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
3.5.2 Ai Overclock Tuner for details.
Selecting a very high DRAM frequency may cause the system to become unstable! If this
happens, revert to the default setting.
