The configuration options for the following sub-items vary depending on the CPU/DIMMs
you install on the motherboard.
OC From CPU Level Up [Auto]
This item appears only when you set the Ai Overclock Tuner item to [Manual] and allows you
to select a CPU level. The related parameters will be automatically adjusted according to the
selected CPU level.
DRAM O.C. Profile [DDR3-1800MHz]
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: [DDR3-1800MHz] [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 Ai Overclock Tuner [Auto]
Allows you to select the CPU overclocking options to achieve the desired CPU internal
frequency. Select any of these preset overclocking configuration options:
Manual Allows you to individually set overclocking parameters.
Auto Loads the optimal settings for the system.
D.O.C.P Overclocks DRAM frequency by adjusting BCLK frequency.
X.M.P.
If you install memory modules supporting the eXtreme Memory Profile
(X.M.P.) Technology, choose this item to set the profiles supported by
your memory modules for optimizing the system performance.
CPU Level Up
Allows you to select a CPU level, and the related parameters will be
adjusted automatically.
