Whenever we talk about ECC RAM, we talk about 99.9999999% of people not needing it. I'm curious to see if anyone here actually needs it, and for those that do (if any), what software they use that needs ECC RAM. For my own part I don't need it at all. Yet when I replaced my RAM, I replaced it with ECC RAM anyway. I can't really say why other than it's the "proper" RAM for a MP and I like the concept of self-correcting RAM. For the purposes of this poll, I'd like to be generous in the definition of ECC RAM. ECC RAM can be ECC system RAM, ECC GPU RAM, a software emulated ECC function that uses non-ECC RAM (as is often the case with workstation video card drivers), or anything else that can reasonably be argued to serve the same function. In other words, the point is not about how the function is accomplished, but whether or not you need/want the function.
