939N68PV-GLAN

motherboard provides four 184-pin DDR (Double Data Rate) 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)
DDR DIMM pair in the slots of the same color. In other words, you have to install
identical

DDR DIMM pair in Dual Channel A (DDR1 and DDR2; Blue slots; see p.

10 No.7) or identical DDR DIMM pair in Dual Channel B (DDR3 and DDR4; Black
slots; see p.10 No.8), so that Dual Channel Memory Technology can be activated.
This motherboard also allows you to install four DDR DIMMs for dual channel
configuration, and please install identical DDR DIMMs in all four slots. You may
refer to the Dual Channel Memory Configuration Table below.

For the configuration (3), please install identical DDR 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 (DDR1 and DDR2), or in the set of black slots (DDR3 and
DDR4).

2. If only one memory module or three memory modules are in-

stalled in the DDR 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 DDR1
and DDR3, it is unable to activate the Dual Channel Memory Tech-
nology .
