in the Summary tab it is missing:

I don't know what means the second North bridge:

We will fix that issue in the next AIDA64 beta update ;) 

The secondary IMC is because all Ivy Bridge-E/EP, Haswell-E/EP and Broadwell-E/EP processors include two memory controllers, but in many cases only one of them is utilized.

Fiery
