I already avoid intel chips because they paywall ECC.

My NAS runs on one of the cheapest (and most power efficient) CPUs AMD ever made, but it's fully stacked with ECC RAM for my ZFS ARC.

That sounds really interesting. Any details on which processor/mainboard you used?

Asus and Asrock mainboards, and some Gigabyte ones support ECC on AM4 boards. AFAIK all CPUs are good except the non-Pro APUs. We have a Ryzen 1600X, 1800X, several 3900X, and a 5800X all working with ECC.

Thanks for this. I've just seen the Gigabyte B550I Aorus Pro which does ECC and is miniITX too. Would make a nice low-dissipation system with a Ryzen 5650GE Pro APU.

But, my, how prices for this kind of stuff have shot up over the last few years...

Complementing the sdalley question.

Which ECC Ram kit are you using?

We use whatever is available at a good price. In our 5800X box we use 4 Kingston KSM32ED8/32ME.
