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]

• 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.
[Disabled]
You are not allowed to select the memory profile.
[High Performance] Allows your memory to work in high performance.
[High Frequency] Allows your memory to work in 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 set the ratio between the CPU Core Clock and the BCLK Frequency. Use the <+>
and <-> keys to adjust the ratio. The valid value ranges vary according to your CPU model.
3.5.3 Intel(R) SpeedStep(TM) Tech [Enabled]
[Enabled] The CPU speed is controlled by the operating system.
[Disabled] The CPU runs at its default speed.
3.5.4 Intel(R) TurboMode Tech [Enabled]
[Enabled] Allows processor cores to run faster than marked frequency in specific
condition.
[Disabled] Disables this function.
• This item appears only if you set the CPU Ratio Setting item to [Auto].
• Intel ® Turbo Mode function support depends on CPU types.
