PCIe Frequency can be set up to 148MHz. This is usually FIXED at 100MHz to prevent accelerating the PCIe devices

For ES CPU, you will be able to change the multiplier of the CPU from 6 ~ 11.

CPU Voltage can still be adjusted upwards with this option. A maximum of +350mV can be added to the base voltage.

VRAM (VDIMM) voltage can be adjusted. The default is 1.91v which you can set it up to 2.38v if you intend to use aggressive settings like high frequency.
