Forgive my ignorance...
What's the difference between SDRAM and DDR RAM? And this is the stupider question: can I use the 1Gig of SDRAM I have in my current G4 in the new PowerMacs with DDR RAM? Of course I would be expecting RAM performance decreases, but would I have to just kiss the current 512MB chips I have in my current machine goodbye?

Okay, your forgiven
Although I'm no ram expert, I'd say definatley, no. The difference between them? Don't know on a technical level, but DDR is apparently significantly faster.

Double the speed actually: Double Data Rate RAM

Hope I explained this correctly...does this make sense to you?
I know what it means just not sure how to explain it.
On the upside, DDR RAM transfers two bits on every clock cycle rather than one as in SDRAM. This means the bandwidth to/from memory is doubled, which will make a huge difference in processor intensive applications -- especially in all AltiVec code since the AltiVec usually spends its time waiting for memory.
