Just thought this was useful to post as i posted at another forum asking about it
why ECC ram ?

Q: What's ECC RAM, and should I buy it?
A: Error-Correcting-Code RAM modules have special circuitry that corrects memory errors on the fly. They're used primarily in servers and high-end workstations. ECC SDRAM will work in non-ECC motherboards, but you won't get the benefit of the ECC circuitry, so it doesn't make sense to pay the extra cost.

First of all, what does ECC stand for?
"ECC" stands for "Error Checking and Correction".
And, what is "Error Checking and Correction"?
Error Checking and Correction refers to a technology which allows a computer system to operate even if a memory error occurs.
Why do ECC modules cost more than modules without ECC?
In order to check and correct the memory, additional RAMs are required. A non-ECC module which has eight RAMs would need to have a ninth RAM added; a sixteen RAM module would generally need to have TWO additional RAMs added. Obviously, the additional RAMs make the module more expensive.
So it's kind of like the old parity modules, right?
Well, kind of, but ECC is a WHOLE LOT more useful. The ECC technology used on most x86-architecture PCs and servers is capable of correcting errors, where parity can only detect errors. If you've ever had an error "detected" on your system, you know the result - the blue screen of DEATH! Really useful, huh... With ECC you would sail right through, without crashing or even interrupting normal operation. Much more useful!
