Of all youtubers, unexpectedly Hardware Unboxed tested ECC support on some X870E boards…
The result is somewhat surprising. Gigabyte and Asrock have ECC working, Asus posts but without working ECC, MSI does not post at all…
They tested memory speeds too, with all boards except Asrock reaching 8000+ speeds, with Asrock stuck at 7400MT. Interesting, since Wendell had 8000MT working… Bios updates might improve compatibility I guess?
Don’t wanna sound like a dick but do they know that sometimes ECC has to be manually enabled in the UEFI? “Auto” doesn’t automatically mean enabled.
The tested ASUS motherboard supports ECC according to its specs website so maybe its a bug if the UEFI setting is without any effect.
Wouldn’t be the first time, but ASRock is one of the worst offenders here and no matter which manufacturer you choose if you want to use ECC be sure to always verify it to be working with software like PassMark Memtest that can test for actual memory corrections not only if the platform reports to the operating system that ECC is present.
That said, MSi is the worst manufacturer not implementing ECC memory on the consumer AMD platforms in general, was the only one with AM4.
PS: I myself am an ECC fetishist so no complaints here making ECC more popular in general consumers’ minds.
Fair enough. They are mostly a gaming channel (at least those are the benchmarks they do almost exclusively). So given Asus had good ECC support on X670/B650 it’s definitely possible they forgot a BIOS setting. Or a UEFI bug.
I thought it was noteworthy though as it’s the first data I saw on ECC with X870.
Seems like it. At least they are clear about it, their specs show non-ECC memory support only.
Agreed. I sadly caved waiting for ECC 48GB modules, and got non-ECC ones since I didn’t want to wait any longer.
I have ASUS ProArt B550, X570 and the X670E motherboards in use (with ECC working) and noticed that AMD or ASUS rearranged ECC settings on the AM5 model, I’d suspect it looks the same on the ASUS X870E motherboards, maybe that confused them.
My first post here, so hello all 
I’ve just had a look at the specs, and it seems that in case of Gigabyte, “Master” model (~550eur in retail) is the ONLY ONE that supports ECC, while in case of ASRock every model, even the cheapest ~220eur “Pro RS”, has ECC support. If this is correct, then ASRock has just put every other mobo manufacturer to BIG shame with its cheapest model…
So is any owner of ASRock Pro RS able to confirm that it indeed supports ECC? Thanks!
The AsRock Rack department is certainly beneficial to general BIOS changes and proper ECC support.
I was surprised when I updated my BIOS on the X670E Steel Legend. I sadly never had the RAM to test with as there were no DDR5 ECC UDIMMs for sale when I bought it. But BIOS 3 months after (Zen5) launch got all the BIOS entries I see on my server BIOS as well.
Sounds familiar. But it’s on my daily driver and ECC isn’t that important…certainly not 500€ important for 2x48GB modules. Server gets the expensive stuff, Desktop is dirt cheap stuff that works (cheap 64GB 5200MT Kingston).
