• Refer to the CPU documentation before setting the CPU Vcore voltage. Setting a high VCore voltage may damage the CPU permanently, and setting a low VCore voltage may make the system unstable. • If the OV_CPU switch is enabled, the adjustable voltage range from [1.25V] to [2.1V]. If the OV_CPU switch is disabled, the adjustable voltage range from [0.85V] to [1.7V]. Refer to 4. CPU / IMC / DRAM overvoltage setting on page 2-27 for details. 3.5.16 IMC Voltage [Auto] Allows you to set the CPU Integrated Memory Controller voltage. The values range from 1.1V to 1.9V* with a 0.00625V interval. The value [1.9V] of the IMC Voltage item is supported only if the OV_IMC switch is enabled. Otherwise the maximum voltage supported is [1.7V]. Refer to 4. CPU / IMC / DRAM overvoltage setting on page 2-27 for details. 3.5.17 DRAM Voltage [Auto] Allows you to set the DRAM voltage. The values range from 1.2V to 2.5V* with a 0.0125V interval. • The value [2.5V] of the DRAM Voltage item is supported only if the OV_DRAM switch is enabled. Otherwise the maximum voltage supported is [2.0V]. This item can be automatically optimized if you install a XMP DIMM. Refer to 4. CPU / IMC / DRAM overvoltage setting on page 2-27 for details. • According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect the CPU. 3.5.18 CPU PLL Voltage [Auto] Allows you to set the CPU PLL voltage. The values range from 1.8V to 2.0V with a 0.0125V interval. 3.5.19 PCH Voltage [Auto] Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 2.00V with a 0.0125V interval. • The values of the IMC Voltage, DRAM 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 on the next page for details. • The system may need better cooling system to work stably under high voltage settings. Chapter 3 ASUS P7P55D-E Deluxe 3-21
