See here for post that proves ECC works on Windows for Ryzen: https://www.overclock.net/forum/11-...42-ryzen-ecc-motherboards-3.html#post27646570

So we all know getting ram speeds to take well on many Ryzen boards is already an issue but an even bigger issue for many of us is lack of ECC support from the current motherboard offerings.

Please post any news on upcoming or current support for ECC on AM4 motherboards.

I currently know that ASRock lists support for ECC un-buffered memory on all of its X370 boards. I have not yet found anyone that has this and says it is working in Windows 10 yet though, but it is reported to be supported in Linux >= 4.10. Also currently it appears that it just accepts ECC ram not that said ram actually runs in ECC mode.

Please note I have yet to see any confirmation of ECC running in windows, if you know of one please post.

List of Current ECC Motherboard Support: (I will try to update this over time)

ASRock -All x370 support [Not confirmed to actually run in ECC mode] ECC unbuffered [Unconfirmed Windows support, Claimed support in Linux >= 4.10],
X370 Taichi -Linux 4.10 ECC support listed on QVL
X370 Killer SLI/ac
X370 Killer SLI
Fatal1ty X370 Professional Gaming lists 3 ECC chips in QVL
Fatal1ty X370 Gaming K4

ASUS -Support for ECC unbuffered
PRIME B350M-A/CSM
PRIME B350-PLUS
PRIME X370-PRO -3rd party claim -3rd party claim 2 Transcend ECC chips listed on Official QVL
(Yes the ROG CROSSHAIR VI HERO does NOT support ECC)

I wanted to update this thread that today I observed that Asus has 2 chips listed in the QVL for the x-370-pro
Transcend TS1GLH72V1H (ECC) 8G DS SEC552 K4A4G085WEBCPB
Transcend TS1GLH72V1H (ECC) 8G DS SEC552 K4A4G085WEBCPB

From what I can see it is the same chip but listed twice?

Here is the list from the Taichi which also now has ECC chips listed on its QVL as well:
2400 8GB Crucial CT8G4WFD824A.18FB1(ECC)
2133 8GB Samsung M391A1G43EB1-CPBQ(ECC)

Asus ticket support claimed ECC support on one specific Transcend memory kit only, and with bios 0515 and above.

Its surreal to me because the QVL only lists the memories they managed to get their hands on. And in 20 years of doing this I never used a QVL listed memory on any board I ever owned. JEDEC standards are clearly not being respected either by kingstone or asus. This being a server RAM kit, I suspect Asus is the culprit.

What I find interesting about the QVL for Asrock is that they have 3 chips listed for the Fatal1ty but only 2 listed for the Taichi... I guess they just got that 3rd stick and have not tested it in everything yet.

When new generations of chipsets first launch you really do need to stick to the QVL if you do not want to be left out in the cold. I remember this was the case back when X58 came out.

I'm ordering some Samsung ECC DIMMS for my Ryzen 5 1600/PRIME B350M-A setup this week. Ill be sure to post back with the results.

It's not on the QVL but I cannot find that Transcend stick in stock anywhere in AUS!

I'm wondering how everyone has faired with the ECC Ryzen builds.

I'm looking at buying a Ryzen 5 1600 with an ASRock AB350M Pro4 for a server build. I'm finding it difficult to find some ECC RAM for it, and more difficult again to determine if it will work beforehand.

Would be great to hear about your experiences, I would love to have some working ECC RAM in this system!

Made an account as this is relevant to my interests. I have been using 2x Samsung M391A1K43BB1-CRC on Asus X370 PRO, BIOS version 0810. No problems whatsoever (these are single-rank DIMMs using the recommended Samsung B-die chips). I haven't tried to verify that ECC actually works, but dmidecode claims multi-bit correction is in use, if that's of any help.

ADATA AD4E2133W8G15-BHYA
Crucial CT8G4WFD824A.18FB1
Samsung M391A1G43EB1-CPBQ

These are the sticks on the QVL for that board, I'd try and stick to one of those.

are folks building workstations and servers with ryzen? i've noticed even back in the ddr1 days you can still get ddr ecc to work, is this a part of ddr4 spec for intel and amd or is it just another AMD coincidence that these boards support ecc?

Yes, most CPUs support ECC memory unless the feature is deliberately disabled to differentiate the lineup. Intel does this a lot, you might get ECC support on Pentiums and some i3s on a server chipset (as of Haswell), but after that they want you to buy Xeons. AMD tends not to cut ECC (and virtualization) support from their consumer CPUs, so they've been great for budget server/workstation builds.

Asus and AsRock have the best track record for supporting ECC memory on their consumer motherboards, in my experience. At least on ther higher end models. My old M4A79T Deluxe even has a separate BIOS page for ECC settings. In practice, it is very hard to confirm a particular board has ECC support, as the specifications might state "ECC & non-ECC memory", but in reality the board will run the sticks in non-ECC mode.

Apparently, the ASRock AB350M Pro4 supports ECC memory now. They updated the website not long ago... Going to try some Kingston ValueRAM 8GB (1 x 8GB) DDR4 2400 RAM (Server Memory) ECC Micron A DIMM (288-Pin) KVR24E17S8/8MA.

Going to cost me $150 a stick here in Australia. Let's see how it goes, will report back.

AMD does not cut it from consumer CPUs to the point that you can actually run 8+GB of DDR1 on some socket 939 boards with the right revision of CPUs as some are cut down opterons. SEAFs proved that in the 939 club.
