Intel(R) 5 Series/3400 Series Chipset Family PCI Express Root Port 2 - 3B44 Driver

The Intel(R) 5 Series/3400 Series Chipset Family PCI Express Root Port 2 – 3B44 driver helps Windows identify and configure this Intel chipset’s PCI Express connection. It is relevant when restoring an older Intel-based computer, reinstalling Windows, or checking an unrecognized chipset entry in Device Manager. Although listed under Storage, this device is a PCI Express root port rather than a storage controller, so it does not replace drivers for connected drives or other hardware.

Key Features

• Chipset device identification: Intel chipset INF information helps Windows display the appropriate device name and apply the relevant configuration.
• PCI Express integration: Supports recognition of the root port that links downstream PCI Express hardware to the system.
• Legacy Windows compatibility: Intended for compatible systems running Windows 10, 8.1, 7, Vista, or XP, subject to the individual package’s supported platforms and architecture.
• Reinstallation support: Can help resolve missing chipset identification after a clean Windows installation. It is not a guaranteed fix for hardware faults or performance problems.

How to Install Intel(R) 5 Series/3400 Series Chipset Family PCI Express Root Port 2 – 3B44 Driver

1. Confirm the device. Open Device Manager and locate the root port under System devices, or inspect an unidentified device. In Properties > Details > Hardware Ids, check for `PCIVEN_8086&DEV_3B44`.
2. Check compatibility. Before choosing an Intel(R) 5 Series/3400 Series Chipset Family PCI Express Root Port 2 – 3B44 driver download for Windows, verify the package supports your operating system and 32-bit or 64-bit installation. For Windows 10/11 systems, do not assume Windows 11 compatibility; it is not included in the listed supported operating systems.
3. Choose a trusted package. Prefer your computer manufacturer’s chipset package or an applicable Intel release. Select the latest version explicitly supporting your hardware, and use a trusted free download rather than a paid driver-updater utility.
4. Install the package. Extract the files if necessary and run the supplied installer. If only INF files are provided, use Device Manager > Update driver > Browse my computer for drivers, then select the extracted folder.
5. Restart and verify. Restart if prompted, then check the device’s status in Device Manager. If warnings remain, investigate compatibility or connected hardware rather than repeatedly reinstalling.

Keep your chipset package updated when a compatible update addresses a relevant issue or your system manufacturer recommends it. A newer package is not automatically better for an older chipset, and chipset identification updates may not change performance.
