In reality ECC is like twice the price, the CPU support is close non-existent too (Intel just has been disabling in the memory controller for ages... unless it's an i3 laptop - then it's available again) Just try and buy a reasonable non-server class machine that has ECC.

Not sure where you are. But I just compared Crucial DDR5 32GB DDR5-4800 (PC5-38400) and the non-ECC (on CDW.com) is $186.99 for part (CT32G48C40U5) and $229.99 for part (MTC20C2085S1EC48BA1R) a 22% premium. All Alder Lake chips (the ones shipping in volume today) support ECC, check ark.intel.com to be sure. For example the popular i7 model (https://ark.intel.com/content/www/us/en/ark/products/134591/intel-core-i712700-processor-25m-cache-up-to-4-90-ghz.html https://ark.intel.com/content/www/us/en/ark/products/134591/...) As do all Ryzen desktop chips (5000 and 7000) do as well. Granted popular consumer products don't have ECC, but it's pretty straight forward to built it yourself. Just make sure the motherboard you buy (Intel or AMD) supports ECC.

AFAIR, every AMD64 CPU has ECC support. But not every motherboard had necessary layout and BIOS support. That's why I'm 20 years with AMD and choosing components carefully. Every system with > 4GB RAM should have ECC. Proven decades ago.

  They (ryzen) sort of do - unofficially. Which also means that the motherboards won't list the memory compatibility, either... or tune the bios.

    Varies by board, ASRock (at least some boards) supports it, documents it, it's in the BIOS. It's not unofficial, AMD lists it in their specifications.

  Not all. Was purposefully locked out of the Ryzen APUs, and parts without the iGPU enabled based on an APU die. And that, until Ryzen 7000.

    Yeah, I was talking about CPUs precisely. On my APU, unfortunately, there's no ECC support even if I shove a module in. PS: and being a pre-ryzen AMD user, I don't know much about new CPUs too :))

It's the other way around now. The 12th gen "Core" desktop parts all support ECC in the i5/i7/i9 SKUs.

  Does it still need to be allowed by specific chipsets, though ?

    Yes, you need the W/R680 chipset on this generation.
