3.2Mechanical Form Factor

Theory of Operation—Intel®945GME Express Chipset

3.2Mechanical Form Factor

The evaluation board conforms to the ATX form factor. For extra protection in a development environment, you may want to install the evaluation board in an ATX chassis. Internal and rear panel system I/O connectors are described in Section 3.4.3. An overview of connector and slot locations is provided in Section 4.0.

3.3Thermal Management

The objective of thermal management is to ensure that the temperature of each component is maintained within specified functional limits. The functional temperature limit is the range within which the electrical circuits can be expected to meet their specified performance requirements. Operation outside the functional limit can degrade system performance and cause reliability problems.

The development kit is shipped with a fansink thermal solution for installation on the processor. This thermal solution has been tested in an open-air environment at room temperature and is sufficient for evaluation purposes. The designer must ensure that adequate thermal management is provided for any customer-derived designs.

3.4System Features and Operation

The following sections provide a detailed view of system features and operation. Refer to Figure 2 and Table 7 for the location of the major components of the platform.

The Intel® 945GME Express Chipset features the 82945GM Graphics Memory Controller Hub and the Intel® I/O Controller Hub (ICH7-M).
