Random ram question

[Ripred]

I came across a bunch of videos explaining the downsizes of mixing ram kits and it occurred to me, if you were in a situation whatever it is where you had to mix kits, would you get better results with each kit on there own channel or one stick from each on each channel.

I'm mildly interested if this has been tested already,if there is any difference at all

Whenever I've mixed RAM kits, I've always put them one stick per kit per channel. This has always seemed like a sensible idea, although I've never done extensive testing of the effects of going the other way around.

 

And honestly, I've never had any issues, going all the way back to the SDRAM days before DDR, putting a 256MB 133MHz stick in slot A and a 128MB 133MHz stick in slot B for an old Pentium 4 system, I've never had a problem with mixing RAM. It has always worked for every system I've upgraded.

 

However, I've never tried to use RAM well above the officially supported speeds. By that I mean, that I was okay with dropping to DDR-333 speeds on an old system in spite of one kit being DDR-400, and I didn't fight it. And today, with my current system, I'm only running DDR4-3200, which is the official supported spec for the 5900X. So even though the RAM is mixed, it's not like I'm stressing out the IMC that much. Whereas if you try running DDR4-4000, good luck getting it to work with more than 2 sticks.
