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'.
