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.
17. 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.

This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR3 DIMM pair in the slots of the same color. In other words, you have to install
identical DDR3 DIMM pair in Dual Channel A (DDR3_A1 and DDR3_B1; Blue
slots; see p.2 No.7) or identical DDR3 DIMM pair in Dual Channel B (DDR3_A2
and DDR3_B2; White slots; see p.2 No.8), so that Dual Channel Memory Technol-
ogy can be activated. This motherboard also allows you to install four DDR3 DIMMs
for dual channel configuration, and please install identical DDR3 DIMMs in all four
slots. You may refer to the Dual Channel Memory Configuration Table below.
Dual Channel Memory Configurations

(2) - - Populated Populated
(3)* Populated Populated Populated Populated
* For the configuration (3), please install identical DDR3 DIMMs in all four slots.
1. If you want to install two memory modules, for optimal compatibil-
ity and reliability, it is recommended to install them in the slots of
the same color. In other words, install them either in the set of blue
slots (DDR3_A1 and DDR3_B1), or in the set of white slots
(DDR3_A2 and DDR3_B2).
2. If only one memory module or three memory modules are in-
stalled in the DDR3 DIMM slots on this motherboard, it is unable to
activate the Dual Channel Memory Technology.
3. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
4. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be
damaged.
5. If you adopt DDR3 1600 memory modules on this motherboard, it
is recommended to install them on DDR3_A2 and DDR3_B2 slots.
