what would be the best "memory timing" to set my corsair xms pc3700 to for overclocking?

This article will give you a fair idea of things: http://www.lostcircuits.com/memory/ddr400/

tRCD (RAS=>CAS delay/row=>column delay) is usually the most influential value and setting it too aggressively can absolutely kill an overclock. It's also arguably the most significant factor when it comes to actual performance, so it's a bit of a balancing act as to how you set it.
