Development Kit Hardware Features—Intel Core 2 Duo Processor and Intel Q35 Express Chipset
• Non-ECC DDR2 (667/800)
• 512Mb, 1Gb and 2Gb technology
• 4 DIMMs, 4GB maximum per channel, 8GB total memory
• Dual channel (Interleaved) mode. This mode offers the highest throughput for real
world applications. Dual channel mode is enabled when the installed memory
capacities of both DIMM channels are equal. Technology and device width can vary
from one channel to the other but the installed memory capacity for each channel
must be equal. If different speed DIMMs is used between channels, the slowest
memory timing will be used.
• Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs is
used between channels, the slowest memory timing will be used.
Figure 3 illustrates the memory channel and DIMM configuration.
2.5.1 Dual Channel (Interleaved) Mode Configurations
Figure 4 shows a dual channel configuration using two DIMMs. In this example, the
DIMM 0 sockets of both channels are populated with identical DIMMs.
