Yeah, I'd actually love to see some real-world testing to back this up. Are the tertiary sub-timings so important that if you copy them from one module onto another module, the whole system is buggered?
I've heard this "advice" for about 15 years, but I've never seen it backed up with data. But, I've only built a handful of systems and never had the opportunity to mix RAM, :(
This is purely anecdotal but last year I built a system with a dual-channel G.Skill kit, and half the time it wouldn't boot or if it did boot, it would hang right after POST. I swapped both G.Skill modules with a couple of random modules I had laying around, and the board booted and ran fine. I then swapped one of each G.Skill module with one of the random modules, still booted fine. It was *only* when both G.Skill modules were present that it had issues. I ended up sending those back for a Crucial dual channel set that worked fine, though it was less aggressively timed (which was fine since this was a workstation build and not a gaming rig).
Well, they always say that about memory but I guess it's more of a case if you're running highly OCed memory and stressing the memory controller.
I've had (anecdotal experience, I know), for years and years, used on 3 AMD desktops and one Intel two kits of the same maker/model to reach the amount of RAM I wanted, but none of these are overclocked pieces (topped out at DDR2-800 C4 and DDR3-1600 C8) and just use XMP profiles.
If I was going to build a more "critical" system tho, I'd probably look at using a single kit... not hard to get decent 16GB or even 32GB kits now with just 2 modules.
As a side note, I notice that Micron's 8Gbit die revision A was quickly replaced by revision B. I think revision A is 25nm and revision B is 20nm, right?

>The prices of the dual module kits are slightly above buying two single modulestechnically, you are right )))

Thanks for the explanation about different timings on multi-module kits. To this day I had no idea that was done.mczak - Wednesday, May 18, 2016 - link
I don't believe that explanation for half a second.ikjadoon - Wednesday, May 18, 2016 - link

Why the freak out? The price premium of a dual module kit over 2 single modules is 1 cent here.surt - Thursday, May 19, 2016 - link
It's almost 3 ten-thousandths of a dollar per GB!yuhong - Friday, May 20, 2016 - link

Not bad, not bad. I read recently https://alin.or.ke/betting-apps-in-kenya/ about using it in sports betting. Very interesting that you catch that vibe too.Marrie Hill - Thursday, January 13, 2022 - link
