Well now, it's fairly obvious that DDR2 RAM is better, but I still have a question that will hopefully be very easy to answer.

I've gotten my hands on an old computer that only takes DDR RAM. This is unfortunate, because I also have four spare 1GB sticks of DDR2 RAM. I've been thinking of trading the four 1GB DDR sticks for four 1GB DDR2 sticks. I figure there will be plenty of people willing to take advantage of this trade.

But I'm wondering: how does 1GB of DDR RAM compare to 1GB of DDR2 RAM? Is one gig of DDR2 RAM more effective than one gig of DDR RAM? Or does the advantage of DDR2 RAM come solely from the fact that you can get sticks bigger than 1GB?

Naturally, I can't choose between the two without switching motherboards. But I'm curious how the two types compare to each other on a level playing field. Wikipedia didn't seem to answer this specific question.

It depends on what they want.
If there computer uses DDR ram they will not be interested

DDR has 184 pins

DDR2 has 240pins

and the position of the notch is different.

The default voltage is different.

The pin issue is different on notebook ram ie SODIMM they both have 200pins

In simple terms DDR2 has a faster read write speed in essence twice the speed of DDR

Thanks for the link! I will read it.

But in short, it sounds like 1GB of DDR2 RAM is about as fast as 2GB of DDR RAM?

And yes, I realize you have to conform to what your motherboard can take. I just figured that if someone were to get a new computer that takes DDR2 RAM, they might like the chance to trade their old computer's DDR RAM so they won't have to buy as much DDR2 RAM. If they're in a position similar to mine, they might be wanting to dismantle their old computer to salvage the parts.

Well I suppose they might.

After thinking about how memory is stored and accessed, I can understand how that might not be possible to quantify, since the retrieval process would be slightly different in every circumstance. But still, the information has been quite useful. Thank you!
