Ryzen Memory IC Collection Thread

241466 181
To participate in the list all you have to do is download the portable program (no install necessary) Thaiphoon Burner and post a screenshot of your RAM here.

A list of missing RAM kits is at the end of the post.

In general (on Ryzen) you can expect up to 3466 MHz (without BCLK-OC) with Samsung B-Die (on AGESA 1.0.0.6+ Bios Versions), up to 2933 MHz (without BCLK-OC) with Samsung D/E/S-Die (AGESA 1.0.0.5+). Hynix A/M-Die are mostly working @ 3200 MHz with AGESA 1.0.0.5+. Do note that Dual Rank RAM is faster than Single Rank. E.g. 2933 MHz Dual Rank is faster than 3200 MHz Single Rank. Single/Dual Rank is not to be confused with Single/Dual Channel (Dual Channel is always better).

You can expect color subvariants (see legend below) of G.Skill RAM to have the same IC as the regular version. This is why color/RGB versions are listed as the standard version, e.g. GVR -> GVK / GTZKW -> GTZ, unless no "standard" version exists (e.g. F4-3000C15D-16GVR & F4-3000C16D-16GTZR).

3000 MHz CL15 & 3200 MHz CL16 are special cases because multiple subtiming versions exist (e.g. CL16-16-16-36 & CL16-18-18-38).
Entries marked with * indicate that you may get Samsung or Hynix IC, both variants exist with the same model number.

Hey guys so i just made an account because of this.

I recently downloaded Taiphoon burner and i noticed with 1 sticks that i got an CRC error.
It says that it got an error at the SPD Protocol section, see picture below.

Click here for pic: https://imgur.com/a/ou731Qj

What can i do to solve this? Sometimes i get a random black screen and i think this is because of this.... not sure tho..
related perhaps? https://www.hwinfo.com/forum/Thread-SPD-Checksum-Errors-w-HWiNFO64-Running

Have you stress tested the ram to check for errors?
I've had a few problems from overclocking my ram and writing errors to my drive because I didn't do the stress testing

Why is HWINFO showing 1.82 for VTT? On MSI b450 Tomahawk, 2133hmz? Funny thing is it shows the same at 2933mhz. is that anywhere near normal? Im reading that vtt should be about 1/2 of Dimm volts, and dim is like 1.26 max.

got an answer over at HWInfo forums. From Martin, its a generic reading and is not actually IMC/vtt. Hes removing it from next version.

For those who care about capacity: 128 GB on 1st gen Zen. (4 x 32 GB)

Not officially supported, but it seems to work anyway. It did take a couple BIOS updates though.

CMK64GX4M2D3000C16 - Micron B-Die

This ram is supposed to go in my 3950X build planned for this month. But since AMD pushed that back, I figured I'd try them in an older box. (I need to make sure they're not DOA.)

Anyone Able to Identify What Samsung IC This Is?

Been looking to upgrade to 32GB on the cheap while having a chance at decent performance via tuning and noticed this 32GB (2x16GB) DDR4-3000 CL16 kit of GeIL Evo Potenza model #GAPB432GB3000C16ADC being advertised as specifically designed for AMD Ryzen going on sale for $93, and I ended up getting it at Newegg's eBay store for a paltry $74 after 10% off from a coupon and 10% Bucks.

According to Newegg, this kit was first available on 10/07/19 so there's no reviews or info on the web about it and based on previous data points I surmised it would be Micron B-Die but it ended up being some type of Samsung IC after installing and checking BIOS and with the latest version of Thaiphoon Burner. XMP worked just fine. Unfortunately, Thaiphoon doesn't have a full part number for this IC, with a read on either slot giving part number K4AAG085W?-BCPB which I couldn't find any info for whatsoever. My assumption would be Samsung D-Die, but the info I can find for it online points to a part number with K4A4G085WD, and of course if it were E or S-die the part number would end with those letters. Instead, I just get a question mark. The manufacturing date for the DRAM is very recent, November 4-8/week 45 of 2019 which is less than 1 month ago. Anyone got any info on these? Thanks so much in advance. :thumb:

What Samsung Die is this?

G.Skill Trident Z F4-3600C15D-16GTZ

Works well at 3266 14-14-14-30 on my Ryzen 2700 / Asus Prime X370 Pro.

Thaiphoon reports Samsung D-die, but works well with the "Safe" B-die timings from "DRAM calculator for Ryzen".
G.Skill support says Thaiphoon is correct as dies can change between batches, but the calculator doesn't have any support for 3600 speed D-die, or single rank D-Die that big.

Does anybody know what die "K4A8G085WD-BCPB" is?

Hello guys and happy holidays.After having a lot of problems with a memory kit i bought(g.skill 4000MHz CL18-22-22-42), it cant even run on 3200 cl 16 on ryzen 2700x i found a new one at a good price but i have no ideea if it's b.die or not.I havent found any sure answers, one post on reddit that said its not b.die and not much info.
I wont recive the memory very soon, maybe at least 1 or 2 weeks from now.
This is the kit, i emailed g.skill and asked them if this is b.die but i'm sure it will take some time for them to answer.

According to this, it is B Die:

Could you please add some more info to the OP on why we would want b-die, or some other "die"? "IC" has also not been defined.



From the "b-die finder" website it seems that b-die is significantly more expensive. Often twice as much or more. So it seems there needs to be a very good reason to pay more for b-die.

G.Skill Trident Z F4-3600C15D-16GTZ

I JUST got a new Trident Z Neo kit: 3800C14-16GTZN. My kit also reports the same part number; K4A8G085WD. The 3800C14 kit works great at 14-15-15-34, but HwInfo reports it as Samsung D-Die; which I think is a mistake.


I'm running R9 3900x, F4-3800C14-16GTZN 16Gb kit dropped in and enabled xmp, MSI 1080ti, AsRock x570 Taichi




I suspect that it is mislabeled in Thaiphoon or something, because the numbers I am getting is insane.



I also read that we are mistaken in thinking that Samsung stopped producing ALL b-die instead of just one product line of it; I can't remember exactly where, but the source pointed out that the public twisted the wording around to make it seem like they stopped all production.


I don't think anything except b-die could run these INSANE numbers. I've got my Infinity Fabric/UCLK/MCLK 1:1 OCed to 1900; but it also works well on FCLK 1933, if a little unstable.










Edit:




Could you please add some more info to the OP on why we would want b-die, or some other "die"? "IC" has also not been defined.

From the "b-die finder" website it seems that b-die is significantly more expensive. Often twice as much or more. So it seems there needs to be a very good reason to pay more for b-die.

Samsung B-Die is often touted as better than other ram dies (eg Hynix CJR, . The architecture of b-die makes it especially prone to having both high clock speeds AND low latency at the same time. Therefore; it is highly overclockable, and able to tighten timings very very well. No other ram right now can do both of those things as well as b-die.





There is also information going around that states that Samsung no longer makes b-die. This, of course affects people's assumptions about its scarcity, and therefore people will pay more for it because they think that there is only a finite amount of b-die left to purchase.



I have seen Samsung release information about b-die; and it seems that we might have been wrong, and Samsung probably still makes b-die, but they EOL (End of Life-d) a few of their b-die products, but not all of them.

Hi, so I just RMA's my Samsung B-Die F4-3200C16-16GVKA from January 2017, which was a VERY bad overclocker and received an identical kit which seems to have been manufactured April 2020.

Couldn't even do any frequency higher than it was rated for. As it's not listed like the GVK and GVKB dies I thought I'd post the Thaiphoon Burner readout here for you to add.

The only thing that changed in 3 years seems to be the manufacturer of the thermal sensor from ABLIC to OnSemi. I haven't tried overclocking the new kit yet.

Information about the manufacturing date has been taken directly from the label itself.
