All Voltage Settings

► CPU Core Voltage Mode

This item is used to select the CPU Core Power Voltage setting. Options are:[Standard Mode],
[Dynamic Mode], [Fixed Mode].

► CPU Voltage Offset(1/10000 Volt)

This item is used to set the CPU voltage offset. Press "+/-" keys to change the value by 40 per
step.

► CPU VTT (Uncore) Voltage

This item is used to select the CPU VTT (Uncore) voltage. [Default] means the voltage is
according to your CPU model. It can be 1.00V or 1.05V.

► CPU PLL Voltage

This item is used to set DRAM Voltage. The default voltage is 1.8V.

►CPU VccSA Voltage

This item is used to set the CPU Vcc system agent power voltage setting. The default voltage
for SandBridge CPU is 0.925V, for other CPU is 0.850V(Ivy etc...).

►DRAM Voltage

This item is used to set the DRAM voltage. The maximum available for adjustment is 2.501V.
The default voltage is 1.521V. Adjusting the voltage beyond the memories default voltage
could result in damage to memory controller.

►DIMM1 and DIMM3 DQ Vref(Data) Volt

This item is used to set the DIMMs Channel A DQ signals reference voltage. The default
option is: [64/128 VDIMM].

►DIMM2 and DIMM4 DQ Vref(Data) Volt

This item is used to set the DIMMs Channel B DQ signals reference voltage. The default
option is: [64/128 VDIMM].

►CougarPoint PCH Core Voltage

This item is used to set the CougarPoint PCH Core Voltage. The default option is: [1.057V].
