All desktop Ryzen CPUs without integrated GPU, i.e. with the exception of APUs, support ECC.
You must check the specifications of the motherboard to see if ECC memory is supported.
As a rule, all ASRock MBs support ECC and also some ASUS MBs support ECC, e.g. all ASUS workstation motherboards.
I have no experience with Windows and Ryzen, but I assume that ECC should work also there.
With Linux, you must use a kernel with all the relevant EDAC options enabled, including CONFIG_EDAC_AMD64.
For the new Zen 3 CPUs, i.e. Ryzen 5xxx, you must use a kernel 5.10 or later, for ECC support.
On Linux, there are various programs, e.g. edac-utils, to monitor the ECC errors.
To be more certain that the ECC error reporting really works, the easiest way is to change the BIOS settings to overclock the memory, until memory errors appear.
