Wow! Not many people get the concept of LGA-1156 AT ALL!



The green rectangle shows denotes processor package. There are two separate dies under the IHS of a Lynnfield, one CPU die, and a northbridge die. QPI connects the two. So Lynnfield DOES use QPI.

Since the NB is inside the CPU chip package, PCI-E devices connect directly to the chip package. DMI is not a system interface!
