The configuration options for the following sub-item vary depending on the

DIMMs you install on the motherboard.

DRAM O.C. Profile [DDR3-1339MHz]

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: [DDR3-1339MHz] [DDR3-1603MHz]

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.

3.4.2CPU Ratio Setting [Auto]

Allows you to adjust the ratio between CPU Core Clock and BCLK Frequency. Use the <+> and <-> keys to adjust the value.

Configuration options: [Auto] [12.0] [13.0] [14.0] [15.0] [16.0] [17.0] [18.0] [19.0] [20.0]
