Is an ECC ram enabled GPU necessary for a server, or will a normal gpu work fine in a server?

Is it a requirement for a server to use ECC ram on a GPU while the normal CPU ram is ECC? Im thinking that instead of using a Quadro k6000 or AMD Firepro, we could use a GTX 980 or AMD r9 290...if possible... Also, if it is not necessarily required…

Where are the ECC memory error counters stored?

Where are the ECC memory error counters stored: on the DIMM itself, the motherboard, or the host's disk? I'm using memtest86+, but it seems that it doesn't recognize ECC on my system, so if correctable errors occur, memtest86+ just won't see them.…

Alternative file system/volume manager for ZFS w/ non-ECC RAM?

It's not recommended to use ZFS for a computer without ECC RAM. So, what's a good alternative then? Or is the risk the same, so it doesn't matter what manager I use, it'll be the same problem if a bit in RAM flips anyway? I'm trying to determine if…
