Running different kinds of RAM?

[MrScottRocks]

My computer came with 4 gigs of Corsair Dominator DDR3 1600 RAM. I bought 4 more gigs of Gskill DDR3 1333 RAM. Obviously it works fine, but i want to get the best performance. How do I set the best timing, etc for these 2 different kinds of RAM? Thanks!

On most Motherboards I'm familar with, the presence of the 1333 RAM will reduce the the 1600 RAM to that 1333 speed. So that's something to consider.

For best chances of an answer, post info on the exact model of M/B you have, and links to its website and links to specs on both RAM modules.
