Intel® 945G Express Chipset for Embedded Computing Overview
The Intel® 945G Express chipset delivers new, innovative features for interactive clients and many other embedded computing solutions requiring enhanced graphics capabilities. These new advancements, which expand on the capabilities of previous Intel® chipsets, include dual-channel DDR2-667 memory technology, Intel® Graphics Media Accelerator 950 (Intel® GMA 950), enhanced manageability and storage security technologies with Intel® Active Management Technology¹ (Intel® AMT), and Intel® Matrix Storage Technology².
Designed for, and validated with, the Intel® Pentium® 4 processor 551 and 651 with Hyper-Threading (HT) Technology+ and the Intel® Celeron® D processors 341Δand 352 - all with Intel® Extended Memory 64 Technology§ (Intel® EM64T) - the Intel 945G Express chipset platform provides scalable performance and is an ideal price/performance solution for embedded computing applications.
The Intel 945G Express chipset consists of the Intel® 82945G Graphics and Memory Controller Hub (GMCH) and the Intel® ICH7/ICH7R I/O Controller Hub (ICH). It delivers outstanding system performance through high-bandwidth interfaces such as PCI Express* x16 graphics or I/O, PCI Express x1 I/O ports, next-generation Serial ATA (SATA II), and Hi-Speed USB 2.0 connectivity.
The new graphics core, combined with the Intel high-performance dual-channel memory interface, can deliver significant graphics performance over previous Intel platforms. With support for dual independent display, enhanced modes for widescreen flat panels, and optimized 3D, embedded platforms based on the Intel 945G Express chipset can deliver an intense, realistic visual experience without requiring a separate graphics card.

¹ Intel® Active Management Technology requires a system with an Intel® 945G Express Chipset, Intel® PRO/1000 PM network connection and appropriate third-party software. The system must be plugged into a power source and connected to a LAN.
² Intel® Matrix Storage Technology requires a motherboard with the Intel® 82801FR (ICH6R) or Intel® 82801GR (ICH7R) I/O Controller Hub System. The system must also have the RAID controller in the BIOS enabled and the Intel Matrix Storage Technology software driver installed. Please consult your system vendor for more information.
³ Media Expansion Cards (MECs) are provided by third-party manufacturers. In addition, utilizing a MEC requires a system equipped with an Intel® 945G Express chipset.
4 Intel® High Definition Audio requires a system with the Intel® 945 or Intel® 915 Express Chipset and a motherboard with an appropriate codec and the necessary drivers installed. System sound quality will vary depending on the codec, drivers and speakers.
5 Valid for ICH7R only.
+ Look for systems with the Intel® Pentium® 4 Processor with HT Technology logo which your system vendor has verified utilize Hyper-Threading Technology. Performance will vary depending on the specific hardware and software you use. See www.intel.com/products/ht/hyperthreading_more.htm for information.
Δ Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/products/processor_number/ for details.
§ Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be available. See www.intel.com/technology/intel64/ for more information including details on which processors support Intel EM64T or consult with your system vendor for more information.
