Look for wait states. Add a wait state, which slows down access to the ram (if it doesn't help, put it back where it was).

Mixing different types is a bad thing to leave to chance. Corsair and Kingston I *think* are good brands.

Try each memory stick by itself; if it only fails when both are in at once, reverse the slots they are in; if it still fails, get another stick that is the same brand and type as another, try just those together.
