two single-sided DIMMs when the DDR DRAM interface
is operating at 133 MHz. Installing DDR DIMM modules
that exceed these specifications requires that the BIOS
down-shifts the DRAM clocks to 100 MHz through a
two-wire interface of the system clock generator.

3.2 Installation
The LV-666 is designed to fit into a standard Mini-ITX ATX form factor chassis.
The pattern of the mounting holes and the position of the back panel connectors
meet the Mini-ITX ATX system board specification. The chassis comes with
various mounting fasteners, which are made of metal or plastic. It is highly
recommended to use as many metal fasteners as possible to mount the
motherboard in the chassis for better grounding.
To install the motherboard you need to install the DDR memory modules, attach
the connectors, and set the correct CPU speed in the CMOS setup.
3.3 Safety Measures
Computer components and electronic circuit boards can be damaged by
discharges of static electricity. Working on computers that are still connected to a
power supply can be extremely dangerous. Follow the simple guidelines below
to avoid damaging you computer:
1. Always disconnect the motherboard from the ATX power supply, and
disconnect the computer from the power outlet whenever you are working
inside the computer case.
2. If possible, wear a grounded wrist strap when you are installing the
motherboard or working inside the computer case. Alternatively, discharge any
static electricity by touching the bare metal chassis of the computer case, or
the bare metal body of ay other grounded appliance.
3. Hold electronic circuit boards by the edges only. Do not touch the components
on the board unless it is necessary to do so. Do not flex or stress the circuit
board.
Leave each component inside the static-proof packaging that it ships with until you
are ready to use the component for the installation.
