This article is very useful to people especially when they need to compare which
RAM to buy and the information provided in this article is certainly needed to make their decision right.

P.S. Since more higher DDR2 is/are introduced to the market, please add their
clock tick duration per cycle to your current list.. Thank you.

Nice article. Perhaps it needs a little updating?

Thanks for the much needed update!

Now, if it only included some additional info about the difference between "plain" DDRx and GDDRx...

Cheers

Nice article, I've learned something new, thanks!

PS.
On page 3:
"Typically DDR memories are fed with 2.5 V, DDR2 memories are fed with 1.8 V and DDR2 memories are fed with 1.5 V"

I think it should be DDR3

I knew I'd seen it somewhere...

Still, adding a small note that the "G" prefix generally means "Factory over-volted and over-clocked." doesn't require much typing and saves the reader a search for that four years old article...
