3.5.2 CPU Ratio Setting [Auto]
Allows you to set the ratio between the CPU Core Clock and the BCLK Frequency. Use <+>
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.
The configuration options for the following sub-items 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.
[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.
