Well, I've even seen expensive memory fail due to static damage. Also, even the best parts have a range that they work in. For example, 5 volt parts actually work in a range of about 4.5 to 5.5 volts. If you have a part that actually wants 5.4 V but only receives 5.39 V, it may *appear* to work correctly most of the time, but if the voltage drops to 5.35 V because of other draws on the system, the part will then appear to have failed. This is even though the part is "within spec." on 1/25/04 6:19 PM, Terry Houle at houle at citilink.com wrote: > It is all standard Apple and has been in there since Jaguar with no > issues.
