HP Z2 G9 with unresolved video memory error

[RinconRanch]

My Z2 G9 was delivered in May 2024 and worked until October before displaying a video memory error during a hardware diagnosis scan.  It has a factory-installed Ubuntu 22 LTS OS, i9-14900K cpu, and NVIDIA RTX A2000 video card.  HP has been unable to repair or replace this computer in the four months since the warranty case was opened.  I would like to hear from owners of similar computers with the Linux OS and an NVIDIA card.  If you've run the on-board diagnostics that shipped with your computer, do you get a video error?  If this is a problem affecting multiple units, I want to consider the possibility of collective action by a group.

What errors are you seeing?  If driver errors, that is a Ubuntu problem. Did you upgrade to 24?  Are you using closed or open source NVidia drivers?

Are you seeing artifacts or just error messages?  Artifacts can indicate a graphics card problem.

NVidia has memory diagnostics tools for GTX and RTX boards. I have been able to find only the Windows 367 MATS that does not work on RTX and newer cards.  It will show artifact problems if there are any.  If you can find the 400 or 500 series diagnostics please send me a link

If you can pass the F2 or UEFI diagnostics you are unlikely to be granted a warranty service.

There are newer UEFI diagnostics released by HP frequently.  You can create a bootable USB to run the newer UEFI since you do not have windows.

HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Expand the'+'symbol and click the DOWNLOAD button.
The version of the UEFI diagnostics is shown at the left of that DOWNLOAD button.
When you press F2 to run diagnostics please ensure the version is the new one.

Let me know what you find out.

Thanks for the response.  The error occurs when running the on-board diagnostics (accessed from F2).  I have updated BIOS and drivers without that changing the error.  I don't want to look for a "software solution" by going to the 24 OS or picking/choosing drivers.  All evidence is that this is a hardware error.  It's a good thought to look for NVIDIA diagnostics, but my first effort to find that leads to MATS, which (as you noted) does not work for the RTX 4000 cards and higher.  I'll post if I find something.
