HP z440 with two Quadro P5000 not allowing SLI to in Nvidia control pannel

HP Recommended
Z440
Microsoft Windows 10 (64-bit)

Hello everyone,

 

We have several Z440 workstations that we recently installed two Quadro P5000 video cards in each.  Using the Nvidia control panel, we are not given the ability to enable SLI.  If the SLI bridge is removed the Nvidia control panel reflects this by giving a message stating "A higher performance SLI bridge can improve your experience."  but once reconnected the message goes away but still have to option to enable SLI.  Other then the video cards nothing in the systems have been changed.  Lastly, we know SLI works with the systems because the M4000 cards ran in SLI with no issues.  Please let us know any info!

 

 Troubleshooting steps we have attempted:

  1. Updated all system drivers
  2. Updated firmware on the P5000 cards
  3. Updated BIOS
  4. Removed and cleaned video drivers and reinstalled
  5. Attempted to use both older and newer drivers
  6. Used multiple sli bridge connectors
  7. The P5000 cards have two SLI connections "SLI 1" and "SLI 2" we have tried to connect both SLI 1 and SLI 2 at the same time, as well as only one at a time.

the p5000/p6000 in SLI mode is not on the supported list for this model workstation and as such may be blocked by hp for unknown reasions such as excessive power draw, or simply being a card that has not been included for use on a entry /mid range system.

 

as i do not have this model workstation or video card(s) i can only point out HP's offical stance on this setup.
