I've been actually researching this a lot recently as I'm in the process of buying parts for a desktop build and want ECC support.
> Unfortunately, when the AMD Ryzen 7000 “Raphael” CPUs were launched along with the brand new Socket AM5, all mention of ECC support was gone.
1. This was effectively a big point of concern for me. Previous ASRock Taichi motherboards officially advertised full ECC support, but not the latest X670E for AM5 model. Older version of the X670E Taichi page mentioned ECC support ("Supports DDR5 ECC/non-ECC, un-buffered memory up to 6600+(OC)") [0], and this Level1Tech review [1] had a segment on ECC support (they fully tested it). The segment was around the 10min mark, but it looks like the video was swapped to remove it during the last 30 days (the original video was 17min41sec long, the current one is only 16min32sec). So I assumed that ECC was supported, but it's a bit concerning that there's no official mention. The article reassures me.
2. Finding ECC memory for desktop computers is hard. For the X670E Taichi, you need DDR5 unregistered DIMM. The best solution I have to find ECC memory is to check QVL lists for similar server motherboards, for example this ASRock Rack [2] or this Gigabyte Motherboard [3]. I decided to go with two 32GiB Kingston sticks [4] for my own build.
