Figure 4.2 shows the BIOS settings to achieve a processor speed of 4.72 GHz. Turbo
ratios of 45 were set for all of the processor cores. The system base clock frequency
has been increased from the default value of 100 MHz to 105 MHz. XMP profiles were
used to obtain a memory speed of 1600 MHz. These settings are shown while running
the CPU Stress Test included with the Intel Extreme Tuning Utility shown in Figure 4.3.
