Intel Desktop Board DP43TF 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® P43 Express Chipset The Intel P43 Express Chipset consists of the following devices: • Intel P43 Express Chipset Memory Controller Hub (MCH) with Direct Media Interface (DMI) • Intel 82801JB I/O Controller Hub (ICH10) with DMI The MCH component provides interfaces to the processor, memory, PCI Express, and the DMI interconnect. The ICH10 is a centralized controller for the board's I/O paths. For more information on the Intel P43 Express Chipset go to http://developer.intel.com/products/chipsets/ Graphics Support The board supports an add-in PCI Express discrete graphics card via the PCI Express 2.0 x16 connector as follows: • Supports PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (500 MB/s total). The maximum theoretical bandwidth on the interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when operating in x16 mode. • Supports PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (1000 MB/s total). The maximum theoretical bandwidth on the interface is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when operating in x16 mode.
