CPU Turbo Mode
The Intel i7 processors have a Turbo Mode feature that is essentially an ‘on-demand’ overclocking mechanism that
can run the CPU temporarily faster than the maximum rated CPU frequency when both cores of the CPU are not
100% utilized. This mode of operation results in large instantaneous dynamic swings in power supply current. As a
result, spurious resets of the board may be experienced with Turbo Mode enabled if the power supply and/or
backplane combination are insufficient.
Turbo Mode can be enabled/disabled in the BIOS setup. It can be found in the Advanced > Thermal Configuration
screen.
