Hopefully you can answer this Question I have for newer CPU hardware and North Bridge Chipset conflicts:

Now, Normally, the North Bridge chipset handles all the interaction between the CPU, RAM, Video, and South Bridge. If I wanted to purchase a Motherboard that can handle RAM speeds of "DDR3 2800+(OC)/2400(OC)/2133(OC)/1866(OC)/1600/1333/1066", and I also buy RAM that is DDR3-2800, I should have no issues with compatibility on this specific issue.

However, the new i7 Intel processors have an "Integrated Memory Controller: Dual-channel DDR3 Memory Controller supports DDR3-1333 and DDR3-1600 memory"

So, as I see it, if the i7 processor's integrated memory controller may limit me to DDR3-1600 memory, would the extra spent on DDR3-2800 RAM and Motherboard be wasted? Which takes precedence?

You can set the memory profile on most of these motherboards so you can take higher speed RAM. But you probably won't notice anyway if you dropped to DDR3-1600 unless you have some memory constrained program you're running.

yeah, and treat it just like it's from the northbridge and just moved. There's still nothing really stopping you from running DDR3-2800 at it's advertised speeds besides the BIOS/UEFI settings.
