The most important settings of the SH55J2 are available under the "Advanced" tab:

We select the " CPU configuration" option where you can change the settings of your CPU. In our case, we can enable/disable the "Virtualization", "HT", "Speedstep" and "Turbomode" technologies. We can also set the maximum CPUID limit and select the number of the active cores of our CPU:

The " Onboard Device Configuration" section includes settings related to the graphics, HD audio and LAN:

The CPU/DRAM/Chipset voltages are set by selecting the predefined + offset of the standard voltages, which is not very handy for serious overclockers:
