The only way it would NOT work would be if one of the sticks didn't play nice with the motherboard. Incompatibility would be the only way it won't work. And obviously overclocking will be difficult or impossible. Same with getting rated speeds. It WILL work fine though once you manually set everything.
True as well as I have done that my self, but in the end as always the weakest link is what will hold you back. And what i ment about them not working would be taking a 1333 and 1600mhz chips and trying to get them to run at 1600mhz. Of course results may vary depending on the IC of the ram. But yes I did leave that part out about running higher spec'd ram at lower speeds, only ram i had issues with doing that with was laptop ram and the good ole SD-Ram.
I personally have only had an issue with ram compatibility and that was with a DFI CFX3200 939 socket, now that was a picky freaking board.Edited by terraprime - 8/23/13 at 12:14am
