Looking to get some more out of my RAM

[asdf123]

I have a 6x2gb kit of standard corsair xms3 1600MHz ram rated at 1.60v, picture below. it's a
CM3X2G1600C9B6, cpu z below. i currently have an overclock on my i930 @ 4GHZ 20x200, what do you guys think i should run my ram at and what timings?

I'm sure those timings could go down to 8-8-8-24, or try bumping your speed up to 1866.

And what boost did going from 9 to 8 actually give you?
