Fatal1ty Z68 Professional Gen3 Series Motherboard
2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM
slots, and supports Dual Channel Memory Technology. For dual channel con-
fi
guration, 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; Red slots; see p.4 No.4) or
identical
DDR3 DIMM pair in
Dual
Channel B
(DDR3_A2 and DDR3_B2; Black slots; see p.4 No.5), so that Dual
Channel Memory Technology can be activated. This motherboard also allows
you to install four DDR3 DIMMs for dual channel con
fi
guration, and please in-
stall
identical
DDR3 DIMMs in all four slots. You may refer to the Dual Channel
Memory Con
fi
guration Table below.

For the con

guration (3), please install
identical
DDR3 DIMMs in all four
slots.
1. If you want to install two memory modules, for optimal compatibility
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 red slots
(DDR3_A1 and DDR3_B1), or in the set of black slots (DDR3_A2
and DDR3_B2).
2. If only one memory module or three memory modules are installed
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 dam-
aged.
5. Some DDR3 1GB double-sided DIMMs with 16 chips may not work
on this motherboard. It is not recommended to install them on this
motherboard.
