DRAM O.C. Profile [DDR3-1600MHz]
This item appears only when you set the Ai Overclock Tuner item to [D.O.C.P.] and
allows you to select a DRAM O.C. profile, which applies different settings to DRAM
frequency, DRAM timing and DRAM voltage.
Configuration options: [DDR3-1600MHz] [DDR3-1800MHz] [DDR3-1866MHz] [DDR3-
2000MHz] [DDR3-2133MHz] [DDR3-2200MHz]
The configuration options for the following sub-item vary depending on the DIMMs you
install on the motherboard.
To obtain the best performance of the X.M.P. DIMM or 1600MHz DIMM, install only one
DIMM on each memory channel.
2.4.2 CPU Ratio Setting [Auto]
Allows you to adjust the ratio between CPU Core Clock and BCLK Frequency. Use the <+>
and <-> keys to adjust the value. The valid value ranges differently according to your CPU
model.
2.4.3 Intel(R) SpeedStep(TM) Tech [Enabled]
When set to [Disabled], the CPU runs at its default speed. When set to [Enabled], the CPU
speed is controlled by the operating system. Configuration options: [Disabled] [Enabled]
2.4.4 Intel(R) TurboMode Tech [Enabled]
This item appears only if you set the Ratio CMOS Setting item to [Auto]. Turbo mode allows
processor cores to run faster than marked frequency in specific condition. Configuration
options: [Disabled] [Enabled]
2.4.5 Xtreme Phase Full Power Mode [Auto]
[Auto] Automatic configuration.
[Enabled] Enables Full Power Mode to ensure the best CPU overclocking
performance.
eXtreme Memory Profile [Disabled]
This item appears only when you set the Ai Overclock Tuner item to [X.M.P.]
