Return M-die kit for A-die?

[dgianstefani]

Most of the ITX A620s looked fine to me. 8-layer fare, comparable to some of the midrange full size stuff. ASRock is doing that PCB sharing thing so the A620I and B650I Lightnings basically are the same. Being newer boards both have a pretty recent QVL with 7200 advertised. Unlike Gigabyte's A620, VRM looked fine for single CCD, 8 x 60A SPS or something. Could have saved enough money to buy a whole separate 2x16 Hynix kit too.

It was the supposed A620 limitations that I didn't want to play the lottery on. No sense in losing performance for no reason other than because AMD said so.

QVL is worth nothing IMO, not even as an indication. 95% of boards have hilariously false "support". Just means they got it to boot with a golden sample CPU. Ircow should be able to confirm this, as do many other reviewers.

4x single rank is different than 4x dual. Last attempt with 4x single, I managed 6200 stable.
Highest I could go with 4x dual is 4800. Both before AGESA 1.0.7

Officially AMD only says 3600 is guarantee to work for either.

in either case your results and mine are 100% not plug n play.

was plug n play for me, timings were set before adding 2nd set only thing I changed was termination to auto and rtt`s, 2 mismatched kits, gskill 60003038F16g and KF560C40BBK2-32.

People dont like to try.....

$660 flagship board...I sure hope it has no issues running 6400

it can be done on lesser boards

My bad, I just forgot to try is all. While I'm at it, let just throw out stability, we don't need that either

 

[Durhamranger]

you assume to much , what stabililty tests would you like to see?, bearing in mind i would have to take my A-die out, to go back to 4 x m-die

Karhu 24 hours.

Even just OCCT, but that's quick and dirty stability testing.

Karhu stable is stable.

You can probably easily take #1 if you submit a y-cruncher 10b score. Competition is good and I want to try again now with post AGESA 1.0.7.

Submit - link and I'll see if I can beat it.

its getting late in the UK, I've just booted back with 4 dimms, i`ll come back tomorrow.....

TBH, I don't think so, especially if you're after the white sticks.

A-die is really for diehard over clockers, and you would really need to be playing @ 1080p to see some results. You'll be lucky to get 1fps @ 4k going from 6k-8k MT/s.

Edit: We need @ir_cow he will know

I recently bought Flare X5 6000 CL30-38-38-96 1.35V 32GB (2x16GB) EXPO and the label says: "0R48KXS825A".
Is this Hynix? If so, M-Die or A-Die?

Same ol' A die, but I've never seen revision digit go up that high (5) before

Does this revision date have any significance?
Production date - January 2024

I don't think so, both kits I bought this week were January 2024. G.skill has regularly been using xx20 and xx21 interchangeably for Hynix for years. Maybe they just need more numbers now, lol. The only IC vendor I've ever seen always stick to a xxx0 last digit is Samsung for whatever reason, happened on DDR4 and now apparently DDR5 too.

I bought 2 x F5-6000J3040G32GX2-TZ5N 6000 30-40-40-96 kits and they're both Hynix M-die.

I thought Hynix M-die was EOL on 2x32GB kits?

 

[ir_cow]

@andersmoi how do you know it's really 2GB M-Die? I wonder if the code is wrong. But M isn't EOL as far as I know.

M at the ends means M-die, always with G.Skill.

Hmm that's weird, then how come my apparent A-die finishes with M? Does this mean I have M-die?

24gb is M-die. To my knownledge there is no 24gb A-die

Yes, looks like your right: G.SKILL Trident Z5 RGB DDR5-7200 CL36 2x 24 GB Review - A Closer Look | TechPowerUp

Damn thought I had A-die

Edit: looks like these 2x24GB M-die are good clockers though so will probably stick with them.

24gb M-die is very good. They need a bit more relaxed timings vs A-die, but clocks better.

Sorry for a slight thread hijack, but what is the go-to manufacturer for DDR5 memory currently? I remember Samsung being very sought after for DDR4, but apparently not for DDR5.

Hynix is king of DDR5. They have the 4 top dies. M16gb, A16gb, A8gb and M24gb. They can run much lower RFC than Samsung and Micron which gives them up to 5% more performance. M24gb is capable of running 10GHz+, far above Samsung and Micron.

Hynix and only Hynix. Samsung never figured out how to pass 6400 yet and Micron has super super loose timings.

 

[ThrashZone]

I was originally planning on getting the A620I Lightning to save a buck. But the order ran into some issues and the rear I/O is also REALLY lacking, so the B650E will have to do. Not incredibly enthused about $350, but it's about the same as my AM4 Strix ITX was so (the one about to receive the handmedown 5800X3D)...



I mean, yes, but for a couple years now that's only used to refer to 4 ranks per channel, because everyone and their mother running DR B-die would have been "quad rank" which wasn't the case

Anyways thanks everybody for the help. Got the A-die.

Well, I guess some of these modules are in my future then. Probably two 32GB A-die ones. The markup for the 48GB M-die ones (twice the price of a 32GB) seems too steep. And yes, I exclusively run ECC memory, which makes getting memory a bit harder. Thanks again for enlightening me!

I don't think Hynix or not even matters then...why overpay? Just get the cheapest trustworthy ECC there is.

If you want ECC, your destiny is bare JEDEC spec and nothing else, for reliability. Looks like 5600CL46 is the best you're getting, and just about anything could do that. Same deal as with DDR4 ECC (with the very rare exception of some super late production Mushkin XMP 3600 kits that are still very mediocre on performance).

Like, the reason to choose Hynix M/A here (AMD) is the potential for 6000CL30 and OC beyond, as opposed to topping out at something like 6000CL36 or 5600CL40. Anything faster than JEDEC spec 4800CL40-5600CL46 is also OC, and antithetical to the whole point of ECC. Surely you can tell that these JEDEC ECC spec are all far slower than even non-Hynix XMP

I appreciate what you're saying. Those Kingston ServerPremier modules are some of the cheapest you can get and they're relatively easy to get. That they come with apparent grade A dies from Hynix is just an added bonus.

That said, I really shouldn't hijack this thread any more than this. People already have been more than indulgent.
