Awhile back I reported random crashes.

Testing memory for hours on-end using the latest version of Memtest86
found nothing.

With some time on my hands this week, I pulled the machine out,
swapped out the second bank of memory... problem solved.

Aaaaargh!

Is there a REAL memory test out there?

Memory testing programs don't always test the memory in the
all its failing.
it could be a specific order of bit values and address
location change rate that causes the memory to fail.
I've seen a very unique tester module that have an elevation
board that plugs into your memory socket. you then plug your
original back into this carrier board which has enough memory
already on it to accommodate with what your testing.
You run the PC for a while to wait for a crash, if an error
in memory occurs, an LED on this module lights up with a mini
LCD display giving you the address and byte values of the failure.

Basically, as the bus is addressing your memory via the jumper
card, the onboard memory is also being written to and then compared
with your memory at some point to test for verification of integrity.

this is suppose to be a better test to insure the memory is working
correctly in your MB with the settings you have selected. It does not
mean the memory is permanently bad. it just may not be able to operate
at the speed of your settings.
