A slower DMI is used to connect Intel's most recent northbridge and southbridge components.
By comparison, Intel's LGA 1156 (Socket H) moves the QPI link and PCI-Express controller onto the processor itself, using DMI to interface a single-component "chipset" (now called PCH) that serves traditional southbridge functions.
In November 2008, Intel released Core i7, which was the first processor requiring this socket.
Socket B processors have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use.
Processors using this socket have a lower static load limit than previous models using LGA 775.
