Do memory channels really matter?

I always thought that memory wouldn't work if it was used "out of channel" (you can tell i know what I'm talking about can't you). However recent expeireince has shown that it is possible. Is it worth it for the extra prices of brand new RAM. Thoughts?

...out of channel...

?

is this a single vs dual channel question ?

I just wanted to know if you could use two of the same type of RAM modules together, without them specifically being designed to be used together. Without a major performance drop.

It's advisable to use RAM with the same timings. Mhz and latency etc. You can use other RAM, but I think that causes some instability.

What exactly are you trying to do?

set it to the lowest common denominator and your set I've done it on dozens of computers

channels only matter if you want speed. in most cases as long as slot 1 is used you can pick any other slot you want and the mode changes accordingly.

in general slots:

1+3=dual channel

1+2=single  channel

1+2+3=single channel

1+2+4=single channel

all slots used= dual channel.

 

in some older motherboards you need identical pairs to use dual channel but intel made a Flex mode so boards made after 2008 (I think maybe earlier) can mix and match ram. that said ram in flex mode isn't as fast as dual channel but it is faster then single channel.
