In-Depth Information
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
nameusedforthesouthbridgecomponentinsupporting5xserieschipsets.TheLGA1156
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 integ-
rated 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
DefinitionMultimediaInterface(HDMI),DigitalVisualInterface(DVI),orVideoGraph-
ics Array (VGA) connectors.
