Figure 3.13. Socket LGA1156 (Socket H).
Because the processor includes the chipset North Bridge, Socket LGA1156 is designed to interface
between a processor and a Platform Controller Hub (PCH), which is the new name used for the South
Bridge component in supporting 5x series chipsets. The LGA1156 interface includes the following:
•
PCI Express x16 v2.0
—For connection to either a single PCIe x16 slot, or two PCIe x8 slots
supporting video cards.
•
DMI (Direct Media Interface)
—For data transfer between the processor and the PCH. DMI
in this case is essentially a modified PCI Express x4 v2.0 connection, with a bandwidth of
2GBps.
•
DDR3 dual-channel
—For direct connection between the memory controller integrated into the
processor and DDR3 SDRAM modules in a dual-channel configuration.
•
FDI (Flexible Display Interface)
—For the transfer of digital display data between the
(optional) processor integrated graphics and the PCH.
When processors with integrated graphics are used, the Flexible Display Interface carries digital
display data from the GPU in the processor to the display interface circuitry in the PCH. Depending
on the motherboard, the display interface can support DisplayPort, High Definition Multimedia
Interface (HDMI), Digital Visual Interface (DVI), or Video Graphics Array (VGA) connectors.
Socket LGA1366
Socket LGA1366 (also known as Socket B) was introduced in November 2008 to support high-end
Intel Core i Series processors, including an integrated triple-channel DDR3 memory controller, but
