The AGP connector supports either: 
•  1x, 2x, or 4x AGP add-in cards with 1.5 V I/O 
•  AGP Digital Display (ADD) cards

•  The AGP connector is keyed for 1.5 V AGP cards only.  Do not attempt to install a legacy 

The GMCH routes two 12-bit multiplexed DVO ports that are each capable of driving a 165 MHz 
pixel clock to the AGP connector.  The DVO ports can be paired for dual channel mode.  In dual 
channel mode, the GMCH is capable of driving a 24-bit 330 MHz pixel clock.  When an AGP add-
in card is used, the Intel Extreme Graphics controller is disabled and the AGP connector operates 
in AGP mode.  When an ADD card is detected, the Intel Extreme Graphics controller is enabled 
and the AGP connector is configured for DVO mode.  DVO mode enables the DVO ports to be 
accessed by an ADD card.  ADD cards can support up to two display devices with the following 
configurations: 
•  TV-Out 
•  Transition Minimized Differential Signaling (TMDS) 
•  Low Voltage Differential Signaling (LVDS) 
•  Single device operating in dual channel mode 

# 

•  Synchronous display is not supported when one of the display devices is a TV. 
•  Digital Visual Interface (DVI) support is present only when an ADD card is installed.
