775XFire-eSATA2 motherboard provides four 240-pin DDRII (Double Data Rate
II) 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) DDRII DIMM pair in the slots of the same color. In other words,
you have to install identical DDRII DIMM pair in Dual Channel A (DDRII_1 and
DDRII_3; Yellow slots; see p.2 No.7) or identical DDRII DIMM pair in Dual Chan-
nel B (DDRII_2 and DDRII_4; Orange slots; see p.2 No.8), so that Dual Channel
Memory Technology can be activated. This motherboard also allows you to
install four DDRII DIMMs for dual channel configuration, and please install iden-
tical DDRII DIMMs in all four slots. You may refer to the Dual Channel Memory
Configuration Table below.

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 yellow
slots (DDRII_1 and DDRII_3), or in the set of orange slots (DDRII_2
and DDRII_4).
2.
If only one memory module or three memory modules are installed
in the DDRII 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 DDRII_1
and DDRII_2, it is unable to activate the Dual Channel Memory
Technology .
4.
It is not allowed to install a DDR memory module into DDRII slot;
otherwise, this motherboard and DIMM may be damaged.
