DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.20V to 2.20V with a 0.00625V 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 0.80V to 1.70V with a 0.00625V interval. VCCIO Voltage [Auto] Allows you to set the VCCIO voltage. The values range from 0.80V to 1.70V with a 0.00625V interval. CPU PLL Voltage [Auto] Allows you to set the CPU and PCH PLL voltage. The values range from 1.20V to 2.20V with a 0.00625V interval. PCH Voltage [Auto] Allows you to set the Platform Controller Hub voltage. The values range from 0.80V to 1.70V with a 0.01V interval. • The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA Voltage, VCCIO Voltage, CPU PLL Voltage, and PCH Voltage items are labeled in different color, indicating the risk levels of high voltage settings. Refer to the table below for details. • The system may need better cooling system to work stably under high voltage settings.
