106007, 4006121R


These are the four memory slots on the motherboard. The slots support the following:

240-pin DDR2 SDRAM Dual Inline Memory Modules (DIMMs)
DDR2 667 or DDR2 533 MHz DIMMs
Memory capacity up to 4 GB total memory


Channel B slots (top pair in this graphic) are closest to the edge of the board, channel A slots (bottom pair in this graphic) are closest to the processor. The color of the release latches on each pair of slots indicates DIMM 0 (white latches) or DIMM 1 (black latches) for the respective channel.

Memory Configurations


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 are used between channels, the slowest memory timing is 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 are used between channels, the slowest memory timing is used.
