For his purpose of stress testing the memory: make -j64 buildkernel I use this on dual proc boxes, maybe -j32 is already more than enough for a single cpu. Won't work with less than 128MiByte RAM iirc, but so far I haven't seen something different that puts that much stress on your memory. Surviving this two or three times in a row you can label your RAM `non-faulty'.
