So that...it is correct form of command?

zfs set ZFS_DEBUG_MODIFY=on

I never have problem with non ECC RAM and board.

My point is:

1 if I store only internet download video & Music, ECC is not needed, you can always download a working version of your favorite film / series /music.
2 if you want to store valuable data like personal photos , do not store only in one site, use Dropbox, and other simmilar services, so Why you need ECC?.
3 If you really need ECC, to avoid data corruption, USE ECC and Board that support it, do not use workarrounds and normal boards, use proffesional grade motherboard with ECC.

In system/advanced/sysctl.con set vfs.zfs.debug to 0x10
And issue the command sysctl vfs.zfs.debug to see if the value is accepted
If not set it manually to check it this works This will enable the in memory checksumming to reduce the chance of an unnoticed buffer corruption.

Thanks a lot erik, and sorry that my answer do not work, I strike the post to avoid confusion.
