Ryzen 3000-series and Samsung A-die...

[Mr.Meerkat]

Hey all, what's everyone's experience with Samsung A-die and Ryzen (specifically 3000-series or even more specific, 3700X)? 

 

Recently went from a set of 2x8GB 3200MHz Micron Rev.E to 2x16GB A-die 3200MHz kit. Sadly, couldn't find any 2x16GB non A-die kits (that weren't £150-200) so went for some LPX. Annoyingly, it's not stable with the 3200MHz XMP profile or 3000, 2933 or even 2800MHz. Gave up for now so it's sitting at 2133MHz, which is at least stable (but is less than ideal when an 8 year old kit can run at a higher speed).

 

I guess it's just feels a bit weird when your set of dinosaur Micron 8Gbit Rev.A would be happy overclocked at 2933/CL16 (99% stability, was happier at 2800MHz) meanwhile the Rev.E kit happily sat at 3600/CL15.

For reference, this is with AEGSA V2 1.2.0.7

Not all cas 16 is created equal. Zen2 is supposed to be not that caring of nonQVL memory but that doesn’t seem to be true in this case.  I’m wondering what the other three numbers are on that cas16.  Memory makers have been scamming users lately with “cas16” stuff that is effectively cas20 or even 22.  You may have gotten some of that.

When I was running 3700xI bought 3000Mhz cas 16 and ran that stuff 3200Mhz cas 14 (don't ask about voltage) that $*** ran stable

While that doesn't answer your question directly, i don't understand why you didn't go 3200 trident Z? there are really cheap kits (around 100 iirc) and i think they're pretty much guaranteed to work, no matter the "die".

Myself I’ve had a hard time finding that without rgb stupidity on it.  The trick these days seems to be finding decent memory that isn’t like an inch and a half tall with rgb idiocy on the top.  Maybe buy some and rip the plastic “heat sink” off so it will fit in a computer with a decent sized air cooler.

As bomb has mentioned, there's the RGB issue (SFF build so height does matter) and also, they were £140 kits at the time. For maybe £10 more, I could have just went for some binned B-die kits (or even "old-new stock" 4000MHz Ballstix Max for £20 more) 

 

And for reference, I picked the 2x16GB LPX up for £55. I mean I was fully expecting A-die to be worse but come on, at least it should be able to run at XMP speeds. I guess there was also the off chance that it had been sitting in a warehouse for a while and would actually be micron Rev.B or E.
