Intel Desktop Board DP965LT Product Guide

Power Management Features

Power management is implemented at several levels, including:

Software support through the Advanced Configuration and Power Interface (ACPI)

Hardware support:

Power connectors

Fan headers

LAN wake capabilities

Instantly Available PC technology (Suspend to RAM)

+5 V standby power indicator LED

Wake from USB

Wake from PS/2 keyboard/mouse

Power Management Event signal (PME#) wakeup support

WAKE# signal wake-up 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

ATX12V-compliant power supplies can turn off the computer power through system control. When an ACPI-enabled computer receives the correct command, the power supply removes all non-standby voltages.

When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (either on or off). The computer’s response can be set by using the Last Power State feature in the BIOS Setup program’s Boot menu.

The desktop board has two power connectors. See Figure 25 on page 49 for the location of the power connectors.

Fan Headers

The function/operation of the fans is as follows:

The fans are on when the computer is in the ACPI S0 state.

The fans are off when the computer is in the ACPI S3, S4, or S5 state.

Each fan header is wired to a tachometer input of the hardware monitoring and control device.

All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.

All fan headers have a +12 V dc connection.

The desktop board has a 4-pin processor fan header, and a 4-pin and two 3-pin chassis fan headers.

DP965LT specifications

The Intel DP965LT is an advanced motherboard designed for the Intel Core 2 processor family, notable for its balance of performance, features, and reliability. Launched in the mid-2000s, it was particularly favored by enthusiasts and professionals looking for a powerful yet cost-effective solution for their computing needs.

At the heart of the DP965LT is the Intel P965 Express chipset, which plays a crucial role in facilitating strong data throughput and supporting high-performance components. One of its primary features is the LGA 775 socket, allowing users to install a broad array of Intel processors, including core 2 duo, quad, and Pentium series CPUs. This versatility makes it an appealing option for users aiming to upgrade their systems.

The motherboard supports dual-channel DDR2 memory, with four DIMM slots capable of accommodating up to 8 GB of RAM. This functionality ensures enhanced memory bandwidth, critical for multitasking and memory-intensive applications, effectively making it suitable for both gaming and professional workloads.

Another noteworthy feature is the integrated Intel Graphics Media Accelerator 3000, which allows for basic graphics processing duties without requiring a dedicated GPU. This makes the DP965LT a viable option for users who may not require extreme gaming performance but still need solid visual capabilities for general use. For those who seek enhanced graphics performance, the board also offers an open PCI Express x16 slot for enthusiasts to install high-end graphics cards.

Connectivity options are plentiful, including six SATA II ports, which provide high-speed storage options and support for RAID configurations, allowing users to enhance data redundancy and performance. Additionally, the motherboard includes multiple USB 2.0 ports, a legacy parallel port, as well as an onboard Ethernet controller for seamless networking capabilities.

The DP965LT also incorporates Intel's Active Management Technology, which allows for remote management and system diagnostics, making it suitable for corporate environments where IT administrators require the ability to oversee and maintain multiple machines efficiently.

Another hallmark of the DP965LT is its form factor, which is ATX. This design not only allows for easy installation in a variety of cases but also facilitates better airflow and cooling solutions, important for maintaining system stability during heavy usage.

In summary, the Intel DP965LT motherboard stands as a reliable and powerful choice for users seeking a balance of performance, expandability, and features in their computing setup, making it a lasting legacy in Intel's motherboard lineup.
