I also have the Skullcanyon, as a laptop replacement machine. None of my previous personal computers have had ECC RAM, but none have had more than 16GB either. What is your use case that benefits from error-correction, if you please?
http://serverfault.com/questions/674214/what-is-the-rowhamme... adds "ECC effectively turns the Row Hammer exploit into a DOS attack. 1bit errors will be corrected by ECC, and as soon as a non-correctable 2bit error is detected the system will halt (assuming SECDED ECC)."
That said, if a bit flips in the wrong place in RAM, even a checksumming file system will not protect you. The file system will happily write out the corrupted data if the checksum is calculated after the bit flip occurs.
