I just ran the Crucial memory test on it, and it says that it can take 2gb, but their site only offered me 2 x 512mb, which is what it already has. They don't say why.
What I think that they're saying is that it can be pushed to 2 gb, but they aren't prepared to give a warranty. Oddly, my current machine is much older and uses 200mhz RAM, but went to 2g without any hassle.
Anyone got any thoughts on this? Are Crucial just being ultra-cautious, or is there some extra risk of failure with this type of memory?
