AOpen XC Cube comes with two versions of motherboard for your selection, they are separately
UX4SG-1394 (EZ65) and UK79G-1394 (EZ18). To get to know the details of them, please refer to their
respective information as below.
UX4SG-1394 Motherboard
Setting CPU Voltage and Frequency
Full-range Adjustable CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically detected and
the range is from 1.1V to 1.85V. It is not necessary to set CPU Core Voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and
no jumpers or switches are needed.

Note:
With CPU speed changing rapidly, there might be fastest CPU on
the market by the time you received this installation guide. This table is
kindly for your references only.
Note: Intel 865G chipset
don’t support Willamette
or Celeron (0.18u)
processors. Northwood
processor would detect
the clock ratio
automatically, you may
not be able to adjust the
clock ratio in BIOS
manually.
