What do the tests mean in memtest

Okay guys here's one for you.

Been burning in some ram on a number of dfi boards and need your help.

What does it mean if I get errors on tests 3,4 and 6?

I know if I pass 5 and 8 its normally bench stable but do errors on these other tests relate to some other component issues?

I'm not sure what the individual tests mean but I don't trust memtest at all. I fail it even at stock yet I can pass two instances of prime 95 & two instances of superpi32m simultaneously.
