'Intel optimised' vs 'AMD optimised' - does it mean anything?

Not sure what has been optimised, but I can tell you from my actual experience; I have some Corsair DDR5 5600Mhz C36 RAM that's Intel Optimised. And I have them running fine in my AMD 7950X system. So... *shrug*
If what I remembered was right, the AMD EXPO, has a few more details about the RAM its on included, allowing the AMD CPU to fiddle around a few more settings whilst memory training for more performance out of them potentially. These EXPO details don't mean anything to the Intel IMC when they read it and so ignored. Otherwise, they should be fine for use in either system.
Using old memory is fine in any system (Intel or AMD) so long as they support that RAM type. The only thing is, much like any RAM normally, mixing mismatched (frequency, timing, etc) sets can cause performance loss and instability.

Good to know, thank you!

I believe I read somewhere that AMD is a bit more fussy what mem kit it's paired up with, occasionally a compatibility issue shows up.
Certainly had a case like this with an older Ryzen 3100 system I built and the memory kit I got for it wasn't on the mobo compatibility list.
Darn thing didn't even want to post. Swapped the kit for a different set (was on the list) and things were alive and proper.

Interesting. What I currently have is 2x16 of ddr4 3200, specifically selected to work with Ryzen 1 (so Samsung B-die) because they were legendarily fussy if you wanted to get that speed. It's been running with an 8700k for the past 3.5 years. Thinking about it, never tried overclocking the memory, maybe I should have!
But I probably wouldn't really want to reuse these sticks, I'd be more likely to get 2x32 of something else. Sounds like choosing AMD optimised could be the safer bet, should those wind up in a different system 2 years down the line...

I think they're trying to guide people into sensible choices rather than there being any real optimisation.

Unless someone in the Amd or Intel lab actually sat down and tried it with a bunch of hardware to prove its optimised.. That would be an interesting concept I can't see happening
Perhaps different way tound, they could be sending cpus to mem manufacturers who to earn the badge must do some testing.. Now, that to me sounds more plausible..
