memtest86 reliably locked up in the first 5 minutes (beginning of the 3rd test--or fourth?--of the basic suite), after reporting errors at two locations in the first tests. As I posted in the other thread, the errors stayed in the same location when I swapped out the memory dimm so I suspected a MB problem. But, their test completed and reported no errors, and they wouldn't test memtest86 on any in-house system. So basically I started out with higher faith in memtest86 than in Dell quality and they wouldn't going to lift a finger to confirm or dispel that. Maybe they didn't have much faith in their hardware either. :0
