This is really nice for home servers. There has been a huge gap for years where the choice was a 16-64 core high watt monstrosity or use a 4 year old server CPU before every server went to high core counts.
Could be but finding a motherboard that has verified ECC is tricky. Most say works but not tested/supported so you're on your own to figure out if ECC fully works.
The server/workstation focused ASRock Rack AM5 mainboards list plenty of ECC modules in their QVL. The "gaming-focused" ASUS B650E-E I'm using even has two ECC modules listed in its QVL.
So you could've already gotten verified ECC support, the fact that the same CPUs now exist with a different (EPYC) branding doesn't change that. Finding these mainboards isn't particularly tricky either.
"ASRock" and "ASRock Rack" are two different series of motherboards.
Here's the QVL of one of their AM5 mainboards: https://www.asrockrack.com/general/productdetail.asp?Model=B650D4U-2L2T/BCM#Memory - it doesn't limit these modules to specific CPUs. All CPUs with ECC compatibility also support these modules on this mainboard. Some of these Rack boards are over a year old, and they always had some ECC modules on their QVL. This - again - isn't EPYC 4004 specific, they couldn't have validated it with EPYC 4004 CPUs a year ago. In fact, their CPU support list doesn't even list EPYC 4004 CPUs as of today, as they haven't released a BIOS update adding (official) compatibility in for these CPUs (it will probably be released shortly though).
ASRock Rack AM4 mainboards also officially support ECC memory. So if you wanted verified ECC support on a comparatively cheap AMD platform you could've always gone for one of these boards with a regular Ryzen CPU (not an APU). The boards are a bit on the expensive side but if you want official support (for whatever reason you'd need that in a homelab environment) you can get it.
I'm curious, what do you or anorher "classic"(?) home user do that needs more than like an old intel 6500 with say 32GB RAM and some 1 TB SSD (hoarding etc goes to the NAS right?) of storage?
I know dockers consume, or so I have heard, but even a webserver, streaming etc is that really eating up the (pcie)bandwith?
I'm just a low end tinkerer who likes to buy over specced stuff so I wonder what's you all doing with yours I guess!
Plex, Blue Iris, Minecraft mod servers for the kids. I'll often use the server CPU for video filtering/encoding home videos off of VHS tapes because the nnedi3 filter takes a lot of CPU.
Years ago I lost data on a nas because the ram wasn't ECC. So I won't buy/build any PC without ECC unless it's only going to be used for web browsing/gaming.
We're on the same boat. I keep being told that all I get is "overkill", but I like to think of it as "future-proffing", even though I'll probably upgrade something in my box within 3 months 🤣. Self-delusion my wife calls it. Some people don't believe in God, I don't believe in overkill.
For what use case though? Intel has nice 10-30W cpus. The trick to power consumption is to look at modern CPUs instead of digging out an old 2500k just because you still have one and aren't using it.
What id actually love to see though is ARM in the compact desktop space. If nothing else, just to see how well it can do against x86-64.
