Multiple GPUs, how do I identify which is which in octane?

[khdownes]

Hey guys, so I've got a 1070 and a 980ti in my system, and another 980ti on an external Amfeltec cluster.
I have the internal 980ti running my screens, so I want that card to be checked as "use priority" right?
Also, I want the external 980ti to be unchecked "use for tonemap", because otherwise it will slow down the render yeah?

Is there a way for me to identify which GPU is which in the PCI slots so I know which ones to check/uncheck? (being that 2 of them are the same model; they're indistinguishable in octane),

In Octane Standalone the latest versions already include the PCI bus and device ID in the device preferences:

Plugins may not all include the exact same information though.

Nice, thanks Mojave, the C4d plugin doesn't display this info, but I am able to open the standalone and see the order the cards appear (assuming the standalone shows them in the same order as the plugin), and note the PCI bus id for each;

The issue I've run into now though is; when I check my device manager to relate the PCI bus id to the slot on the motherboard, for some weird reason it shows two of the cards as being in the same slot...;

Which is weird, because I'm not currently using the amfeltec cluster (don't need it until I have more than 3 cards), all 3 cards are currently directly on the motherboard, in the order; 980ti - 980ti - 1070

And then, on top of that; the card order/slot numbers/bus ids don't line up at all with how the slot numbers are listed on the Motherboards user manual;

So; from what I can tell, there doesn't seem to be a way of distinguishing which card is which in Windows, when you have identical cards?
Which is probably fine; if I get more cards down the track in the future, I'll try to keep them ordered so there's only one chip type on the mobo, and only the other type on the expansion cluster, so I know which ones to check "use for tonemap" and which ones not to.

Install MSI afterburner, put GPU usage icons for all GPUs to a status bar, and see GPU activity when rendering.

PS Octane may enumerate GPUs differently than in windows.
