Intel Q67 Express Chipset Family LPC Interface Controller 1C4E Driver

The Intel Q67 Express Chipset Family LPC Interface Controller 1C4E driver helps Windows correctly identify the LPC controller in systems built around Intel’s Q67 chipset. It is relevant if you have reinstalled Windows, see an unidentified chipset device in Device Manager, or need to restore the appropriate Intel chipset identification files. Although sometimes listed under Audio, this device is a chipset component, not a sound controller, and its driver does not replace your audio driver.

Key Features

• Correct device identification: Supplies chipset information that helps Windows display the controller’s proper name and associate it with the appropriate system support.
• LPC interface recognition: Identifies the chipset component associated with low-speed and legacy platform functions.
• Useful after a Windows reinstall: Can resolve missing device identification when the correct chipset INF files are absent.
• System-specific compatibility: Driver selection depends on your motherboard or PC model and Windows release. For Windows 11, 10, 8, and 7, verify the package’s stated compatibility; older Q67 hardware may lack official support for newer operating systems.

How to Install Intel Q67 Express Chipset Family LPC Interface Controller 1C4E Driver

1. Confirm the device. Open Device Manager, locate the controller or unidentified device, and check Properties > Details > Hardware Ids. Look for the identifier PCIVEN_8086&DEV_1C4E.
2. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11, do not assume an older chipset package provides official compatibility.
3. Choose a verified package. Before starting an Intel Q67 Express Chipset Family LPC Interface Controller 1C4E driver download for Windows, compare the package details with your PC manufacturer’s recommendations. Select the latest version that explicitly supports your system, using a trusted free download source.
4. Install the chipset package. Extract the files if necessary, run the included installer, and follow its instructions. If only INF files are supplied, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and verify. Restart if prompted, then check Device Manager for the correct device name and any remaining warning icons.

Keep your chipset driver information current by checking for a compatible update when troubleshooting or reinstalling Windows. A newer INF package may improve identification without changing performance, so prioritize manufacturer-approved compatibility over version numbers alone.

Common Issues and Fixes

• Install fails or says “not supported”: Verify you downloaded the Intel Chipset Device Software for Q67 and matching Windows architecture (x64 vs x86). Run the installer as administrator; avoid forcing a generic LPC driver manually.
• Device not detected / shows as unknown PCIVEN_8086&DEV_1C4E: Install the chipset INF package first, then reboot. In Device Manager, enable Show hidden devices to check for a ghosted LPC controller entry before rescanning hardware.
• Version conflicts, Code 10, or old OEM INF: Uninstall the device and remove stale Intel chipset INF packages with `pnputil /enum-drivers` and `pnputil /delete-driver`, reboot, then install the latest OEM-approved Intel chipset package. Do not mix drivers from different chipset generations.
