[. . . ] [Offset Mode] Allows you to set the Offset voltage. CPU VCORE Manual Voltage [Auto] This item appears only when you set the CPU VCORE Voltage item to [Manual Mode] and allows you to set a fixed CPU VCORE voltage. The values range from 0. 800V to 1. 700V with a 0. 005V interval. ASUS P9X79 WS 3-25 Chapter 3 Offset Mode Sign [+] This item appears only when you set the CPU VCORE Voltage item to [Offset Mode]. [+] [­] To offset the voltage by a positive value. To offset the voltage by a negative value. CPU VCORE Offset Voltage [Auto] This item appears only when you set the CPU VCORE Voltage item to [Offset Mode] and allows you to set the VCORE offset voltage. The values range from 0. 005V to 0. 635V with a 0. 005V interval. CPU VCCSA Voltage [Offset Mode] This adjusts the power supply for the processor's I/O, DMI, and PCI Express Controller to help DRAM and BCLK overclocking. [Manual Mode] Allows you to set a fixed VCCSA CPU voltage. [Offset Mode] Allows you to set the VCCSA Offset voltage. CPU VCCSA Manual Voltage [Auto] This item appears only when you set the CPU VCCSA Voltage item to [Manual Mode] and allows you to set a fixed CPU VCCSA voltage. The values range from 0. 800V to 1. 700V with a 0. 005V interval. Offset Mode Sign [+] This item appears only when you set the CPU VCCSA Voltage item to [Offset Mode]. [+] [­] To offset the voltage by a positive value. To offset the voltage by a negative value. CPU VCCSA Offset Voltage [Auto] This item appears only when you set the CPU VCCSA Voltage item to [Offset Mode] and allows you to set the VCCSA offset voltage. The values range from 0. 005V to 0. 635V with a 0. 005V interval. Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage may damage the CPU permanently, and setting a low voltage may make the system unstable. Chapter 3 3-26 DRAM Voltage (CHA, CHB) [Auto] Allows you to set the DRAM voltage. The values range from 1. 20V to 1. 99V with a 0. 005V interval. DRAM Voltage (CHC, CHD) [Auto] Allows you to set the DRAM voltage. The values range from 1. 20V to 1. 99V with a 0. 005V interval. According to Intel CPU spec, DIMMs with voltage requirement over 1. 65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage requirement below 1. 65V.
