CPU VCCSA Voltage [Manual Mode] •[Manual Mode] Allows you to set a fixed CPU voltage. •[Offset Mode] Allows you to set the Offset voltage. This item appears only when you set the CPU VCCSA Voltage item to [Manual Mode] CPU VCCSA Manual Voltage [Auto] This item allows you to set a fixed CPU voltage. The values range from 0.800V to 1.700V with a 0.005V interval. This item appears only when you set the CPU VCCSA Voltage item to [Offset Mode]. Offset Mode Sign [+] [+] To offset the voltage by a positive value. [-] To offset the voltage by a negative value. CPU VCCSA Offset Voltage [Auto] This item allows you to set the Offset voltage. The values range from 0.005V to 0.635V with a 0.005V interval. DRAM Voltage (CHA, CHB) [Auto] Allows you to set the DRAM voltage for DRAM channel A and B. The values range from 1.20V to 2.30V with a 0.005V interval. DRAM Voltage (CHC, CHD) [Auto] Allows you to set the DRAM voltage for DRAM channel C and D. The values range from 1.20V to 2.30V with a 0.005V interval. According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage the CPU permanently. We recommend that you install the DIMMs with the voltage requirement below 1.65V. CPU PLL Voltage [Auto] Allows you to set the CPU PLL voltage. The values range from 1.2500V to 2.5000V with a 0.00625V interval. PCH 1.1v Voltage [Auto] Allows you to set the 1.1v Platform Controller Hub voltage. The values range from 0.8000V to 1.6000V with a 0.00625V interval. Initial PLL Termination Voltage [Auto] PLL Termination Voltage set before Memory Sizing. Eventual PLL Termination Voltage [Auto] PLL Termination Voltage set before entering OS. Chapter 3 3-18 Chapter 3: BIOS setup
