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.)
