Memory controllers used to be on the motherboards. So your motherboard would determine the type of RAM you used.
As you may know the something called the chipset these days they used to be called south bridges and we had a north bridge. And the North bridge had things like Memory Controller and other IO stuff. South Bridge hasn’t changed much in terms of what it does. More IO.
It’s basically like cache tiers. The closer you are to the CPU the faster you can be.
