Can older MacBooks have uneven memory?

[Durbrow]

I would like to upgrade an older MacBook Core Duo from 512 MB to 1.5 GB of memory using memory from my old MacBook Pro. Two questions:

1. Can MacBook take MacBook Pro memory? The speed of the memory appears the same.

2. Can the MacBook have an unbalanced memory allotment? I.e., 1 GB in one slot and 512 MB in another?

Many thanks!

1. Yes, in most cases (it depends on what version of MacBook you're trying to put the RAM in, taken from what version of MacBook Pro).

2. Yes. You should check on maximum memory specs for the specific model you're upgrading, though, so you don't try and put a 1GB and a 2GB stick into a computer that can only use 2GB.
