Sorry to be a bit off topic but, in here is where all the brains are :-)

Can ayone in here point to link or two that explain dual channel boards
that, to all intents and purposes have 2 memory controllers, which used to
be called a "memory interleave" or "memory paging" function or something
like that, and which would come into 'play' on a board that had that feature
on it, years and years ago, when the correct memory type and confiuration
was used. e.g.
http://www.digit-life.com/articles2/...-1vs2channels/ but, ones that
explain it in English and perhaps, cover ddram and how both edges of the
memory clock cycle carry data, so giving increased peak burst data
transfers, compared to non-ddr memory, and how dual channel improves memory
performance a little. Of course nowadays we're hit with lots of crap from
the advertising industry about "matched memory modules."

I was talking to a young chap at work who was proudly telling me about his
PC with an XP3000, I think he said he had in it, he didn't seem to know what
type of motherboard he had in it - he knew it had 512mb ddr333 memory in it.
I asked if it was a dual channel board, and (bless his little heart), he
seemed to think that "double data rate" and "dual channel" were the same
thing.

If anybody could point to a url with the two features described, and
perhaps contrasted in some way, I'd like to print it out for him.
