775Dual-VSTA 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 / 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_2; Yellow slots; see p.10 No.6) or
identical DDR DIMM pair in Dual Channel B (DDR1 and DDR2; Blue slots; see p.
10 No.7), so that Dual Channel Memory Technology can be activated. You may
refer to the Dual Channel Memory Configuration Table below.
