Many people have strong opinions on why ECC RAM is not the standard in modern PCs... cosmic rays definitely can be a problem.

Despite ECC RAM being essentially a hard-to-find specialty part, it typically only costs about 20 percent more per DIMM than non-ECC does at retail. The real problem is that without motherboards and CPUs which support it, it won't do you any good.

In case anyone here is looking for non-server hardware with true ECC RAM support (not to be confused with the inferior "on-die" ECC):

Most Asus socket AM5 motherboards support ECC.
The CPUs that fit those motherboards also support it.
These Kingston ECC DIMMs are unbuffered, and fit those motherboards. They use Hynix DRAM chips (M-die, I think).
These Micron ECC DIMMs are also unbuffered, and should work as well. (Note that the part numbers may vary in retail listings.)
