I have a question about ECC function on ASRock AB350M. According to specs, it supports ECC memory:
If I install ECC memory, will it also operate in ECC mode? Or will ECC memory work only in non-ECC mode in this board? |
Supports DDR4 2667/2400/2133 ECC & non-ECC, un-buffered memoryReplies:

I don't understand the purpose behind the question. Of course a socket AM4 CPU or APU. Currently options are Bristol Ridge and Ryzen. Later this year Ryzen Pro or Raven Ridge. If the answer to my question depends on the CPU, then of course I would be also interested in learning which AM4 CPUs are ECC capable. |

It does. |

Remember, the memory controller is now within the CPU itself. No support from the IMC concerning its ability to function using ecc means no. And truthfully, I can't find a straight up answer to what AM4 chips do other than maybe the PRO line due out at a later date. Reddit has an upcoming AMA with AMD concerning Ryzen and I plan to be there, questions in front of me. |

Look, I'm aware that the IMC needs to support ECC. Also the socket AM4 needs to have the necessary pins (FM1/FM2/+ did not). I agree that the question which Ryzen models support ECC is one that needs to be directed at AMD. https://community.amd.com/thread/210870" rel="nofollow - I asked, they refused to answer. But the question whether ASRock AB350M supports ECC function (given an ECC capable CPU) is one that needs to be answered by ASRock and that is why I am asking here. |

You will likely have to wait a while for a reply, being that functionality is determined by the CPU ASRock is likely still bound by AMD's NDA regarding support. Only a few days before Ryzen hits store shelves though so it won't be long now. -------------

Ok, so ASRock support staff seems to be not well informed and is spreading contradictory information themselves. To one Reddit user, they wrote that ECC memory works, but only in non-ECC mode:
To one Hardwareluxx (German tech website) forum user they wrote that ECC is fully supported:

No one from ASRock posted in that forum, someone claimed ASRock had informed them that ECC would work. In all likelihood the information was misunderstood and/or misquoted. The products have not even hit the shelves yet and much of this information is still under NDA from AMD, ECC support will be determined by the memory controller in the CPU. I am sure things will be more clear and easily available once the products are actually available for purchase. Another point worth noting is that while I am a moderator here I do not work for or represent ASRock on these forums yet my words are frequently misused as proof that ASRock supports or does not support something. Just as many people assume that these forums and it's moderators are somehow part of Tech Support. While Tech Support posts here on occasion we are not them. ASRock_Official will be under the name of any ASRock employee officially posting in the forums here, and Admin Group obviously. My point is, anyone can claim to have spoken to ASRock or even claim to BE ASRock employed but unless it comes from a sanctioned source it needs to be taken with a grain of salt. Contacting ASRock TSD directly using the support form or by email/phone or an official post here are the only ways to get this information from the horses mouth, so to speak. The fact that ASRock_TSD has not replied this thread (and I know they have been online and seen it) tells me that the information is not officially available yet. Again, speculation but I get the feeling I am right. -------------

With FM2+ boards, #2 already prevented ECC from happening (this time no workaround). But same CPU/APU in FP4 package supported ECC fine. Do note that AM4 products based on Bristol Ridge are already launched and officially listed on http://products.amd.com/en-us/search/APU/AMD-A-Series-Processors/AMD-A12-Series-APU-for-Desktops/7th-Gen-A12-9800-APU/201" rel="nofollow - AMD products website , so I don't see why #2-#4 should be covered by NDA. And this is all I am asking from ASRock. |

Oh I do get it, I was just pointing out that if I can't get an official answer from ASRock on the matter then I doubt the sources you quoted earlier in the thread were accurate or in fact from ASRock  I am still waiting on an answer to this question myself, when I get one I will post it here for all interested. Bristol Ridge is not Ryzen based so the information may not be relevant to Ryzen. I do find it difficult to believe Ryzen will not support ECC given it's target market but AMD may not have felt it was relevant... I guess with Ryzen out now we should see more information become available very soon. Day one reviews are up and Ryzen is performing right on par with what I expected to see. Yes there are some teething issues and kinks to work out and no doubt some software updates to accommodate new features but all in all, it looks very promising, especially for home workstation use. -------------

If AMD themselves isn't giving anyone a straight answer yet what makes you think ASRock c/w/ould? The memory manufacturers knew that well before today and I with my personal contacts at a couple couldn't get more that a giggle, <cough>Under NDA<cough> and a You'll have to wait and see. We Moderators here, not being your avg User, have many friends/industry insiders to call upon yet a tight lipped ship is a tight lipped ship. |

Today in the Reddit AMA, the question whether Ryzen supports ECC was answered by by AMD in the positive: https://www.reddit.com/r/Amd/comments/5x4hxu/comment/def6vs2" rel="nofollow - https://www.reddit.com/r/Amd/comments/5x4hxu/comment/def6vs2 Also they were made aware of the confusing statements by mobo makers and promised to get consistent messaging out. So now I'll just wait for someone from ASRock to officially state whether ECC memory installed on the AB350M will operate in ECC mode or in non-ECC mode. Thanks wardog and Xaltar for the helpful replies. |

Now that Ryzen has officially launched, ASRock, us, nor anyone else is now under NDA, please see the Memory section of the below AB350M Specs page: (sorry chithanh, but I was under NDA)http://www.asrock.com/mb/AMD/AB350M/index.asp#Specification
