Must-see requirements before placing an order: Please make sure your motherboard supports TPM 2.0 module. Provide the motherboard model (typically located above the graphics card slot) and socket photo, as there is no fixed specification for this interface and many variations exist. Check compatibility with your motherboard. Step 1: Confirm your motherboard chipset, Intel or AMD. For Intel chipsets, check the number following the letter. Any number 99 or higher is compatible (e.g., ASUS X99). For AMD chipsets, ensure the motherboard uses DDR4 memory. Models with DDR3 memory are not supported (e.g., MSI 970A-G43 is incompatible). Step 2: Confirm the pin configuration on your motherboard, such as 12-pin, 14-pin, or 20-pin. Example: ASUS B450-M motherboard - Chipset: AMD - Memory type: DDR4 (compatible) - Specification: 20-pin Packing list: 1 x module
