NVIDIA GeForce GTX 660 Ti Driver

The NVIDIA GeForce GTX 660 Ti driver lets Windows communicate with your graphics card, enabling proper display output, hardware acceleration, and graphics settings. It is useful after reinstalling Windows, replacing a graphics card, or troubleshooting missing resolution options, display glitches, and software compatibility issues.

Key Features

• Hardware-accelerated graphics: Enables the GPU’s supported DirectX and OpenGL features for compatible games, desktop applications, and multimedia software.
• Display configuration: Provides access to supported resolutions, refresh rates, and multi-monitor settings through the NVIDIA Control Panel.
• Application-specific settings: Lets you adjust options such as anti-aliasing, texture filtering, and vertical synchronization for supported applications.
• Compatibility fixes: Depending on the release, an update may address known graphics problems or improve compatibility with older games and software.

How to Install NVIDIA GeForce GTX 660 Ti Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit in Windows system information. Windows 7, Windows 8, and Windows 10 require a package that explicitly supports both your OS and this GPU.
2. Choose a compatible release. For an NVIDIA GeForce GTX 660 Ti driver download for Windows, check the package’s supported-products list and release notes. This is a legacy Kepler graphics card, so the latest version of NVIDIA’s general driver package is not necessarily compatible. For Windows 10/11 systems, do not assume that a Windows 10 package officially supports Windows 11.
3. Download the installer. Use a trusted source and verify that the free download matches your operating system and card. Avoid unrelated driver utilities or packages intended for newer GeForce models.
4. Install the driver. Close running games and graphics applications, launch the installer, and follow its prompts. If troubleshooting an existing installation, use the clean-install option when available; this resets NVIDIA settings.
5. Restart and verify. Restart your PC if prompted, then check Device Manager and confirm that your display resolution and graphics settings work correctly.

Keep your driver updated within the releases compatible with this card. Because the GTX 660 Ti is a legacy model, ongoing updates are limited; check compatibility before replacing a stable driver, and do not expect newer drivers to add unsupported hardware features.

Common Issues and Fixes

• Install fails/rolls back: GTX 660 Ti is Kepler-based and unsupported by current Game Ready drivers. Download the latest NVIDIA legacy/470-series driver for this card; if setup still fails, remove old drivers with DDU in Safe Mode and retry.
• Device not detected: Reseat the card and PCIe power cable, connect the monitor to the GPU, and set PCIe as primary in BIOS. Check Device Manager for Code 43; reinstall the legacy driver if shown.
• Version conflicts: Remove GeForce Experience and other NVIDIA driver packages, block Windows Update from replacing the driver, then install one matching 470-series package only.
