Intel Desktop Board DG43NB Product Guide NOTE System resources and hardware (such as PCI Express) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1 GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system. Go to the following locations for more information about: • SDRAM specifications, http://intel.com/technology/memory/ • Installing memory, page 34 in Chapter 2 • Tested memory, http://cmtlabs.com/mbsearch.asp Intel® G43 Express Chipset The Intel G43 Express Chipset consists of the following devices: • Intel G43 Express Chipset Graphics and Memory Controller Hub (GMCH) with Direct Media Interface (DMI) • Intel 82801JB I/O Controller Hub (ICH10) with DMI The GMCH component provides interfaces to the processor, memory, PCI Express, and the DMI interconnect. The component also provides integrated graphics capabilities supporting 3D, 2D, and display capabilities. The ICH10 is a centralized controller for the board's I/O paths. For more information on the Intel G43 Express Chipset go to http://developer.intel.com/products/chipsets/ Intel G43 Graphics Subsystem The Intel G43 Express Chipset contains two separate, mutually exclusive graphics options. Either the integrated Intel Graphics Media Accelerator X4500 (GMA X4500) graphics controller is used or a PCI Express x16 add-in card can be used. The GMA X4500 graphics controller supports dual independent displays via the VGA and DVI-D connectors on the Desktop Board back panel. When a PCI Express x16, x8, or x4 add-in card is installed on the Desktop Board, the Intel GMA X4500 graphics controller is disabled. 14
