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.
