ECC ram is meant for servers.i was thinking of getting some ECC RAM but the cost was too high and i didn't have a need for that.
I could've gone with some Bdie sticks but that would've cost more than 50k for 64GB, so went with Corsair LPX, which IMO, is the best stick around if not getting Bdie or ECC.
There are only 3 major chip manufacturers used by ram brands--samsung,hynix & micron(crucial owned). I recently read some comments on reddit that adata D30 3600MHz ram was using samsung b-die. In any case you won't miss on anything by not getting corsair lpx because it will most likley be using hynix/micron chips same as other brands if it is not samsung.
