: Dual-Channel RAM in computers

870 views

I recently found out that I had my 2 RAM sticks in apparently a ‘wrong position’ (side-by-side).
Someone pointed out that they needed to be placed in alternate slots.
I read my motherboard manual, I tried doing as much research as possible about this but all I got from that is that the alternate placement puts the RAM in ‘dual-channel’ mode and is somehow better.

I haven’t got any clear-cut/simple explanations as to WHAT ‘dual-channel memory’ means or WHY it’s better.

Someone please ELI5.

Besides saying “it’s faster” like this is ELI2 or something, the actual reason it’s faster that could be understood by a five year old is as follows:

RAM has Memory and Speed. Memory is how much work it can do, and Speed is, well, how fast it can do that work. It’s much easier to increase Memory (4/8/16/32 GB) than it is to increase speed (2000mhz~3200MHz). If you only have the option of one 32GB/2500 MHz or two 16GB/2200MHz for example, the two would be better if your motherboard supports dual-channel. With dual channel, it can use both at the same time, effectively making the two 32GB/4400MHz.
