By confirm I meant that people actually had the setup and ran memtest86 on it to verify ECC was doing its job. I get what you're saying and I don't disagree, but I spent hours the other night going through forums all over the internet looking for folks who had this working and could confirm it. I will admit that I don't have a lot of experience using memtest myself and I don't know what it does to verify the functionality of ECC or if simply just looks at the bios to see if its enabled. Because as you said, it could "work" but perhaps not with any of the actual functionality.
only AMD platforms that support ECC are Epyc and Threadripper. Ryzen CPUs are out.
The link you posted states that Ryzen is supported. The way it reads to me is, when APU is present then it must be PRO. But a chip without an APU should be fine.
I reached out to Asus for clarification and after they put me on hold for awhile to look into it they said they didn't have that information available and to contact AMD. Reaching out to AMD has been a struggle.
I just keep adding to my reply and never posting it...
When to microcenter today, they price matched harddrives with newegg (which were on sale :p ) and the ryzen was only $150. The ram I had to order and should be in monday/tuesday. I'm going to be the guinea pig here gamble ECC on a ryzen. For the boot drive, I had a 250gb 960 evo laying around and I'll cannibalize a seasonic 750 modular psu from an old computer. (i have a 430 seasonic but not modular)
Until I figure out what I want to do about a GPU (for transcoding), I have several options on-hand to get me by for now: Quadro NVS290, NVS440, geforce 7300GT, 8600GTS, PC5900, 660gtx.
Once I get the ram, if I'm having any issues I do have 15 days to return the cpu/motherboard. In theory, it should all work. Emphasis on theory!
