DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.185V to 2.135V 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. VCCIO Voltage [Auto] Allows you to set the VCCIO voltage. The values range from 0.735V to 1.735V with a 0.005V interval. PCH Voltage [Auto] Allows you to set the Platform Controller Hub volage. The values range from 0.735V to 1.685V with a 0.005V interval. • The values of the CPU Manual Voltage, CPU Offset Voltage, iGPU Manual Voltage, iGPU Offset Voltage, DRAM Voltage, VCCIO Voltage and PCH Voltage items are labeled in different color, indicating the risk levels of high voltage settings. • The system may need better cooling system to work stably under high voltage settings.
