Old MBP memory to new MBP

[mrtrilby]

I have a week old early 2008 MBP that I've put 4GB of DDR2 memory in. I'm returning it to Apple though to swap for a late 2008 model MBP.

Can I put the DDR2 memory out of my old one into the new? I'm not fussed about a small performance loss, but I wouldn't mind avoiding re-buying 4GB of RAM so soon. I plan to put 6GB (or 8GB if Apple enable it somehow) in once DDR3 prices have dropped a little.

Will it work?

DDR2 and DDR3 run at significantly different voltages. I doubt it would work. Your best option is most likely to sell your ram and either wait until DDR3 comes down in price (happening as we speak), or buy some DDR3 now.

DDR2 and DDR3 run at significantly different voltages.

The number of pins is different as well. The two are not compatible.
