Old memory in new MacBooks

[Craigy]

I am going to sell our 6month old macbook to get a new one. It has 4Gb of 667 in it - can I use this memory in the new macbooks even though the new ones have faster chips?

 

[Scarlet Fever]

i wouldn't think so.

you'd be hurting the speed and since it's ddr2 v. ddr3 I don't even think that it would work.

No. The old ones use DDR2 and the new ones DDR3 - there is no interchangeability between the two.

No, I don't think you can. The old DDR2 runs on a different voltage than the newer DDR3 (1.8 vs. 1.5).
