There is a little memory tester at memtest86.com that I always use on =
new systems. It works a bit like a pregnancy test: if it saysyou have =
memory errors, you have memory errors. If it says no errors, you still =
don't know if you have any.
Memory errors are hard to spot and may require subtle combinations of =
all systems components to crop up. Having said that, I found that most =
systems remain stable if they pass both a night of memtest86 and a make =
-j 8 world.

You can't have everything. Where would you put it?
