I've built 9 AsRock AM4 based machines with ECC UDIMMs.
Most of them don't get hammered much, and I never overclock anything, so error events are likely exceptionally rare. Over some 5 years, I saw exactly ONE corrected ECC error, from the build using Ryzen 3 PRO 2200GE, running FreeBSD.

So on that machine (Fatal1ty B450-ITX/ac), I'm certain it works.

I have other machines with 2700, 2700X, 3300X, 3600, 5600, 5800X3D, and all indicators say the ECC functionality is working. I also have one with PRO 4650G.

My understanding is that any non-PRO APU-based parts (4600G, 4500, 5500, etc.) do NOT support ECC. If the die is APU-based, then it must be PRO. For non-APU parts, ECC works on all parts (2700, 3700X, 5700X, etc.).

On a side note, it's amazing how cheap DDR4 ECC UDIMMs are these days, and they're easy to buy also, directly from Crucial.com

Did you get the ECC memory working?]]> Sun, 04 Jun 2023 12:33:43 +0000 https://forum.asrock.com/forum_posts.asp?TID=14084&PID=105065&title=asrock-b540m-pro4-and-ecc-ram#105065 https://forum.asrock.com/forum_posts.asp?TID=14084&PID=74591&title=asrock-b540m-pro4-and-ecc-ram#74591 Author: sjau

And by memcheck I mean memtest :)]]> Thu, 23 Apr 2020 19:50:43 +0000 https://forum.asrock.com/forum_posts.asp?TID=14084&PID=74591&title=asrock-b540m-pro4-and-ecc-ram#74591 https://forum.asrock.com/forum_posts.asp?TID=14084&PID=74590&title=asrock-b540m-pro4-and-ecc-ram#74590 Author: sjau

Thanks for the reply.

I did now test the B450M with a Ryzen 5 2600X and 2x Kingston ValueRAM Server Premier (1x, 16GB, DDR4-2666, DIMM 288). Also I needed a gpu - the cheapest I could find was a Gainward GeForce GT 710 (1GB).

Memcheck86+ just spit out gazillions of errors:



But someone suggested that memcheck86+ might not be up to the task since the hardware is so new.

So I tried out the free version of memcheck86, which spit following out:






So, it didn't find any error.

If you check the memcheck86+ screenshot you'll notice it doesn't even recognize the hardware correctly (chipset: unkown ; memory type: unknown) while memcheck86 did properly identify ram etc.

So, this combination works with ECC and it spit out no error.

Hi there

I changed my homeserver a while to zfs for file storage (10 disks, 60TB) and one weak spot is the lack of ECC ram. So right now I'm looking for a new mainboard, ram and cpu. As it's mainly a server for backups, media storage (plex) I don't really need a lot of powerful hardware.

As of now I just need to be able to attach a Dell H200 in IT mode and have at least 4 onboard sata connectors. Also zfs likes ram and occassionally I run 1-2 vms on it. So I go with 32GB of ram currently while still maintaing the option to upgrade to 64GB later.

Anyway, on my search I came across the B540M Pro4. According to the manual it should support ECC Ram (in ECC mode - I've seen some mainboards that run ECC ram also but not in ecc mode...).

?? Dual Channel DDR4 Memory Technology
?? 4 x DDR4 DIMM Slots
?? AMD Ryzen series CPUs (Pinnacle Ridge) support DDR4

?? AMD Ryzen series CPUs (Summit Ridge) support DDR4

?? AMD Ryzen series CPUs (Raven Ridge) support DDR4

* For Ryzen Series CPUs (Raven Ridge), ECC is only supported
with PRO CPUs.
* Please refer to Memory Support List on ASRock?™s website for
more information. (http://www.asrock.com/)
* Please refer to page 22 for DDR4 UDIMM maximum
frequency support.
?? Max. capacity of system memory: 64GB
?? 15μ Gold Contact in DIMM Slots


I'm a bit confused what Ryzen series can run what kind of ram.

As for the CPU I will need Pinnacle or Summit Ridge to run ECC Ram. However will those ECC ram run in ECC mode or can you just also use ECC ram instead of non-ECC ram?]]> Sat, 11 Apr 2020 20:35:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=14084&PID=74255&title=asrock-b540m-pro4-and-ecc-ram#74255
