12. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC
system.
13. EuP, stands for Energy Using Product, was a provision regulated by
European Union to define the power consumption for the completed system.
According to EuP, the total AC power of the completed system shall be
under 1.00W in off mode condition. To meet EuP standard, an EuP ready
motherboard and an EuP ready power supply are required. According to
Intel’s suggestion, the EuP ready power supply must meet the standard of
5v standby power efficiency is higher than 50% under 100 mA current
consumption. For EuP ready power supply selection, we recommend you
checking with the power supply manufacturer for more details.

size and chip-type) memory modules in theDDR3 DIMM slots to activate Dual
Channel Memory Technology. Otherwise, it will operate at single channel mode.
1. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot;otherwise, this motherboard and DIMM may be damaged.
2. If you install only one memory module or two non-identical memory
modules, it is unable to activate theDual Channel Memory Technology.

The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose pin1
and pin2 are “Short” when jumper cap is
placed on these 2 pins.

(see p.10, No. 2) +5V_DUAL for USB23/45
wake up events.
Note: To select +5V_DUAL, it requires 2 Amp and higher standby current provided
by power supply. When you select +5V_DUAL, USB devices can wake up
the system under S3 (Suspend to RAM) state.
USB_PWR2 Short pin2, pin3 to enable
(seep.10, No. 20) +5VSB (standby) for
USB6_7/8_9 wake up
events.
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by

Clear CMOS Jumper
(CLRCMOS1)
(seep.10, No. 10)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After 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
after you update the BIOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system first, and then shut it down
before you do the clear-CMOS action.
