Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 20 on page 39 for the location of the chassis intrusion header.

Power Management Features

Power management is implemented at several levels, including:

Advanced Configuration and Power Interface (ACPI)

Hardware support:

Power connectors

Fan connectors

Suspend to RAM (Instantly Available PC technology)

Wake from USB

Wake from PS/2 keyboard/mouse

PME# wakeup support

ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support.

Power Connectors

The desktop board has two power connectors. See Figure 22 on page 43 for the location of the power connectors.

Fan Connectors

The desktop board has three fan connectors. One processor fan header (4-pin) and two chassis fan headers (3-pin). See Figure 21 on page 42 for the location of the fan headers.

Fan Speed Control (Intel® Precision Cooling Technology)

Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor thermal diode temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds.

The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control remain enabled (default BIOS setting) when using the processor fan heat sink included with Intel® boxed processors. Disabling the chassis fan speed control results in chassis fans always

D945GPM specifications

The Intel D945GPM is a motherboard that was designed primarily for desktop PCs and is part of Intel's 9-series chipset family. Launched in the mid-2000s, this motherboard has gained recognition for its robust performance and solid feature set for users seeking a stable and efficient computing platform.

One of the hallmark features of the D945GPM is its support for Intel's LGA 775 processor socket. This accommodates a variety of processors, including the Pentium 4, Pentium D, and the Core 2 Duo series. The motherboard supports dual-channel DDR2 memory, with a maximum capacity of 4GB, providing sufficient memory bandwidth for most basic computing tasks and multitasking needs.

The D945GPM is built on the Intel 945G chipset, which integrates the graphics controller, simplifying the motherboard's design and enhancing efficiency. The integrated Intel Graphics Media Accelerator 950 allows users to perform casual gaming, video playback, and standard office applications without the need for a discrete graphics card. However, for those requiring higher 3D performance, the motherboard includes a PCI Express x16 slot, enabling the installation of dedicated graphics cards.

Additionally, the D945GPM features several connectivity options. It includes support for up to four SATA 3.0 Gb/s connections, which allows users to connect multiple hard drives or SSDs for improved data transfer rates and storage capabilities. There are also four USB 2.0 ports available, providing connectivity for peripheral devices like keyboards, mice, and external storage.

The motherboard integrates an Intel High Definition Audio subsystem, delivering clear and crisp audio quality for an enhanced multimedia experience. The Realtek ALC888 audio codec contributes to decent sound performance for gaming, movie watching, and music playback.

User-friendly features include a BIOS that supports a wide range of customization options, allowing enthusiasts to tweak and optimize performance settings. The motherboard is also equipped with multiple fan headers, enabling efficient cooling setups to maintain stable operation during intensive tasks.

Overall, the Intel D945GPM motherboard stands out for its balance of performance, features, and reliability, making it an excellent choice for basic computing, light gaming, and media consumption, reflecting the tech standards of its time.
