775i915P-SATA2 motherboard provides four 240-pin DDRII (Double Data Rate)
DIMM slots, two 184-pin DDR (Double Data Rate) DIMM slots, and supports Dual
Channel DDR/DDRII Memory Technology. For dual channel configuration, you
always need to install identical (the same brand, speed, size and chip-type)
DDR/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.6) or identical DDRII DIMM pair in Dual Channel B
(DDRII_2 and DDRII_4; Orange slots; see p.2 No.7), so that Dual Channel Memory
Technology can be activated. You can also install identical DDR DIMM pair in
Dual Channel (DDR1 and DDR2; Blue slots; see p.2 No.8) so that Dual Channel
Memory Technology can be activated.This motherboard also allows you to in-
stall four DDRII DIMMs for dual channel configuration, and please install identi-
cal DDRII DIMMs in all four slots. You may refer to the Dual Channel Memory
Configuration Table below.

For the configuration (3), please install identical DDRII DIMMs in all four DDRII
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 yellow
slots (DDRII_1 and DDRII_3), in the set of orange slots (DDRII_2
and DDRII_4), or in the set of blue slots (DDR1 and DDR2).
2.
If only one memory module or three memory modules are installed
in the DDR/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 DDR into DDRII slot or DDRII into DDR
slot; otherwise, this motherboard and DIMM may be damaged.
5.
It is not allowed to install both DDR and DDRII to this motherboard
at the same time; otherwise, this motherboard and DIMM may be
damaged.
