CS/ODT drive Strength Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x. CKE drive Strength Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x. Bank Interleaving Enables or disables memory bank interleaving. Enabled allows the system to simultaneously access different banks of the memory to increase memory performance and stability. (Default: Enabled) Channel interleave Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access different channels of the memory to increase memory performance and stability. (Default: Enabled) ******** System Voltage Optimized ******** System Voltage Control Determines whether to manually set the system voltages. Auto lets the BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable. (Default: Auto) CPU PLL Voltage Control Allows you to set the CPU PLL voltage. Normal Supplies the CPU PLL voltage as required. (Default) 2.220V ~ 3.100V The adjustable range is from 2.220V to 3.100V. Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU. DRAM Voltage Control Allows you to set memory voltage. Normal Supplies the memory voltage as required. (Default) 1.275V ~ 2.445V The adjustable range is from 1.275V to 2.445V. Note: Increasing memory voltage may result in damage to the memory or reduce the useful life of the memory. DDR VTT Voltage Control Allows you to set the memory VTT voltage. Normal Supplies the memory VTT voltage as required. (Default) 0.720V ~ 1.050V The adjustable range is from 0.720V to 1.050V. Note: Increasing memory voltage may result in damage to the memory or reduce the useful life of the memory. NB Voltage Control Allows you to set the North Bridge voltage. Normal Supplies the North Bridge voltage as required. (Default) 0.920V ~ 1.400V The adjustable range is from 0.920V to 1.400V. SB/HT Voltage Control Allows you to set the South Bridge/HT-Link voltage. Normal Supplies the South Bridge/HT-Link voltage as required. (Default) 0.940V ~ 1.500V The adjustable range is from 0.940V to 1.500V. BIOS Setup - 42 -
