Hi, one of my bad memory sticks might be replaced and I was wondering how do the different memory banks work? Do they have separate memory controllers for each and can they run at different speeds and timings? On my Gigabyte mobo, you put two memories in the first two slots, but I think they're going in different banks so bank 1 is slot 1 and 3 and bank 2 is slot 2 and 4. Would I be able to run just 3 memories at one time too? And if I'm stuck with two different memories, would it have to run at the pace of the slowest one? Thanks in advance for your replies.
