Why is dual channel memory better?

What are the benefits of dual channel memory?

[Glenwing]

Doubles memory bandwidth. Running 2400 MT/s memory in dual channel is effectively the same as 4800 MT/s in terms of bandwidth.

[Jurrunio]

in theory twice the bandwidth

I'm with the bandwidthwagon on this one

When you have two sticks working in Dual Channel what's happening is that they fill up proportionately so if you're using 4gb you have 2gb in each stick.

 

So you have two places to draw the data from.

Think of it like this

 

 

| <— that is Fred, he is a 4gb stick of ddr4 ram

| <— this is his co worker, also a 4gb stick

 

fred gets stuff done on his own

so does his co worker

 

but when they start working together, they do it twice as fast (more or less)

don't forget the 15 minute breaks.

It increases bandwidth. Very important for some applications.

I've heard that Intel doesn't benefit nearly as much as AMD does from the dual channel, but I'm sure it's a benefit either way.

 

While we are here, I have heard people suggest high capacity dual channel over med capacity quad channel. Anybody know why that might be?

Maybe their needs (Rendering/Heavy loads/Databases) require or use the different configs to their strengths...
