Nah, if it survived an overnight MemTest86 run, that's basically the same tool -- your RAM is OK in isolation. Consider the Prime95 Large FFTs test, though -- could be something in the CPU/RAM interface. At the moment, I'm leaning towards "shitty OEM OpenGL driver," but we should at least rule out hardware and cooling first.
