If your processor supports both ECC and non ECC then this should work without issue. Although be very careful about buying registered RAM. I do not believe AM3+, lga1150, lga1155 or lga1156 support REG ECC at all.
i ordered an ASUS SABERTOOTH 990FX R2.0 mobo & an AMD FX-6300 Vishera 3.5GHz (6-core) CPU
i know these both support ECC RAM, i just didn't know if there would need to be any reconfigurtion when i switch from non-ECC to ECC (unregistered), or if it was pretty much just plug-n-play.
Silent corruption. Imagine the following scenario: You copy a file to your NAS. When it hits your memory, one of the 0's turns into a 1 due to... I don't know. Solar radiation, your wife running the microwave, static electricity in the air, something. The file completes the copy to the hard drive, and you're none the wiser that it did not copy perfectly... Until you try to use the file, and get a CRC error.A quick easy question. Why a nas MUST need ECC? I built an alike nas without ECC and it runs 24/7 for months withou any issue.
Good explanation ... but you might never get any CRC error indication (from ZFS) IF that bit-glitch occurred prior to ZFS starting its protection of that data. (Ie, over the network, or upon its initial write to the ZFS host OS buffer) I believe ZFS has some copy tools to help eliminate this possibility.Silent corruption.

Yup, Murphy is a sneaky b*st*rd.It's incredibly unlikely, but possible. Non-ECC RAM works just fine 99.9% of the time. Folks who buy ECC are preparing for that 0.1%.
Correct. If ZFS gets corrupted data, then ZFS will not repair it. It will store the corrupted data. This is the reason people recommend ECC RAM, because ZFS does not protect against RAM corruption. RAM protection is not ZFS responsibility.Good explanation ... but you might never get any CRC error indication (from ZFS) IF that bit-glitch occurred prior to ZFS starting its protection of that data.

For those curious, the current Intel CPU which offer RAS protection is the E7 line. The E5s and E3s, sadly, do not. It's really amazing that we're operating at a level where alpha particles and cosmic rays are something we need to worry about.So cpus are not safe against data corruption neither. You would need a cpu with good RAS for this.
