Scheda di interfaccia Inter-Tech ST-7266 PCIe RJ-45 raffreddamento passivo

The Inter-Tech ST-7266 is an internal PCIe interface card that provides a 2.5G RJ45 network connection for desktop PCs and servers. It uses the Realtek® RTL8125B chipset and includes the ST-7266 co-processor to offload network processing from the main CPU. The card has passive cooling and compact dimensions (120 × 85 × 22 mm), and is compatible with Windows 7, 8, 10, 11 and Windows Server 2012.

Advantages

The built-in Realtek RTL8125B chipset delivers high throughput for gigabit-plus network environments, while the ST-7266 co-processor reduces CPU load during network transfers. Passive cooling provides silent operation without additional fans, and the PCIe host interface ensures broad compatibility with standard desktop and server motherboards. The RJ45 port supports up to 2.5G speeds for faster wired connectivity compared with standard Gigabit NICs.

Suitable for

• Upgrading a desktop PC to 2.5G wired Ethernet
• Small office or home servers needing higher network throughput
• Systems where silent, fanless network hardware is preferred
• Windows-based systems (Windows 7, 8, 10, 11, Server 2012)

How to use

Install the card into an available PCIe slot on the motherboard, secure it to the chassis, and connect a network cable to the RJ45 port. After powering on the system, install the appropriate drivers for your Windows version if they are not auto-detected. Verify the link speed in the operating system network settings to confirm 2.5G operation and configure network parameters as required.

Recommendations

For optimal performance, use category 5e or higher Ethernet cabling and ensure the connected switch or endpoint supports 2.5G. Keep airflow around the passive-cooled card unobstructed to maintain safe operating temperatures.
