So, I hear what you are saying. But, on the other hand, I have been using 2 non-ECC desktops for a workstation/server for the past ~6 years.. and I would be hard pressed to come up with a single situation where either of the machines randomly crashed or applications did anything 'unexpected' (to my knowledge, of course).

My point is, when you say there is a "96% chance of having an error in THREE DAYS", one would EXPECT to be having issues like.. all the time? So I'm not disagreeing with you, but with the amount of non-ECC machines all over the world and how insanely stable modern machines are, it still seems like a very low risk.

Now of course I agree that if you want to take every precaution, go ECC, but simple observation prove that this "problem" can't be as bad as the numbers are saying.
