Chapter 3
3.5.15 CPU Differential Amplitude [Auto]
Different AMP might enhance BCLK overclocking ability.
Configuration options: [Auto] [700mV] [800mV] [900mV] [1000mV]
3.5.16 CPU Clock Skew [Auto]
Adjusting this item may help enhancing BCLK overclocking ability. You may need to adjust
the CPU Clock Skew item at the same time.
Configuration options: [Auto] [Normal] [Delay 100ps]–[Delay 1500ps]
Some of the following items are adjusted by typing the desired values using the numeric keypad
and press the <Enter> key. You can also use the <+> and <-> keys to adjust the value. To
restore the default setting, type [auto] using the keyboard and press the <Enter> key.
3.5.17 CPU Voltage Mode [Offset]
Allows you to set the CPU Voltage Mode. Different sub-items appear according to the CPU
Voltage Mode item setting. Configuration options: [Offset] [Manual]
Offset Voltage [Auto]
This item appears only when you set the CPU Voltage Mode item to [Offset] and allows you to
set the Offset voltage. The values range from 0.00625V to 0.50000V with a 0.00625V interval.
Offset Sign [-]
This item appears only when you set the Offset Voltage item to a value other than [Auto].
[+]
To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
Fixed Voltage [Auto]
This item appears only when you set the CPU Voltage Mode item to [Manual] and allows you
to set a fixed CPU voltage. The values range from 0.85V to 1.7V with a 0.00625V interval.
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.
3.5.18 IMC Voltage [Auto]
Allows you to set the CPU Integrated Memory Controller voltage. The values range from 1.1V
to 1.7V with a 0.00625V interval.
3.5.19 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V 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 2. DRAM overvoltage
setting switch on page 2-26 for details.
• 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.
