A lot of my RAID (most) when to software RAID, or went away completely for other solutions. Out of 14 servers here, they have all evolved. ECC Registered Memory.and I was chasing the newest and most reliable hardware, which is a moving target. I 'was' a hardcore old-school server admin, in that about 9 years ago, in regard to servers up to that point: Raid, Cards, SCSI > SATA. It depends what you are doing and what your goals and the limits of your scope. It boils down to speed versus reliability. Lastly, could you give me some setup examples where ECC RAM is needed? so that i can get a better understanding. I do have a disaster management plan (run automated databse backup, twice a day, to 2-3 online storage as redundant backup.) Is ECC RAM mobo crucial for my setup? how severe & frequent is the corruption if i use NON-ECC RAM? So i need a clarification, if not, at least a consensus. To add more to the confusion, some vendors are marketing obvious desktop grade setup as server solutions. Stuff i read on forums is giving me conflicting views, some says ECC RAM is a must, while other says it is optional, as long as it is not extremely high load, availability & sensitive, like banking(where a single mistake could cost a fortune).

To reduce cost and simplify maintainace, im thinking of making a simpler setup and consolidating them all on one device (planning to get a new HW) i have been running these services for a while now (except for dolibarr which is hosted online) on several old destkop grade PCs, NON-ECC memory with little trouble. On top of LAMP ill be running, Owncloud and dolibarr ERP sofware.

What does non ecc memory mean
