The configuration options for the following sub-item vary depending on the DIMMs you
install on the motherboard.
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]

• When using DIMMs with a frequncy higher than the Intel ® CPU spec, use this ASUS
exclusive DRAM O.C. Profile function to overclock the DRAM.
• Adjust BCLK frequency to obtain a better performance after applying the D.O.C.P
function.
eXtreme Memory Profile [High Performance]
This item appears only when you set the Ai Overclock Tuner item to [X.M.P.] and
allows you to select the X.M.P. mode supported by your memory module.
Configuration options: [High Performance] [High Frequency]
To obtain the best performance of the X.M.P. DIMM or 1600MHz DIMM, install only one
DIMM on each memory channel.
3.5.2 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.
3.5.3 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]
3.5.4 Intel(R) TurboMode Tech [Enabled]
This item appears only if you set the CPU Ratio Setting item to [Auto]. Turbo mode allows
processor cores to run faster than marked frequency in specific condition.
Configuration options: [Disabled] [Enabled]
