iGPU Manual Voltage [Auto] This item appears only when you set the iGPU Voltage item to [Manual Mode] and allows you to set a fixed iGPU voltage. The values range from 0.800V to 1.990V with a 0.005V interval. DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.20V 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. VCCSA Voltage [Auto] Allows you to set the VCCSA voltage. The values range from 0.610V to 1.560V with a 0.005V interval. PCH Voltage [Auto] Allows you to set the Platform Controller Hub voltage. 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, VCCSA 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.
