To ECC or Not to ECC . . .

Just found out that our P4C800-E Deluxe MBs can take ECC RAM. Wanted to use them for data backup and syncronizing massive archives of files. No games etc for these.

1. Wondering if it is worth getting ECC RAM? I initially was looking for just ECC and not ECC/Registered but couldn't find any confirmed combatible with this mb. Can anyone confirm any ECC unbuffered that is compatible with this board?

2. Wouldn't the performance hit for registered (buffered) ECC be too much to justify for these tasks? I would think that ECC is enough for what i want to use these for. After all, this is only for syncronizing files and data backup/restore in a small WORKGROUP environment.

Notes: Presently using Corsair non-ecc ram and these systems are absolutely ROCK-SOLID. I somehow feel that ECC would give me more data integrity for these above mentioned tasks. Wouldn't ECC be better to use when backing up and syncronizing files over a small (100 Mbs ethernet) network? Or am i just overly paranoid? Perhaps i should just keep the ram that's in there and not worry about it?

Any comments or help on this is appreciated.

I very much appreciate the heads up on this forum. Don't have a clue as to how I missed it!

Thanks

If the non EEC RAM is working properly I would stick with it. The only advantage with EEC RAM is that it has parity checking but is far more expensive as it only comes as EEC Registered RAM.

Once you try to make the change you'll have to scrap all of the existing RAM as you [b]CAN NOT[/B] mix the two types.

Actually thats not correct. ECC RAM can be both Registered (Buffered) or NON-Registered (Unbuffered).

Yes I know but try to find any [i]NON-Registered (Unbuffered).[/i] No one sells it in the main stream.

You may get it on [b]Special Order[/b] but it's not something that you are going to buy off the shelf. That is the point that I was trying to get across.

You're welcome to try but I must warn you of the differences between a lot of the ECC RAM the cutout is in a slightly different place so quite a lot of it doesn't fit in some EEC Sockets. I currently have a Dual 3.6 Xeon Intel M'Board that I needed some more RAM for and it only works with EEC so I bought some earlier this week that was supposed to be the right Spec and it doesn't fit the M'Board.

The suppliers will only accept it back if I take the M'Board to them so they can find the exact type of EEC RAM that is required seems that the Corsair Spec stuff doesn't fit this M'Board. :^)
