I used memtest and tested through 5 full tests overnight and found nothing. However running AHT, which I suspect has a smaller memory footprint—and this may be why it catches the problem—it identifies the bad RAM on each pass. Move the module to another slot, and it is found each time. AHT doesn't run as many different types of tests, but it does seem to be useful. I have just identified the opposite scenario.

Same exact situation for a macbook pro - I trust memtest. I had an xserve that passed Apple’s hardware test with flying colors, but memtest found bad memory.

I don't know what does it do for so many time, but I'm sure it's not doing all the tests memtest does. My G5 memory passed all the tests using Apple Hardware Test, but failed with memtest, and it was defenetly damaged, because I had some memory-related problems during the G5 usage.

Get the hardware test disk, Boot from the DVD by holding the 'c' key down, and you will boot into it. I don't know how much base memory it consumes, but it's very little, as it doesn't load but a very basic - (text only no graphics interface). I had some memory questions about my (now) old G5, and used it to exonerate the memory.
