Select Language:

Are you looking to upgrade the TPM (Trusted Platform Module) on your HP Z440 Workstation from version 1.2 to 2.0? If so, you’ve come to the right place! This simple guide will walk you through the steps to successfully complete the upgrade, ensuring your system is secure and up-to-date.

Step-by-Step Guide to Upgrade TPM 1.2 to TPM 2.0

1. Download the Required Software
   Start by downloading the software package needed for the upgrade. You can find it on the HP support page. Look for the link that specifically mentions the HP Z440 Workstation. Here’s the direct link you’ll need: TPM Security Update. The relevant SoftPaq you are looking for is sp87753, which you can download from this link: Download SoftPaq.
2. Run the Installer as Administrator
   After downloading, right-click the installation file and choose “Run as administrator.” This will create a folder at C:\SWSetup\sp87753, where you’ll find a user guide in PDF format titled “A User Guide for TPM Config and HpqPswd.pdf.”
3. Initial Check
   You may be tempted to run the “TPMConfig64.exe” file, but it’s essential to check your current TPM version first. Open Device Manager and navigate to “Security devices” to see if it shows Trusted Platform Module 1.2. If it does, you’ll need to make some adjustments.
4. Downgrade Your BIOS
   To successfully upgrade the TPM, you will first need to downgrade your BIOS version from 2.62 to 2.59. You can download this BIOS version from the HP drivers page: HP Z440 Workstation Drivers.
5. Delete the Log File
   Before you proceed with the TPM upgrade, locate and delete the “TPMConfig64.log” file found at C:\SWSetup\sp87753. This step is crucial to avoid issues during the installation.
6. Install TPM 2.0
   Once your BIOS is downgraded to version 2.59, go back to the C:\SWSetup\sp87753 folder, right-click on “TPMConfig64.exe,” and select “Run as Administrator.” This should successfully install the TPM 2.0 upgrade.
7. Reinstall BIOS Version 2.62
   After the TPM upgrade, you might want to reinstall BIOS version 2.62. You won’t find this specific version on the driver page, but you can download it from here: Download BIOS Version 2.62.
8. Final Steps
   Once you have installed BIOS version 2.62, your upgrade will be complete! Double-check the Device Manager again to ensure the Trusted Platform Module now shows as 2.0.

By following these steps, you should have successfully upgraded your TPM from 1.2 to 2.0 on your HP Z440 Workstation. This upgrade will enhance your system’s security, ensuring you stay protected.
