(Somewhat contradicting my previous statement:)1: The lifetime was shortened by the swift replacement after detected errors.  I would expect most users to not detect most of these errors in the first place, and even if detected not count the DIMM as faulty.2: "Lifetime" warranty makes me a bit suspicious.  It all depends on interpretation.  One way of interpreting it is to say: "So, the DIMM is dead?  Then it's life, and thus lifetime warranty, is over!"Being a bit less harsh one can still argue that it's only normal and expected behaviour from an older DIMM to cause data errors once in a while. In the test there were very little hardware problems.  Just corrupted data in the databases, which is much worse if the data is for example the amount of money present on a bank account. The OS can't tell if the provided input data is correct or not. Which suggests your DIMMs were in very bad shape. Even in the test quite a few DIMMs were replaced early on, but those that "survived" the first couple of months without problems usually lasted the entire test period. CheersOlle
