Resolved Memory

[chattahoochee]

Instructions stat that both memory cards must be identical, does this mean, if I choose to place a 2 Gb card in one slot & leave the 1 Gb card in the other the system will not recognize the 2 Gb card ? I have ordered a 2 Gb card, I currently have two 1 Gb cards installed. Checking the MacBook using the serial number, it states the max memory at 4 Gb.

In Macbooks you can have different size memory sticks. But they won't run in dual channel mode so it'll be slightly slower in accessing the memory.

OK, I'll install two 2Gb memory sticks.

Where did you check the maximum amount with your serial number? I just ask, as Apple is known to not state the actual maximum of RAM for their Macs.

PS: Gb is short for Gigabit, GB is short for GigaByte, and 1 B = 8 b.

From his previous posts I saw he has a 2006 MB. The question of which version he has would tell us if the max is 2GB or 4GB.
