How to Enable TPM 2.0 on a Gigabyte A320 Motherboard
A step-by-step fix for the "This PC can't run Windows 11" error caused by TPM 2.0 being switched off in BIOS on Gigabyte A320 boards.
Quick answer: On a Gigabyte A320 board, TPM 2.0 is built into the AMD CPU as "fTPM." Enter the BIOS (press F12 at startup, then click Enter Setup), go to Peripherals → AMD CPU fTPM, switch it from Disabled to Enabled, then press F10 to save and exit. No extra hardware is needed.
What is TPM 2.0 and why does Windows 11 need it?
TPM (Trusted Platform Module) is a security chip — or in this case, a security function built into the processor — that stores encryption keys and supports features like BitLocker and Windows Hello. Microsoft requires TPM 2.0 as a minimum specification for Windows 11, so if it's switched off in the BIOS, the installer will block the upgrade or show a "This PC can't run Windows 11" message, even on otherwise compatible hardware.
Do I need to buy a TPM module for a Gigabyte A320 board?
No. Every AMD Ryzen CPU since the 2000 series includes a firmware TPM (fTPM) built into the chip itself. On Gigabyte A320 boards this is exposed in the BIOS as AMD CPU fTPM and just needs to be switched on — there's no separate module to buy or fit.
Restart and enter BIOS
Turn on your PC and repeatedly press the F12 key as it boots to bring up the boot menu, then click Enter Setup to open the BIOS. This is more reliable than pressing Delete, which can be easy to mistime.
Navigate to AMD CPU fTPM
Go to the Peripherals tab, then look for AMD CPU fTPM — you'll see it listed as Disabled by default.
Enable the setting
Select AMD CPU fTPM and change the option from Disabled to Enabled.
Save and exit
Press F10 to save your changes and exit the BIOS menu. Your PC will restart automatically.
TPM 2.0 is now enabled
Windows should now detect a valid TPM 2.0 module and allow installation or upgrade to Windows 11.
How do I check TPM is working after enabling it?
Once Windows has restarted, press Windows key + R, type tpm.msc, and press Enter. The TPM Management console should report "The TPM is ready for use" along with Specification Version: 2.0. If Windows 11's PC Health Check tool previously flagged your device, re-run it to confirm the TPM requirement now passes.
AMD CPU fTPM is greyed out or missing — what now?
This is usually a BIOS version issue rather than a hardware fault. Update the motherboard BIOS to the latest version from Gigabyte's support site for your exact model, then check the Peripherals tab again. If the option is still missing after a BIOS update, the board may be too old to support fTPM and could need a physical TPM header module instead (check your motherboard's specification page to confirm whether it has one).
Frequently asked questions
Does every Gigabyte A320 motherboard support TPM 2.0?
Yes, as long as it's paired with an AMD Ryzen CPU that includes fTPM (Ryzen 2000 series or newer). The BIOS needs to be reasonably up to date to expose the setting.
Will enabling fTPM affect my existing files or installed programs?
No. Enabling fTPM in BIOS doesn't touch your files, settings, or installed software — it only switches on the security function needed for Windows 11 and features like BitLocker.
Why does Windows 11 still say TPM isn't supported after I enabled it?
Double-check you enabled it under Peripherals → AMD CPU fTPM rather than a similarly named setting elsewhere, and confirm via tpm.msc that it reports version 2.0. A BIOS update can also resolve detection issues on older firmware.
