. 4. 11 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. 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. 3-20 Chapter 3: BIOS setup 3. 4. 12 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]. [. . . ] Press <Enter> when the Create Volume item is highlighted. The following warning message appears. WARNING: ALL DATA ON SELECTED DISKS WILL BE LOST. Are you sure you want to create this volume?(Y/N): 9. Press <Y> to create the RAID volume and return to the main menu or <N> to go back to the Create Volume menu.
