HP Crd Dual TBT4 PCIe x4 LP interface cards/adapter Internal

The HP Crd Dual TBT4 PCIe x4 LP is an internal adapter engineered to add dual Thunderbolt 4 connectivity to compatible systems. It uses a PCIe host interface and provides a PCIe output interface for high-bandwidth device connections. Built to fit low-profile cases, the card measures 121 mm in width, 25.3 mm in depth and 144 mm in height, and has a green-and-silver finish that integrates with standard server and workstation interiors.

Advantages

This internal adapter supports PCIe-based host and output interfaces to enable fast data transfer and low-latency peripheral communication. Its low-profile form factor and compact dimensions make it suitable for small or space-constrained chassis. The dual Thunderbolt 4 capability allows connection of multiple high-speed devices while preserving PCIe lanes for storage and expansion. The lightweight construction and standardized interfaces simplify installation and compatibility verification with modern motherboards.

Suitable for

• Upgrading workstations or compact servers with dual Thunderbolt 4 ports
• Connecting high-speed external storage and professional peripherals
• Environments where low-profile expansion cards are required
• Systems needing additional PCIe output for expansion devices

Key specifications

How to use

Power down the system and disconnect mains power before installing the adapter. Insert the card into an available PCIe x4 (or compatible) slot on the motherboard, secure it to the chassis with the appropriate bracket or screw, and reconnect power. After booting, verify that the system firmware recognizes the adapter and install any required drivers or platform software provided by the system or HP to enable Thunderbolt 4 functionality. Configure connected devices through the operating system’s device settings or Thunderbolt management utility as needed.

Recommendations

For optimal performance, install the adapter in a full-length motherboard slot that provides sufficient PCIe lanes and ensure system BIOS/UEFI and operating system are updated. Use shielded and certified Thunderbolt cables and high-quality peripherals to maintain signal integrity. Avoid placing the card near sources of excessive heat or strong electromagnetic interference to preserve stability.
