Hi, I have a question about how the dual channel works, I'll give you an example

the cpu needs the information ''number''1 and ''number'' 10, with dual chanel activated with two equal memories, one ram module will send the information '' number''1 and the other will send information '' number '' 10? or not, module one will send information 1 and 10 and module 2 will do the same thing by sending information 1 and 10?

The system treats it as one big pool of RAM.
but in this matter when the information is passed with dual chanel, like cpu needs information do the 2 ram modules divide the work each one sending a part or the two send the same part?

Gulps......the cpu wants 16bytes.....128 bits.
In single channel the first gulp is 64 bits.
The second gulp is 64 bits.
Two gulps.

In dual channel the first gulp is 128 bits.
One gulp.

I used these numbers to identify that they are information type, like information 1 and 10
The above is a good representation. So how many bits do your numbers "1" and "10" require? Are they ASCII? Are they integers? If so how many bits? 32 is common, but you could have a 16bit integer. Are they floating point? 64 or 128 bits are common for floating point.
There is no single answer.
Your "numbers" may have already been fetched into the CPU cache because of another adjacent fetch. They might be in CPU cache and the main RAM is not accessed.
