Which memory manufacturer is this?

[azrael]

I've (very) recently got some Mushkin Proline ECC DDR4 modules. Mushkin's product code is MPL4E320NF32G28, but it's not apparent who manufactured the actual memory dies. The only thing I can read is 10-1706-37-BA-F (note, the B might be an 8). Perhaps someone here knows...

Does it really look like this? Can you read the part numbers off the chips? Have you tried reading the SPD chip data with Thaiphoon?

That is the only thing I can read on the chips. The modules are still in their packaging. Otherwise I'm sure HWInfo et al could tell me more.

Is it just too small to read? Try taking a good photo and zoom. Also possibly you can paint bucket (flood fill) the image with color and get an outline of the remaining text if the color difference it good enough.

Been there, done that. That's the only reason I know what I know.

Not sure why it matters as long as it works.

That said, I have some old Mushkin DDR3 RAM and just looking at one of the sticks, it appears the actual memory modules (ICs) are made by Micron. While that could mean Mushkin had an agreement with Micron (a common agreement since most RAM brands do not actually make their own chips) that does not mean it was an "exclusive" agreement. Yours might be made by Samsung.

But again, other than just for curiosity, it should not matter.

Curiosity is actually the one and only reason for asking. I'll (probably) find out eventually, but it just irks me that I cannot discern anything useful from the modules themselves.

Meh, it's ECC RAM. Few people have seen these, no website seems to have ever reviewed them, Mushkin's site is belly-up. Highly doubtful anyone will be able to help you

You may never. It is not uncommon for OEM makers of any product to not put their own company name on it - that's likely part of their agreement with the "brand" company that ends up put their own name on it.

FTR, I just fired up HWiNFO64. I have Corsair RAM but no where does HWiNFO say who makes the actual modules. I know that Corsair has used Samsung, Micron and Nanya chips but it does not say on them who does. But again, it does not matter as Corsair, Crucial, Kingston and the others all sell RAM to specs. This is why we can (these days with modern, precise, production techniques ensuring near exact tolerances and adherence to published specs) we can mix brands on the same motherboard with no compatibility issues - at least not the vast majority of the time.

That's expected. RAM chips do not have something like PCI ID, so you can establish identity by querying something. It's all based on someone inspecting the chips used and adding the info to a database.

there was an app that did that, I think it was speccy. Maybe a few others do as well.

Try cpu-z and observe the spd tab.

 

[Bill_Bright]

Right. I wasn't expecting it to show the OEM maker, but did want to verify my facts before posting. That's why I checked.

RAM chips do not have something like PCI ID

The individual chips don't. But the sticks do. HWiNfO clearly and correctly identifies 2 of my RAM sticks as Corsair VCMK16GX4M2B3200C16 and the other 2 sticks as Corsair CMK16GX4M2B3200C15. Now for sure, it does not show who manufactured the individual memory ICs, but that clearly indicates to me Corsair could have, but simply decided not to include that information.

As for Speccy, I still have it and decided to check that too. I was surprised to see a new update, V1.33 dated 12 June 2024. Anyway, it does not show the IC OEM maker either.

Try cpu-z and observe the spd tab.

Surprise! That information is there. Mine clearly says Module Manuf. Corsair and DRAM Manuf. by Samsung.

Just checked each of my 4 sticks. Oddly, CPU-z shows Samsung only on the C16 sticks in Slots 1 & 3, not on my 2 C15 sticks in Slots 2 & 4. ???

Agreed.
Fwiw, I was just talking about ICs, because that's what the OP was asking about.

Understood. We are on the same page.

 

[sneekypeet]

While listed as micron, most of what I saw was called SpekTek, which are ICs made by micron that do not pass their qualifications and are sold away.

Some memory sticks may not include complete SPD information or cpu-z doesnt access the information the same way as Taiphoon burner.

Could also be because of mixed matched memory, I am doubtful of this. Could try and swap the memory around c16 to the c15 slots, or just the c15 by themselves. Doubtful worth all that for information you don't exactly need because your system is running fine.

This information is limited.

So looking at say DDR4 Samsung, this doesn't tell you what exact die samsung is using. Could be D-die. Or maybe B-Die.

There is also 3 main styles of PCB revisions some people look for specifically A0 or A1 PCB with a nice set of Samsung B-Die.

All this to get an idea of possible overclocks and faster timing sets a user may want to try. For performance increases or perhaps latency reduction. Maybe in the OP is just curious? Not sure.

I'm not that curious. Maybe next time I'm in there, if I remember, I might try it but it is not a big deal for me. They work as expected. That's what I care about.
