This a discrete TPM 2.0 module for desktop PC motherboards. It has an ultra-compact horizontal form, so it won't clash with other components (e.g. your video card), or cables. Generally, discrete TPM module solutions are more reliable than fTPM solutions. Also, they can help you avoid some weird problems people have experienced with fTPM, such as: 1. Encryption Key data get wiped out during BIOS updating. 2. Credential info lost or invalidated after CPU upgraded or replaced (even happens when replacing old CPU with a same model one). 3. Random CPU stuttering or performance issues, especially on Windows 11 and for Ryzen 5000 series CPU. Installation: You can easily install the moudle by your self with only a few steps. Power off your PC, then plug TPM module into your motherboard. Power on PC, enter BIOS, and enable TPM 2.0 options. Reboot into Windows, and Windows will do the rest work for you. Windows performs then initialization and configuration works in the background silently, and you don't need to do anything. Must-see requirements before placing an order: Please make sure your motherboard supports TPM 2.0 module You can check your compatibility and incompatibility with this motherboard module The first step: first confirm your own motherboard manufacturer, divided into for Intel and for AMD. If it is for Intel, please check the number after the English letter. Any number greater than 99 (including 99) is fine, for example: for ASUS X99, 99 after x is fine. If it is for AMD, make sure that the memory type of the motherboard must be DDR4. For example: MSI 970A-G43, the memory type of this model is DDR3, which is not supported! The second step is to confirm the pins of your motherboard, whether it is 12pin, 14pin or 20pin, etc. Note:Due to different production batches, the printing silk screen/appearance is different, which does not affect the use.
