Yanking half the memory isnt something I would expect to effect what
you are trying to measure - except to make the test results MORE
valid, although it does require a pair of reboots (assuming you put it
back in). Odds are that gig is on more than one stick :-)

On another note, why exactly is it that a 32bit system limits one to
2GB files, rather than 4GB files? Whos bright idea was it to use a
signed integer rather than an unsigned one to point to a location in a
file, anyways?
