Installation
3-3 System Memory Configuration
The mainboard accommodates four
•Supports up to 4GB of 400/533/667MHz DDR2 SDRAM (2GB and 400/ 533MHz for i945PL chipset support only).
•Supports dual channel memory interface.
•Supports
•SPD (Serial Presence Detect) scheme for DIMM detection support.
•Supports configurations defined in the JEDEC DDR2 DIMM specification only.
Dual Channel interface:
•Dual channel memory access offers increased system performance. <Figure 6> shows the logical memory layout for channel A and channel B.
•For dual channel to operate, both channel must be populated with same amount of memory, preferably of the same type.
(Optional)
<Figure 6>
•The four DIMM sockets are divided into two colors to help you identify the channel pairs <Figure 7>. Each dual channel pair has the same color, e.g. DIMM1 and DIMM3. To obtain best performance, simply mount DIMM sockets of the same color.
