I'd like to reassure myself that my new RAM in my MacBook is solid like a rock. So I want to put it through a gauntlet of tortures. What's the best way to test it? I also can use Windows (obviously) or any of the Linuxes, so if there's better RAM testing tools on those OSes, do mention them! (And I say NO to Rember, one of the crappiest software out there, so don't recommend that).
