When I got my dual AthlonMP system, I had a hell of a time getting
it stable.  There were one particular stick of RAM it just would
run with.

I tried underclocking, extra cooling, rearranging ram sticks you
name it, but always the same result.

Then I flashed to the latest BIOS, and it's been stable as a rock
since then.

The BIOS update had no mention of anthing even remotely in that
area.

So, if nothing else, make sure you have your BIOS up to date.
