Interfaces

40 Datasheet, Volume 1

2.4.4 Multi Graphics Controllers Multi-Monitor Support

The processor supports simultaneous use of the Processor Graphics Controller (GT) and

a x16 PCI Express Graphics (PEG) device.

The processor supports a maximum of 2 displays connected to the PEG card in parallel

with up to 2 displays connected to the processor and PCH.

Note: When supporting Multi Graphics Multi Monitors, “drag and drop” between monitors and

the 2x8 PEG is not supported.

2.5 Platform Environment Control Interface (PECI)

The PECI is a one-wire interface that provides a communication channel between a

PECI client (processor) and a PECI master. The processor implements a PECI interface

to:

• Allow communication of processor thermal and other information to the PECI

master.

• Read averaged Digital Thermal Sensor (DTS) values for fan speed control.
