2-14 ASUS P8Q77-M
CPU Offset Voltage [Auto]
Allows you to set the CPU Offset voltage. The values range from 0.005V to 0.635V with a 0.005V
interval.
Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage
may damage the CPU permanently, and setting a low voltage may make the system
unstable.
2.4.8 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 specification, 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.
2.4.9 VCCIO Voltage [Auto]
Allows you to set the VCCIO voltage. Configuration options: [Auto] [+0.10V]
2.4.10 VCCSA Voltage [Auto]
Allows you to set the VCCSA voltage. Configuration options: [Auto] [+0.05V]
2.4.11 CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. Configuration options: [Auto] [+0.10V]
2.4.12 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.7350V to
1.6850V with a 0.0050V interval.
• The values of the CPU Offset Voltage, DRAM 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.
2.4.13 Load-Line Calibration [Auto]
Load-line is defined by Intel VRM specification and affects CPU voltage. The CPU working
voltage will decrease proportionally to CPU loading. Higher load-line calibration would get
higher voltage and better overclocking performance, but increase the CPU and VRM thermal.
This item allows you to set this function for better system performance. Configuration options:
[Auto] [Enabled] [Disabled]
The actual performance boost may vary depending on your CPU specification.
