SQUEAKY WHEEL GETS THE GREASE: gigabyte aorus elite ax working now with f30 bios, see wendells tweet. Go team!!

I hope that complete ECC memory support will someday become a standard feature everywhere.

Registered ECC should be the standard for all computing today. The fact that JEDEC member companies still view security and data integrity as premium features for only certain classes of consumers is a total ethical failure.

Why in 2024 is all memory not ECC? I mean its not that much extra cost to have un buffered ECC.

I love that all of these combinations are possible in 2024. However the reality of the ECC UDIMM market is that any savings you make, you pay for in ridiculous sticker shock and compromised halfway features like only half your DIMM slots populated, etc. I went with a used Milan CPU and a new RomeD8-2T mobo last year, and I'm still pretty tickled with it. I got 256GB of 3200 DDR4 RDIMMs for $381. I can barely get 64GB of DDR5 ECC UDIMMS for that price...

You may be the first to directly say: these are renamed ryzens. While it seems a bit obvious, it has been surprising how many either just ignore that or tip toe their way around the issue. See tech tech potato, geerling, etc... Also, the low end epyc 8004, though a bit of a pain to get a hold of, isn't a massive amount more than a ryzen/epyc 4004 setup, except it has all the pcie lanes and other server must haves you could want. Also lower power depending on the chip.

I will not be buying another PC without ECC. It's too risky with the amount of RAM these days. Memory corruption is very real and the more RAM you have the higher chance for a bit flip to happen.

So in short ECC on a Ryzen platform is still hit or miss. Disappointing

DDR5 should have enforced full end-to-end ECC and 1 DIMM per channel. JEDEC seems to think consumers don't care about the integrity of their data and stability of their machines.

Us consumers will forever be second class citizens to hyperscalers and the like…

Is a memtest86 enough to tell you if ECC work? I've tried this and it's showing as enabled and my system shows 72bits too with dmidecode

Memory on AM5 is such a pain in the ass.

I got the X570D4i second hand some years ago, while the firmware and bmc are kinda buggy, I've never had better customer support for something I don't even have the receipt for. They've walked me through testing my ECC SODIMMs (even sending them to Taiwan for me) and talking to kingston to add a note that some specific model didn't work on Zen 2. I highly recommend them! Only sad thing is that the APU models (useful for lower power consumption) need to be the PRO version, otherwise the Unregistered DIMMs don't work...
