RTX 5000 Quadro max-q design WAY TOO SLOW !!!

[Nickael7]

Good day, I bought a motherboard for my HP zbook 15 Fury G7 and a GPU, to upgrade from the i7-10850H with a T2000 GPU to a XEON w-10885m with a Quadro RTX-5000 max-q design. But the new setup is extremely slow when I perform some random GPU tests, despite installing all the drivers.

Hello.

This sounds like thermal throttling. Check the GPU temperature from Task Manager or Nvidia Experience (if installed). Compare the results to NotebookCheck review of the same unit. GPU temp much over 70 degrees C shouldn't happen.

The Quadro RTX5000 requires almost twice as much power than the T2000, and it will also output much that much more heat. Your laptop originally came with the basic heat sink solution and HP spec's the laptop with "vapor chamber" assembly for the higher end RTX options. If you didn't upgrade the heat sink assembly along with the GPU, your old heat sink probably just cannot push out the generated heat fast enough, causing the slowdowns.

The Maintenance and Service Guide for your laptop has the part number for the vapor chamber heat sink, p/n: M17047-001

Hi, I've changed the original heatsink with the vapor chamber, I've also changed the thermal paste with the superior "Artic Silver 5" and GPU temperature is normal around 40 degrees Celsius, fans barely make any sound. And power supply is 150 watts. So what is wrong here exactly ?

BTW, thank you so much for replying !!!

Hello again.

I recommend updating the laptop BIOS. The Fury laptop BIOS includes firmware for the graphics card as well. There has been Nvidia Video BIOS updates in the past and even if your BIOS was the latest before you replaced the GPU, the replaced RTX 5000 may have been on a cardboard box for several years, and may have some bugs. You can just run the latest BIOS update again to make sure that's not the case here.

Another thing: The GPU is connected via a "Beam connector" - a small connector board that should be replaced every time the GPU is replaced. A new Beam connector should have been supplied with your RTX 5000 card if it was in a sealed, original HP box. The beam connector slightly deforms when the GPU is installed on top of it, which is why it should be replaced. Perhaps this causes your RTX to not get enough power, which would also explain the low temperatures and poor performance?

Here's an instructional video showing the Beam connector is replaced.

I would also recommend some sort of GPU monitoring software to monitor the power delivery to the GPU. GPU-Z or something like that which can show detailed information about Nvidia cards. The NVidia control panel provided with the drivers might also show this.

There's not much more I can help with your case...:

Make sure your power supply is working and supplying the 150 watts it should. Try with another, verified power supply just in case.

The RTX5000 card may be broken as well - especially if it was a used one, but may be impossible to ascertain unless you had an identical GPU to test with...

Take the laptop to a local HP Service Center which specialises in business/commercial laptops, and ask for their experts' opinion on this. (some HP Service Centers only cater to consumer/commercial laptops which are a lower-end breed)

Here are the right specs for the GPUs !!!

120 W Slim Smart external AC power adapter (configurable with Intel UMA graphics)

150 W Slim Smart external AC power adapter (configurable with NVIDIA Quadro T1000 and T2000 configurations)

200 W Ultra Slim Smart external AC power adapter (configurable with NVIDIA Quadro RTX 3000 or higher configurations)

BINGO !!!

Hey, nice catch! Did you get it working with the 200W PSU?

[Nickael7]

YES, YES AND YES !!!

Beast is fast as hell !!!
