GPU Upgrade Leads to BIOS Update: The fTPM Reset Question


“Following a BIOS update, I’m prompted to reset the fTPM, although no new CPU has been installed. After adding a new RX 7900XTX GPU and updating drivers, I encountered an error which led me to update the motherboard’s BIOS, which hadn’t been updated since 2020. Now, upon booting, I receive a message about a new fTPM firmware version. Typically, I would reset it if this were a new setup, but the only change made was the GPU; the CPU remains unchanged. Without BitLocker enabled, is it safe to proceed with the reset without risking data loss?”


When you update your computer’s BIOS, you might encounter a prompt to reset the Firmware Trusted Platform Module (fTPM), which can be perplexing, especially if you haven’t made any changes to the CPU. This situation is not uncommon for those who upgrade their graphics processing unit (GPU) to a newer model, such as the RX 7900XTX, and subsequently face driver-related issues that necessitate a BIOS update.

The fTPM is a version of the Trusted Platform Module (TPM) technology implemented in firmware rather than hardware. It serves as a secure crypto-processor that aids in hardware authentication and can enhance the security of the system. When you update your BIOS, the system may detect changes in the hardware configuration or the firmware itself, prompting a reset of the fTPM to ensure that these changes are acknowledged and that the system remains secure.

Is It Safe to Reset?

Resetting the fTPM is generally safe and shouldn’t result in data loss, particularly if you’re not using BitLocker or a similar encryption-based security feature. BitLocker often relies on TPM to secure the encryption keys, and resetting the TPM could render the system unable to decrypt the drive, leading to data inaccessibility. However, since BitLocker is not enabled in your case, this concern does not apply.

Proceeding with the Reset

Before proceeding with the fTPM reset, it’s advisable to back up any important data as a precautionary measure. Although data loss is not expected, having a backup ensures that you’re prepared for any unforeseen circumstances.

Once you’ve secured your data, you can proceed with the fTPM reset. This action will re-initialize the TPM and adapt it to the current BIOS configuration, which now includes your new GPU. After the reset, your system should boot normally, and you can continue to enjoy the enhanced performance of your RX 7900XTX without further complications.


In summary, resetting the fTPM after a BIOS update is a standard procedure that is safe to perform when you’re not using encryption services like BitLocker. It’s a necessary step to maintain the integrity of your system’s security mechanisms. Always remember to back up your data regularly, and you can confidently navigate BIOS updates and fTPM resets with peace of mind.
