The Q170 chipset includes TPM 2.0 (Trusted Platform Module) soldered onto the board. This is a critical feature if you are planning to run Windows 11. Unlike many older motherboards that require a TPM header and a separate module, this board has it built-in and enabled in BIOS, making it fully compatible with Windows 11 requirements.

The part number GA0402 is most commonly associated with the OptiPlex 7040 Micro (the tiny pizza-box size).

Note: Always update BIOS only if needed; a failed update can brick the board. If your system is working fine, skipping updates is safe.
