Chapter 2: BIOS information
2.4.3
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.
2.4.4
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]
2.4.5
Intel(R) TurboMode Tech [Enabled]
This item appears only if you set the
CPU Ratio Setting item to [Auto]. Turbo mode allows
processor cores to run faster than marked frequency in specific condition.
Configuration options: [Disabled] [Enabled]
2.4.6
Xtreme Phase Full Power Mode [Auto]
[Auto]
Automatic configuration.
[Enabled]
Enables Full Power Mode to ensure the best CPU overclocking
performance.
The following two items appear only when you set the
Ai Overclock Tuner item to
[Manual], [D.O.C.P.] or [X.M.P.].
BCLK Frequency [XXX]
Allows you to adjust the Internal Base Clock (BCLK). Use the <+> and <-> keys to adjust the
value. You can also type the desired value using the numeric keypad. The values range from
80 to 500.
PCIE Frequency [XXX]
Allows you to set the PCI Express frequency. Use the <+> and <-> keys to adjust the PCIE
frequency. The values range from 100 to 200.
2.4.7
DRAM Frequency [Auto]
Allows you to set the DDR3 operating frequency.
Configuration options: [Auto] [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333]
•
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.
Selecting a very high DRAM frequency may cause the system to become unstable! If this
happens, revert to the default setting.
2.4.8
QPI Frequency [Auto]
Allows you to set the QuickPath Interconnect (QPI) frequency.
Configuration options: [Auto] [3200MHz] [3733MHz] [4800MHz] [5333MHz] [5867MHz]
