This motherboard provides six 240-pin DDR3 (Double Data Rate 3) DIMM slots, and
supports Triple Channel Memory Technology. For triple 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 identi-
cal DDR3 DIMM pair in Triple Channel (DDR3_A1, DDR3_B1 and DDR3_C1; White
slots; see p.2 No.7), or identical DDR3 DIMM pair in Triple Channel (DDR3_A2,
DDR3_B2 and DDR3_C2; Blue slots; see p.2 No.12), so that Triple Channel
Memory Technology can be activated. This motherboard also allows you to
install six DDR3 DIMMs for triple channel configuration, and please install iden-
tical DDR3 DIMMs in all six slots.

1. Please install the memory module into the white slot (DDR3_A1,
DDR3_B1 or DDR3_C1) for the first priority.
2. Due to Intel
one DIMM is installed into DDR3_A2, DDR3_B2 or DDR3_C2 slot.
3. Due to Intel
supported for one DIMM per channel only.
4. You may install varying memory sizes in Channel A, Channel B and
Channel C. The system maps the total size of the lower-sized
channel for the dual-channel or triple-channel configuration. Any
excess memory from the higher-sized channel is then mapped for
single-channel operation.
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be
damaged.
