*Core 2 Duo with Santa Rosa* - Maximum Ram that can be installed 4GB, Maximum Ram it will use 4GB *Core 2 Duo* - Maximum Ram that can be installed 4GB, Maximum Ram it will use 3GB (with a slight increase to 3.2GB for matched pairs) *Core Duo* - Maximum Ram that can be installed 2GB, Maximum Ram it will use 2GB Sorry to double post but after some reading, I conclude the following: The maximum number of devices per SO-DIMM is 16.Īccording to that because of the 1GB limit per module, 2GB is the maximum. The width of each 667 MHz memory bus is 64 bits.

However, because the memory in the two slots is configured as a contiguous array of memory, both SO-DIMMs must be the same size and type for the interleaving function to be used to improve performance. The memory controller supports 256 MB, 512 MB, and 1GB SO-DIMMs. The largest capacity SO-DIMM supported is 1 GB, so the maximum memory capacity is 2 GB. The 2.0 GHz computer ships with two 512 MB DDR2 SDRAM SO-DIMMs for a total of 1 GB. The 1.83 GHz computer ships with two 256 MB DDR2 SDRAM SO-DIMMs for a total of 512 MB. The SO-DIMMs must be DDR2-667 (PC2-5300) compliant and must be unbuffered, unregistered, 8-byte, nonparity, and non-ECC. The MacBook computer introduced in November 2006, based on the Intel Core 2 Duo, provides two RAM slots that accommodate 200-pin DDR2 SDRAM SO-DIMMs up to 1.25” in height.
