[+] 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. 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.
