Some devices with 13th gen Intel processors support in-band ECC. This basically hides a fraction of RAM from the OS and uses it for ECC.

Example devices are: LattePanda Sigma [0] and AsRock Industrial NUCS BOX-1360P [1].

Unfortunately they are quite expensive and enabling in-band ECC lowers performance significantly. So my next server rig will likely have an AMD PRO CPU instead.

I find it annoying that (a) this seems to be a hardware feature that is almost universally permanently disabled in firmware and (b) it's almost impossible to find out whether it is supported by any given product (neither of the two products you link provide any mention on the spec sheet).
