3-3 System Memory Configuration
The mainboard accommodates four 240-pin DDR2 DIMM sockets.
• Supports up to 4.0GB of 400/533MHz DDR2 SDRAM.
• Supports
dual channel memory interface.
• Supports non-ECC memory and non-Registered DIMMs only.
• Supports 256Mb/512Mb/1Gb DDR2 technologies in x8 and x16 devices 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.
• 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
DIMM1 and DIMM3. To obtain best performance, simply mount DIMM
sockets of the same color.
