Automatic configuration.
Enables Full Power Mode to ensure the best CPU overclocking
performance.
The DRAM Frequency configuration options vary with the BCLK Frequency item
settings.
According to Intel CPU spec, CPUs with a core frequency of 2.66G support the
maximum DIMM frequency of up to DDR3 1333. To use DIMMs of a higher frequency
with a 2.66G CPU, enable the DRAM O.C. Profile feature in BIOS. Refer to section
2.4.2 Ai Overclock Tuner for details.
