One thing to consider is that I don't think anyone has provided any real
'proof' that Apple's RAM is any better than Crucial's, etc.. I've been
reading phrases like: "So and so said...", "My Apple repair person said...".
This is like the floppy disk issue. Do you recall that there were cheap floppies and expensive ones (12 years ago or so), somewhat like there are 4x CDR disks, and 16x, etc. I imagined that the expensive ones were made with superior materials, better machinery, etc. But I think they are all made the same, but the ones that could stand up to testing were the expensive ones.
Actually its exactly the same thing with chips. What distinguishs a 1.8 mhz G5 chip from 2.5 mhz G5 chip? They are exactly identical.. its just that the 1.8 failed when they tried to run it at 2.5.
So this testing issue pervades the computer world. And while Apple is so far out of line with thier prices that its unbelievable on one hand, you can probably imagine that the ram makers just turn out stuff as fast as they can, sell it cheap, if its messed up, then they rely on you to find this out in the way of crashes, and then try to pin it on them, and in the worst case they give you a new ram as a replacement .... to test for yourself.
