Problem with Quadro P5000 video cards in SLI mode on Siemens NX programme.

Hello,

We purchased two Quadro P5000 video cards and set SLI mode in the OS Windows via Nvidia GUI. After this we launch the Siemens NX programme (3D build programme) and we see that the image is twitching. Such a feeling that there is a desync between video cards. There are times when everything is working fine. But more often, everything works badly.

I await your reply, thank you.

Hi adminwd3ll,

Could you provide us some additional information:

  1. OS version
  2. Driver version
  3. Where did you purchase
  4. Workstation make and configuration
  5. Sync card (SLI bridge)
  6. Screen's display, make and number of screens
  7. Connectivity (DV cables, HDMI, etc)
  8. Type of cables being used

Thanks,

My observations:

When I set “Rendering mode SLI” in One Graph Processor that The problem with jerking the image has passed but this is not what we need.

Hi,

Are you not using an SLI bridge to sync the cards? That’s probably the main reason why you are running into desync issues.

Hello,

Ah, I understood the SLI bridge is a physical device.

Yes, we use the SLI bridge.

Hi,

So it seems like you are not using an SLI-certified motherboard and is not using a Quadro SLI bridge. Thus, we have not tested, nor do we officially support, the configuration you deployed—which is likely why the results are unpredictable.

However, the since you also seems to be using only one display, you can try using one GPU to try to isolate if it is providing the same behavior with just GPU…thus, likely something else, such as cable, monitor, etc.

Thanks,
Ryan Park

Hello,

Could you please provide a list of motherboards supported for the P5000 cards?

Thank you
