Dual Channel ( One more question)

[Gary]

I've read a bit about "dual channels" usually when talking about
memory ( I think ) I was wondering if someone could explain it or
direct me to a URL where I can read up on it.

Thanks in advance

The short answer...

The memory bus can only go so fast and is often a bottleneck in the
speed. For example, it may be able to move data in an out of memory at
400 MHz.

Someone had the idea that if we could move one chunk of data through the
bus to one piece of memory at 400 MHz, why don't we move every other
chunk of memory into two different piece of memory. That way we don't
have to wait for the bus to keep up. Therefore, we use two piece of
memory at 400 MHz each to simulate 800 MHz of real speed. You just need
something to control all that.

So, Dual Channel memory is splitting the memory access between two
physical pieces of memory to increase throughput to about double of what
the bus will allow.

but in the real life, there is not much difference ...
