Ai Overclock Tuner [Auto]
Allows selection of CPU overclocking options to achieve desired CPU internal frequency.
Select either one of the 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 module(s) supporting the eXtreme
Memory Profile (X.M.P.) Technology, choose this item to set the
profile(s) supported by your memory module(s) for optimizing
the system performance.
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-

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.
3.5.4
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.
