2.5 Installation of Memory Modules (DIMM)

775Dual-880Pro motherboard provides two 184-pin DDR (Double Data Rate)

DIMM slots and two 240-pin DDRII DIMM slots, and supports Dual Channel Memory

Technology. For dual channel configuration, you always need to install identi-

cal (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 (DDRII1 and DDRII2; Yellow slots; see p.12 No.6) or identical DDR

DIMM pair in Dual Channel B (DDR1 and DDR2; Blue slots; see p.12 No.7), so

that Dual Channel Memory Technology can be activated. You may refer to the
