> Is this the seemingly-pointless "memory test" all computers do? I think that the classic case was that the computer wrote and read to/from every memory address to check that the memory reported present was actually there. I'm not positive, but I think that most machines these days do a cut-down version of that to save time. I also think that auto-adjusting the timing is probably a separate process.
