Well, about 99% of the time that I encounter a problem that could be caused by RAM in the shop I work at, any Apple RAM installed is good. However, it can go bad; whether by failure over time, or caused by a surge or something similar–even though problems from surges often don't show up for months or years. And of course, problems that can be related to RAM probably account for at least half or two thirds of all repairs; many of them turn out to be something else (and are often more likely to be something besides RAM), but RAM can seriously cause just about any problem. If you have multiple sticks of RAM, try removing one and then the other and see if any of your problems go away; this applies to anybody that is having a lot of crashing, especially if it happens in random applications at random times and is not easily reproducible. cbirds <cbirds at earthlink.net> writes: > The ram is from Apple, was ordered with the machine so it should be OK?
