HP 158A Motherboard replacement

[james963789]

I have HP workstation z620.

for upgrading win 11 and for gaming it is required TPM 2.0. My board doesn't have it.

options are

1-replace motherboard with newer version but comaptible with my current hardwares.

2- I saw someone are insatlling TPM 2.0 module on existing board,but I didn't find any input on my board.

an example as in the link below.

@james963789,

Welcome to our HP Community forum!

Forget about installing a TPM 2.0 module, because even with TPM 2.0, any compatible processor for your PC would still not make it W11 eligible.

If you like your PC, there are a number of reliable and effective bypass methods developed which would allow you to almost effortlessly upgrade your so-called "unsupported device" to Windows 11, such as this easy-to-follow YouTube instructional video shows: https://www.youtube.com/watch?v=lSrmhhigEhY&t=332s&ab_channel=Tips2Fix.

This method uses a clever Microsoft (Server) backdoor Windows 11 install method.

This works great: I have used it myself on a number of legacy HP desktops without any issues whatsoever.

I cannot emphasize enough that this particular W11 upgrade method is hard to beat in terms of simplicity!

The Tips2Fix approach basically modifies the Windows 11 install media by replacing just one file (appraiserres.dll) with the Windows 10 version, which instantly disables all TPM, CPU, and Secure Boot checks without extra prompts or tool-specific steps.

Unless Microsoft changes the installer logic in future builds, this file-swap method will likely remain the quickest workaround for unsupported hardware such as your HP Z620 Workstation.

Anyway, in the off-chance you don't like W11, you have 10 days to roll back to Windows 10. After 10 days, unless you follow the steps outlined in this instructional video, you may need to do a fresh install of Windows 10. Either way, this video will show you what to do with easy-to-follow instructions: https://www.youtube.com/watch?v=2v9_-4JCh_U&ab_channel=Tips2Fix.

Thank you for the explanation.

What about for the game of CALL OD UTY ,Black ops7.

TPM 2.0 and Secure Boot required for PC.

Here is their explanation:

@james963789,

I got you -you're absolutely right that Call of Duty: Black Ops 6/7 (and some other recent games) require both TPM 2.0 and Secure Boot to be enabled -and not just for Windows 11, but also for anti-cheat and game security enforcement.

Unfortunately, your HP Z620 Workstation does not have onboard TPM 2.0 support and cannot be fitted with a Trusted Platform Module (TPM) 2.0. The motherboard lacks a compatible header for a TPM 2.0 module, and the workstation was manufactured during a time when TPM 1.2 was the standard. 

So, even if you bypassed Windows 11's installation requirements (which you can -I showed you how), the game itself would still refuse to launch because its anti-cheat validation directly checks for TPM 2.0 and Secure Boot status at runtime -it's not just a Windows installer check.

 

Your practical options:

1. Play on Windows 10:
   You can still install and play older Call of Duty titles and most modern games that don’t enforce TPM 2.0 or Secure Boot checks.

2. Build or buy a newer system:
   If you want to play Black Ops 7 specifically, you'll need a newer platform (e.g., Intel 8th Gen or newer, or AMD Ryzen 2000 or newer) that includes firmware TPM 2.0 (fTPM/PTT) and supports Secure Boot natively.

3. Keep your Z620 for legacy gaming and work tasks:
   Look, it's still a strong system for classic gaming, 3D rendering, or workstation use -but the TPM limitation is hardware-based and cannot be upgraded or bypassed for games that check TPM/BIOS directly.

In short, bypass methods work perfectly for Windows 11 installation -but unfortunately not for games such as Call of Duty: Black Ops 7 that explicitly validate TPM 2.0 and Secure Boot at the application level.
