That's cutting the bandwidth in half. 

It doesn't work this way.

I mean spit it into 2 sticks is cutting it in half, instead the full speed goes to one slots. Isn't that better?

But is it is hard to manage for now, I guess I can accept that but should be able to conquer that.

instead; ----------------------------lane 1------ stick 1(higher performance take full capacity of the lane)

Therein could be the problem... limited PCI-e lanes.

Nothing that runs Windows or x86 is set up the way you're thinking.

Conquer what?

Now that I think about it, makes sense. I would propose double side lanes to mitigate that. 

Always thought it would save space by removing the second dimm(because less space taken)then you can put more lanes at least some.

Like if 16gb in one lane performe same as 2x8 gb then there is no need for second channel.

It never did... that's why we have the way things are set up the way they are.

Confuses me this answer.

Like if 16gb in one lane performe same as 2x8 gb then there is no need for second dimm in the same bandwidth capacity.

Conquer the technical problems of 1 dimm/channel at same speed.

But it doesn't work that way. 

The ram has nothing to do with the lanes. 

They are on a lane connected to a memory channel on the cpu!

It's not a problem and it's not a technical problem. It never was and no one complained about it.

Just wondering, not complaining. Numbers jsut for show.

Still wouldn't it be better if lets say duan channel, 2x2gb am@1600mhz x2 be replaced by 1x4gb@3200mhz x2. So 4 stick 2 channels first one, then 2 channels 2 sticks second one. Completely eliminated the secondary dimm slot in the channel so we could have a larger heat sink or die space or else. Maybe it will help you understand what I meant.

[We Didnt_t start_the_fire]

For better understanding:

Numbers are just for show.

i.e      ----------------10gbps--------------lane 1------5gbps---- stick 1

                                                                       l

                                                                    ------5gbps---- stick 2

 

instead; -------------10gbps---------------lane 1------10gbps----- stick 1(higher performance take full capacity of the lane)(should be possible to double performance of DDR)

 

I.e use case; 2x2gb am@1600mhz x2 be replaced by 1x4gb@3200mhz x2. So 4 stick 2 channels first one, then 2 channels 2 sticks second one. Completely eliminated the secondary dimm slot in the channel so we could have a larger heat sink or die space or else. Maybe it will help you understand what I meant.

 

And save the extra space for a second(or extra) channel/lane or other things such as larger die seize or heat pipes or other things. 

Each stick have iit's own lane.

First of all. 

There is no 2 gig ddr4 sticks 

2nd of all. 

1600 Is the same as 3200.

Numbers just for show and I am well aware it is double rate data.

Either. 

It wouldn't work as 1 stick occupies one channel so no it wouldn't work.

Why? Reasons? I am trying to understand it and that was my original question.

Because let's say you have an am4 cpu

That has 2 memory channels alright ? 

Let's say you have 2 sticks. 

1 stick will go to one channel and the other to the other channel. 

You can't jam two stick together so they can get one. That would just make it one stick and that will occupy one channel. 

It really is simple. 

(Memory channel) |←ram1

(Memory channel) | ← ram2

OK.....so the A2/B2 is only for capacity? Assuming we are talking am4 dual channel have 4 dimm slot.

A2/B2 are dimms that are connected to the memory channel basically

No.

Any consumer platform will have 2 memory channels and will one for each stick if it's dual and 1 channel for 2 stick if it's quad stick.

That clears it up for me mostly.

That's what I am wondering, because I have a quad stick mobo and wondering why don't make it quad channel with each stick have one channel. 

If it is because ram are too slow to saturate the channel, then make them better. Basically save the space for other things.

Because these features are reserved for high end HEDT/ server chips.

I never dealed or looked at mobo with only 2 slots stick, just looked at A320s on newegg. That clears some confusion. 

But I do like it not necessarily to be minimal but don't over crowd. I did go for 2x16GB instead of 4x8 GB. So that is the angle where I came from.
