I agree. The only processors that seem to support it are designed for servers (eg Xeon). Other processors say they're compatible but don't actually use the ECC part of the memory.
I built a ML workstation for my work team and was disappointed that my options were: expensive, low clock speed server CPU + ECC, or inexpensive, very fast, desktop CPU without ECC. Even if I were willing to pay more money, it was really hard to get the same performance if I needed ECC.
- Leo_Verto 6y agoThat's just Intel though. All AMD Ryzen CPUs without integrated graphics do support ECC although YMMV depending on the motherboard you use.

- CodesInChaos 6y agoSupposedly AMD Ryzen and Threadripper support unbuffered ECC with the right mainboard (Asrock was mentioned several times).
- account42 6y agoI can confirm that Threadripper does check for errors with ECC ram. (MSI motherboard in my case but it should work with all of them)
- segfaultbuserr 6y agoIt's intentional. Intel has a tradition to cripple features on consumer and enthusiast-grade CPUs in order to sell more Xeon CPUs. The way Intel crippled virtualization/IOMMU in the past was also particularly annoying - on mainstream CPUs it was allowed, but on overclockable enthusiast CPUs, it was disabled. On the other hand, AMD doesn't do that.
