TS-462 Graphics card recognition ok on ZimaOS but not on QTS

Hello everyone,
To improve Plex, I tried installing an NVIDIA T400 on the PCIe X8 port. But QTS doesn’t see it. Even with a PCIe X16 to PCIe X8 adapter, QTS 5 still doesn’t see the Nvidia.
It’s not a hardware issue, but QNAP has restricted graphics card recognition. If I boot the TRS-462 with ZimaOS from a USB drive, the system instantly finds the T400. The same goes for Plex on ZimaOS, which immediately finds the Nvidia T400.

If I remove the USB drive and reboot on QTS, it finds nothing.

Why restrict the QTS system on this model since the PCIe port is fully compatible?

Does anyone have a tip for teaching QTS 5 how to recognize a graphics card on this TS-462?

No such restrictions that I know of…did you install the NVIDIA driver package ?

PCIe X8 port ???

The TS-462 has only a PCIe Gen 3 x 2 slot

There is no graphics card on the compatibility list

I know I should have thanked you much sooner, but I’ve been working so hard after your replies to find other solutions that I forgot the most basic courtesy. So, thank you!

(And indeed, it’s impossible to install the Nvidia drivers on this device.)

So here’s the other thing. Just because you install a Graphics card, it does not mean that your Plex content will show on that graphics card. The output of a GPU on a QNAP is exceptionally limited…

I’m not sure if Plex takes advantage of hardware acceleration on QNAP with a GPU installed. Someone else will have to comment on that.

On GPU compatible systems (with a compatible GPU) it should show up in the Plex transcoder settings. At least on native installs, on container installs you need to add the GPU via compose to the container.

Regarding the situation you’re experiencing, we suspect there is another possibility: an insufficient power supply.

Thank you for your feedback!
