DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.185V to 1.800V with a 0.005V interval. According to Intel CPU specifications, DIMMs with voltage requirement over 1.65V may damage the CPU permanently. We recommend that you install the DIMMs with the voltage requirement below 1.65V. PCH VLX Voltage [Auto] Allows you to set the I/O voltage on the PCH (Platform Controller Hub). You can use the or keys to adjust the value. The values range from 1.185V to 2.135V with a 0.005V interval. PCH Voltage [Auto] Allows you to set the Core voltage for the PCH (Platform Controller Hub). You can use the or keys to adjust the value. The values range from 0.735V to 1.500V with a 0.005V interval. The system may need better cooling system for a more stable performance under high voltage settings. DRAM CTRL REF Voltage [Auto] This item is the DRAM reference voltage for the control lines from the memory bus. You can use the or keys to adjust the value. The values range from 0.3950x to 0.6300x with a 0.0050x interval. DRAM DATA REF Voltage on CHA/CHB [Auto] This item is the DRAM reference voltage for the data lines on Channels A and B. You can use the or keys to adjust the value. The values range from 0.3950x to 0.6300x with a 0.0050x interval. Different ratio might enhance DRAM overclocking ability. CPU Spread Spectrum [Auto] [Auto] Automatic configuration. [Disabled] Enhances the BCLK overclocking ability. [Enabled] Sets to [Enabled] for EMI control. Chapter 3 ASUS Z87M-PLUS 3-21
