Graphics card usage

Is the top graphics card not being used? It is only on 2%?

Hi Tz2016,
I guess that the temperature of that card is a bit too high at 85°, so it drastically slow down.
You could verify by opening the case, place a fan directly over the hottest card and see if the temperature and the usage are changing

Hi Tz2016,

besides the high temperatures (possible trottling of the cards) it seems your card are in priority mode: the [P] in the info, with priority enabled the cards don't reach the full power, you should keep it enabled in your main card for a smooth workflow in the viewport, and disabled in the others.

cheers

Thank you for both replies.

I think maybe the top card is reporting the stats correctly. In the EVGA window all the card temperature and usages stay pretty much in sync. One card is connecting via a PCIe x1 USB style extender I think maybe that has something to do with it.

The Quadro 4000 is the card that my monitors are connected to. Should the be put in priority mode? It is currently disabled.

Also how do you save a card setup? Everytime I have to disable the Quadro 4000. Is this a demo limitation?

Hi Tz2016,
the order of the cards diplayed in the info bar could be different. What is important is that in GPU-Z or similar app you get constant results.
About the device settings, Priority should be active only on the GPU connected with displays, in your case all the GTX 780 should be unticked. I guess that the top one is the one connected to PCI 1x, for that card also untick the "use for tonemap" option.
With the commercial version you don't need to adjust the device settings everytime

The Priority setting seems to have helped, thank you.
