Failure to do so may cause physical injuries to you and damages to motherboard
components.
In order to avoid damage from static electricity to the motherboard’s components,
•
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
•
in the bag that comes with the components.
When placing screws to secure the motherboard to the chassis, please do not over-
•
tighten the screws! Doing so may damage the motherboard.

2.1 Installing Memory Modules (SO-DIMM)
is motherboard provides two 204-pin DDR3/DDR3L (Double Data Rate 3) SO-
DIMM slots. If only one SO-DIMM module is installed, please install it into DDR3_
A1.
It is not allowed to install a DDR or DDR2 memory module into a DDR3/DDR3L
slot; otherwise, this motherboard and SO-DIMM may be d amaged.
e SO-DIMM only ts in one cor rect orientation. It w ill cau se permanent damage
to the motherboard and the SO -DIMM if you force the SO-DIM M into the slot at

2.3 Jumpers Setup
e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper
is “Open”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”
when a jumper cap is placed on these 2 pins.
Clear CMOS Jumper
(CLRCMOS1)
(see p.5, No. 15)
CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear
the CMOS right aer you update the BIOS. If you need to clear the CMOS when
you just nish updating the BIOS, you must boot up the system rst, and then shut
it down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed.
Clear CMOSDefault
Q1900DC-ITX
If you clear the CMOS, the case open may be detec ted. Please adjust the BIOS option
“Clear Status” to clear the record of previou s chassis intrusion status.
