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. Prole [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. prole, which applies different settings to DRAM frequency,
DRAM timing and DRAM voltage. Conguration options: [DDR3-1800MHz] [DDR3-1866MHz]
[DDR3-2000MHz] [DDR3-2133MHz] [DDR3-2200MHz]

to select the X.M.P. mode supported by your memory module.
[Disabled] You are not allowed to select the memory prole.
[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 conguration 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 Prole
(X.M.P.) Technology, choose this item to set the proles supported by
your memory modules for optimizing the system performance.
CPU Level Up
