ASUS P7P55-M 2-11
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-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]
eXtreme Memory Profile [Disabled]
This item appears only when you set the Ai Overclock Tuner item to [X.M.P.]
To obtain the best performance of the X.M.P. DIMM or 1600MHz DIMM, install only one
DIMM on each memory channel.
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.
Intel(R) SpeedStep(TM) Tech [Enabled]
When set to [Disabled], the CPU runs at its default speed. When set to [Enabled], the CPU
speed is controlled by the operating system. Configuration options: [Disabled] [Enabled]
BCLK Frequency [XXX]
Allows you to adjust the CPU operating frequency to enhance the system performance.
Use the <+> and <-> keys to adjust the value. You can also key in the desired value
using the numeric keypad. The values range from 133 to 500. This item appears only
when you set the Ai Overclock Tuner item to [Manual] or [D.O.C.P.]
PCIE Frequency [XXX]
Allows you to set the PCI Express frequency. Use the <+> and <-> keys to adjust the
PCIE frequency. You can also key in the desired value using the numeric keypad. The
values range from 100 to 160. This item appears only when you set the Ai Overclock
Tuner item to [Manual] or [D.O.C.P.]
