Installation
3-3 System Memory Configuration
The mainboard accommodates four 240-pin DDR2 DIMM sockets.
•
Supports up to 4GB of 400/533/667MHz DDR2 SDRAM
533MHz for i945PL chipset support only).
•
Supports dual channel memory interface.
•
Supports non-ECC memory and non-Registered DIMMs only.
•
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.
• 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.
